Re: Update: LOD Cloud Hosting Other Matters

We are still awaiting fresh data sets from Freebase and Bio2RDF (both communities a prepping new RDF data sets). Once received, we will replace the current datasets accordingly. At the current time we have loaded 100% of all the very large data sets from the LOD Cloud [2]. Thus, I would really like owners of RDF data sets depicted in the clouds that cannot locate their data to notify me (via this this mailing list) ASAP. You can use the LOD instance Search Find or URI Lookup or SPARQL endpoint [3] to verify existence of your data (note: we are preserving original data provider URIs). Of the top of my head here are the data sets added since my last update notice: 1. U.S. Census 2. DBP RKB Explorer* and related datsets from Hugh Glaser 3. Gov-Track 4. BBC Programmes, DBtune 5. SemanticBible (this is a small dataset, not in the LOD cloud, but added since linkage will be easy to generate) 6. PingTheSemanticWeb (FOAF Cloud and others) 7. All the Linking Open Drug Data from the LODD project. One more time, if you have a new RDF based Linked Data archive, or an updated dataset, please add pertinent information to the Linked Open Data Sets page [4]. Additional developments re. Amazon Hosting: Amazon have agreed to add all the Linked Open Data Sets to their public data sets collective. Thus, the data sets we are loading will be available in raw data on the public data sets page [5] in Elastic Block Storage (EBS) form; meaning, you can make an EC2 AMI (e.g. a Linux, Windows, Solaris) and install an RDF quad or triple store of choice, then load the data. Of course, we are also going to offer a Virtuoso 6.0 Cluster Edition AMI that will enable you to simply instantiate a personal and service specific edition of Virtuoso with all the LOD data in place, so that you can press go and have the LOD space in true Linked Data from at your disposal in minutes (i.e. the time it takes the DB to start). Work on the migration of the LOD data to EC2 starts next week, so please get your data sets in place if you want to take advantage of this most generous offering from Amazon. We are also going make a few USB devices with chunks of LOD data sets as another distribution mechanism.

Re: Keeping crawlers up-to-date

I know this issue has been raised during the LOD BOF at WWW 2009, but I don't know if any possible solutions emerged from there. The problem we are facing is that data on BBC Programmes changes approximately 50 000 times a day (new/updated broadcasts/versions/programmes/segments etc.). As we'd like to keep a set of RDF crawlers up-to-date with our information we were wondering how best to ping these. pingthesemanticweb seems like a nice option, but it needs the crawlers to ping it often enough to make sure they didn't miss a change. Another solution we were thinking of would be to stick either Talis changesets [1] or SPARQL/Update statements in a message queue, which would then be consumed by the crawlers. That's a lot of data, I wonder if there is a smart way of filtering it down. Perhaps an RDF version of twitter would be interesting, where you follow changes that you're interested in? You could even follow by possibly user, or by SPARQL query, and maybe accross multiple domains. Did anyone tried to tackle this problem already? Cheers! y [1] http://n2.talis.com/wiki/Changeset

Just some data: - We have several hundred entries in the annotator log - most people spend 10 or more minutes to create a reasonable description of themselves. - Even though they all operate some sort of Web sites, less than 30 % of them manage to upload/publish a single *.rdf file in their root directory. - Of those 30%, only a fraction manage to set up content negotiation properly, even though we provide a step-by-step recipe. The effects are - URIs that are not dereferencable, - incorrect media types and and other problems. When investigating the causes and trying to help people, we encountered a variety of configurations and causes that we did not expect. It turned out that helping people just managing this tiny step of publishing Semantic Web data would turn into a full-time job for 1 - 2 administrators. Typical causes of problems are - Lack of privileges for .htaccess (many cheap hosting packages give limited or no access to .htaccess) - Users without Unix background had trouble name a file so that it begins with a dot - Microsoft IIS require completely different recipes - Many users have access just at a CMS level Bottomline: - For researchers in the field, it is a doable task to set up an Apache server so that it serves RDF content according to current best practices. - For most people out there in reality, this is regularly a prohibitively difficult task, both because of a lack of skills and a variety in the technical environments that turns into an engineering challenge what is easy on the textbook-level. As a consequence, we will modify our tool so that it generates dummy RDFa code with span/div that *just* represents the meta-data without interfering with the presentation layer. That can then be inserted as code snippets via copy-and-paste to any XHTML document. Any opinions? Been thinking about this issue for the last 6 months, and ive changed my mind a few times. Inclined to agree that RDFa is probably the ideal entry point for bringing existing businesses onto Good Relations. For a read/write web (which is the goal of commerce, right?), you're probably back to .htaccess, though, with, say, a controller that will manage POSTed SPARUL inserts. I think taking it one step at a time, in this way, seems a sensible approach, though as a community, we'll need to put a bit of wieght behind getting the RDFa tool set up to the state of the art.

Right now IMHO the best bet is probably just to pick whichever format you are most comfortable with (yup it depends) and use that as the single source, transforming perhaps with scripts to generate the alternate representations for conneg. As far as I'm aware we don't yet have an easy templating engine for RDFa, so I suspect having that as the source is probably a good choice for typical Web applications. As mentioned already GRDDL is available for transforming on the fly, though I'm not sure of the level of client engine support at present. Ditto providing a SPARQL endpoint is another way of maximising the surface area of the data. But the key step has clearly been taken, that decision to publish data directly without needing the human element to interpret it. I claim *win* for the Semantic Web, even if it'll still be a few years before we see applications exploiting it in a way that provides real benefit for the end user. my 2 cents.

The reason is that, as beautiful the idea is of using RDFa to make a) the human-readable presentation and b) the machine-readable meta-data link to the same literals, the problematic is it in reality once the structure of a) and b) are very different. For very simple property-value pairs, embedding RDFa markup is no problem. But if you have a bit more complexity at the conceptual level and in particular if there are significant differences to the structure of the presentation (e.g. in terms of granularity, ordering of elements, etc.), it gets very, very messy and hard to maintain. And you give up the clear separation of concerns between the conceptual level and the presentation level that XML brought about. Maybe one should tell Google that this is not cloaking if SW meta-data is embedded... But the snippet basically indicates that we should not recommend this practice.

Re: RDFa for Turtles 2: HTML embedding
2010/3/10 Paul Houle ontolo...@gmail.com Specific proposal for RDFa embedding in HTML Ok, here's a strategy for embedding RDFa metadata in HTML document heads -- make the head of the document be a valid XHTML fragment. Here, now, I'm going to write something like head xmlns=http://www.w3.org/1999/xhtml; xmlns:dcterms= http://purl.org/dc/terms/; meta rel=dcterms:creator content=Ataru Morobishi /head Because the content of the meta area is so simple, compared to other parts of an html document, I feel comfortable publishing a valid XHTML fragment for the head. My understanding is that the namespace declarations will just be ignored by ordinary HTML tools (as they are in backwards-compatible XHTML documents) so there's really no problem here. This does bend the XHTML/RDFa standard and also HTML a little (those namespace declarations aren't technically valid) but I think we get a big gain (even a Turtle-head can embed triples in an HTML document) for very little pain. Any thoughts? This seems sensible. I did have the idea of dumping a whole bunch of RDFa triples in the footer, and setting visibility to zero, but if you can do it safely in the head, problem solved! We're back to the old days of putting meta data in the head of a document. This works for the rel attribute, but what about for property? One nice thing about RDF is that it's a set, so if you put a full dump of triples in one area, even if there's a dup somewhere in your markup, a parser, should remove duplicates.

Just the esw wiki alone requires me to put every set I create into a

10 years ago, looking for RDF on the public Web was like looking for a
needle in a haystack. There wasnt much out there and it was poorly
linked. So a big part of the thinking that led to the foaf/rdfweb
design was to make discovery easier: if you find one rdf doc, you
should be able to find most of the rest by following seeAlso and other
kinds of links.
Why isn't this enough? Perhaps because many of the datasets are huge
db exports, crawlers are often overwhelmed and dissapear into depth-
first holes? Or because we don't publish triples about doc- and
dataset-types in a crawler-discoverable way?
Yes, sort of.
I think the problem is now with metadata for the datasets, which is great.
Actually if everyone published semantic sitemaps and voiD descriptions
etc.,
and we had the tools to re-present the data, we would be well along the
road.
At worst, I might register my site somewhere (as I do with Sindice), say
go
figure. Pages such as the esw ones should then appear magically.
A wiki page is ok for initial bootstrap but we ought to outgrow that
soon...
But I think we may be pleased to say that soon has arrived?
And perhaps if it was easier we would discover that there is so much more
out there that the wiki page hasn't actually been enough for a while. I can
think of 10 interesting datasets that aren't there (that aren't mine).
I am tempted to say that we spend all our time persuading others to take
things like those tables and republish as RDF, but... :-)
And yes, I know this has been a topic before, but we really should be
feeling increasingly embarrassed by this.

Re: A URI(Web ID) for the semantic web community as a foaf:Group
2010/3/26 KangHao Lu (Kenny) kennyl...@csail.mit.edu
Hi all hi Tom,
Does the Semantic Web Interest Group (or the Linked Data community), as a
foaf:Group or something equivalent, has a WebID(URI)? Sorry but I didn't
check whether this has been brought up.
If it doesn't, I would certainly hope that it does have one. I think the
best choice might be something like
http://linkeddata.org/data#swig
With that, we can eat our own dog food and are able to ask the following
questions with SPARQL (doap-based questions)
Question 1: What are all the semantic web people working on?
SPARQL1 :
SELECT ?person ?propject
WHERE {
http://linkeddata.org/data#swig foaf:member ?person.
?project doap:developer ?person .
Question 2: What programming languages do semantic web people use?
SELECT DISTINCT ?person ?lang
WHERE {
http://linkeddata.org/data#swig foaf:member ?person.
?project doap:developer ?person .
?project doap:programming-language ?lang.
}
I mean, from questions of our interest, we can develop *our* Linked Data
and we can also develop the DOAP vocabulary when needed so that, in the
future, we can ask What RDF backends does SWIG people use, Jena or Virtuoso
or Sesame.
FYI:
1. timbl's WebID does link(that is, doap:developer reverse links) to two of
his projects, namely, tabulator and CWM
2. Dbpedia, as a doap:Project, does have a URI
http://www4.wiwiss.fu-berlin.de/is-group/page/projects/Project13, and it
is bidirectionally linked to it's developers.
So, for things to work. I would just recommend to place a N3 file at
http://linkeddata.org/data . It can be maintained manually by Tom or we
can have a very simple form for updating WebIDs of SWIG people.
The spirit is very similar to http://data.semanticweb.org/ , but since
1. I am not an academic person, so I am not even on the list of people
2. I found manually created RDF much more useful than those generated by
machine (this is controversial, I know) and I would be happy to see more
cross-domain links, that is, Tim's URI should be
http://www.w3.org/People/Berners-Lee/card#i
not
http://data.semanticweb.org/person/tim-berners-lee
The choice of http://linkeddata.org/data is because:
1. linkeddata.org It's the first google hit of Linked Data
2. Unlike those sites generated by large systems such as SemanticWiki, I
think linkeddata.org is more flexible to make little changes like this
one.
What do you guys think?
Really nice idea. I find http://crschmidt.net/semweb/doapamatic/ nice.
But I think to really dogfood this properly it has to be an access
controlled datawiki (edit vai sparul/webdav auth via foaf, with web acls).
Then you dont need anyone to maintain it and it should be self healing. We
can iterate on the rules and structure etc. perhaps doing one by hand first,
but I think we have the tools to showcase what the sem web can do here.
Perhaps we can put the source under a shared project. I think between us we
have the expertise to to build it?
Have a nice weekend,
Kenny

I would say foaf-protocols [1] and #swig public-lod tends to be public and open data, imho, but there should be a growing overlap, especially when sparql 1.1 arrives [1] http://lists.foaf-project.org/mailman/listinfo/foaf-protocols Further, with regards the ESW wiki pages, I've not seen any discussions yet on articles, and with some of the documents I do have notes additions etc to add, but don't want to just ad them ad-hoc without at least discussing or running past somebody else. Many Regards, Nathan
Re: What would you build with a web of data?
2010/4/9 Georgi Kobilarov georgi.kobila...@gmx.de Hi Bernard, well, why did I ask people to write about their ideas for apps? My observation is that there are zero real apps using linked open data (i.e. data from the cloud). Not even a single one. Null. After 3 years of linking open data... Agree that there could be more apps, but I've seen a few that are useful. Linked Geo Data and Data WIki spring to mind. There are applications that re-use identifiers, and there are applications that use single, hand-picked data sources. But let's be honest, that's not using the linked data cloud. So, why's that? There must be a reason. Which part of the ecosystem sucks? I think limited support for sparql update means that linked data is largely read only. When sparql 1.1 comes out, hopefully that will change. In my opinion we won't get to solve that question if we stick to linked data will save the planet, one day. But instead, figure out which apps people would want to build now, and then see why it's not possible. If it doesn't work on the small scale of some simple app, how will linked data ever save our planet? Decentralization of data will become a growing theme. 5 years ago there were almost no blogs, but now blogs have changed the way we consume news. The newspaper industry has struggled to adapt to the decentralization of documents. The end user is probably better off for it. I think one big area could be ecommerce, or data driven commerce. Decentralizing transactions (i would again use a data wiki driven solution for this) within our current legal framework could facilitate better control of peoples finances and offer a boost to the economy. Countries like greece could benefit from a boost to their economy. In fact, all countries could. WIth any decentralization process there's going to be winners and losers, but again hopefully the end user will be better off in the long term. WIll this equate to saving the planet? Maybe, just maybe ... :) Cheers, Georgi -Original Message- From: Bernard Vatant [mailto:bernard.vat...@mondeca.com] Sent: Friday, April 09, 2010 12:25 PM To: Georgi Kobilarov Cc: public-lod Subject: Re: What would you build with a web of data?

Sorry if i was unclear, I'm just thinking that in the longer term, this might be valuable to expose to the ouside world. So I was wondering what you do, but as it seems you bind to localhost, that indeed answers my question. There is currently no form of access control, so anyone who can access the endpoint can query/add/update and delete any data. So I would recommend that you firewall it/bind it to localhost: redstore -p 9000 -b 127.0.0.1 Yes that makes sense. I can bind this to localhost, then allow apache to forward requests, based on which WebID is trying to access the store. nick.
Re: Standards Based Data Access Reality (Edited)
2010/4/12 Kingsley Idehen kide...@openlinksw.com All, Edited, as I just realized some critical typo+errors that affect context. Hopefully, you understand what Nathan is articulating (ditto Giovanni). If not, simply step back and as yourself a basic question: What is Linked Data About? Is it about markup? Is it about Data Access? Is it about a never ending cycle of subjective commentary and cognitive dissonance that serves to alienate and fragment a community that desperately needs clarity and cohesion. Experience and history reveal the following to me: 1. Standards based data access is about to be inflected in a major way 2. The EAV (Entity-Attribute-Value) graph model is the new focal point of Data Access (covering CRUD operations). Microsoft, Google, and Apple grok the reality above in a myriad of ways via somewhat proprietary offerings (this community should really learn to look closer via objective context lenses). Note, proprietary is going to mean less and less since their initiatives are HTTP based i.e., it's all about hypermedia resources bearing EAV model data representations -- with varying degrees of fidelity. ** Players and EAV approaches: 1. Microsoft -- OData (EAV with Atom+Feed extension based data representation) 2. Google -- GData (EAV with Atom+Feed based data representation) 3. RDF based Linked Data -- (RDF variant of EAV plus a plethora of data representation formats that are pegged to RDF moniker) 4. Apple -- Core Data (the oldest of the lot from a very proprietary company, this is basically an EAV store that serves all Mac OS X apps, built using SQLite; until recently you couldn't extend its backend storage engine aspect) . ** Reality re. Business of Linked Data: Data as a Service (DaaS) is the first step i.e., entity oriented structured data substrate based on the EAV model. In a nutshell, when you have structured data place, data meshing replaces data mashing. Monikers aside, entrepreneurs, CTOs, and CIOs already grok this reality in their own realm specific ways. Microsoft in particular, already groks data access (they developed their chops eons ago via ODBC). In recent times, they've groked EAV model as mechanism for concrete Conceptual Model Level data access, and they are going unleash an avalanche of polished EAV based applications courtesy of their vast developer network. Of course, Google and Apple will follow suit, naturally. The LOD Community and broader Semantic Web Problem (IMHO): History is a very good and kind teacher, make it an integral part of what you do and the path forward becomes less error prone; a message that hasn't penetrated deep enough within this community, in my personal experience. ** Today, I see a community rife with cognitive dissonance and desires to define a non existent absolute truth with regards to what constitutes an Application or Killer Application. Ironically, has there EVER been a point in history where the phrase: Killer Application, wasn't retrospective? Are we going to miraculously change this, now? ** Has there ever been a segment in the market place (post emergence of Client-Server partitioning) where if you didn't make both the Client and the Server, the conclusion was: we have nothing? We can continue postulating about what constitutes an application, but be rest assured, Microsoft, Google, Apple (in that order), are priming up for precise execution with regards to opportunities in the emerging EAV based Linked Data realm. They have: 1. Polished Clients 2. Vast User Networks 3. Vast Integrator Networks 4. Vast Developer Networks 5. Bottom-less cash troves 6. Very smart people. In my experience, combining the above has never resulted in failure, even if the deliverable contains little bits of impurity. Invest a little more time in understanding the history of our industry instead of trying to reinvent it wholesale. As Colin Powell articulated re. the IRAQ war: If You Break The Pot, You Own It! Folks, we are just part of an innovation continuum, nothing is new under the sun bar, context !! +1 Just to add maybe that CRUD is just one part of the equation, after that can come aggregation, curation, self healing etc. Now I'm trying to work out whether what you've presented is good news or bad. http://www.w3.org/2007/09/map/main.jpg Looking at the WWW Roadmap, are we all headed for the Sea of Interoperability or to be sucked in to a Growing Desert Wasteland? -- Regards, Kingsley Idehen President CEO OpenLink Software Web: http://www.openlinksw.com Weblog: http://www.openlinksw.com/blog/~kidehenhttp://www.openlinksw.com/blog/%7Ekidehen Twitter/Identi.ca: kidehen
Re: [foaf-protocols] semantic pingback improvement request for foaf
2010/4/15 Story Henry henry.st...@bblfish.net Hi, I often get asked how one solve the friend request problem on open social networks that use foaf in the hyperdata way. On the closed social networks when you want to make a friend, you send them a request which they can accept or refuse. It is easy to set up, because all the information is located in the same database, owned by the same company. In a distributed social foaf network anyone can link to you, from anywhere, and your acceptance can be expressed most clearly by linking back. The problem is: you need to find out when someone is linking to you. So then the problem is how does one notify people that one is linking to them. Here are the solutions in order of simplicity. 0. Search engine solution - Wait for a search engine to index the web, then ask the search engine which people are linking to you. Problems: - This will tend to be a bit slow, as a search engine optimised to search the whole web will need to be notified first, even if this is only of minor interest to them - It makes the search engine a core part of the communication between two individuals, taking on the role of the central database in closed social networks - It will not work when people deploy foaf+ssl profiles, where they access control who can see their friends. Search engines will not have access to that information, and so will not be able to index it. A great summary, Henry What about using W3C recommended standard of SPARQL (Update)? I refer to the architecture sketch for web 3.0: http://www.w3.org/DesignIssues/diagrams/social/acl-arch.png It strikes me a (hyper) data file *should* be, first and foremost, updated (write) using SPARUL or WebDAV and HTTP should be used for read operations. So I add you as a friend to my FOAF. And also send you a message with the triples I'd like you to add to your FOAF (use discovery if necessary to find your sparql server, but as tabulator does, you could just send it to the web 3.0 enabled file). You can peform some sanitization/validation/reputation check before adding the friend to your FOAF. It's a simple workflow to get you started, but you can build layers on top (push/pull, realtime, notifications, approvals etc.). Also compatible with FOAF+SSL Auth. 1. HTTP Referer Header -- The absolute simplest solution would be just to use the mis-spelled HTTP Referer Header, that was designed to do this job. In a normal HTTP request the location from which the requested URL was found can be placed in the header of the request. http://en.wikipedia.org/wiki/HTTP_referrer The server receiving the request and serving your foaf profile, can then find the answer to the referrer in the web server logs. Perhaps that is all that is needed! When you make a friend request, do the following: 1. add the friend to your foaf profile http://bblfish.net/#hjs foaf:knows http://kingsley.idehen.name/dataspace/person/kidehen#this . 2. Then just do a GET on their Web ID with the Referrer header set to your Web Id. They will then find in their apache logs, something like this: 93.84.41.131 - - [31/Dec/2008:02:36:54 -0600] GET /dataspace/person/kidehen HTTP/1.1 200 19924 http://bblfish.net/; Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5 This can then be analysed using incredibly simple scripts such (as described in [1] for example) 3. The server could then just verify that information by a. doing a GET on the Referer URL to find out if indeed it is linking to the users WebId b. do some basic trust analysis (is this WebId known by any of my friends?), in order to rank it before presenting it to the user The nice thing about the above method is that it will work even when the initial linker's server does not have a Ping service for WebIDs. If the pages linking are in html with RDFa most browsers will send the referrer field. There is indeed a Wikipedia entry for this: it is called Refback. http://en.wikipedia.org/wiki/Refback Exactly why Refback is more prone to spam than the ping back or linkback solution is still a bit of a mystery to me. 2. Referer with foaf+ssl In any case the SPAM problem can be reduced by using foaf+ssl [2]. If the WebId is an https WebId - which it really should be! - then the requestor will authentify himself, at least on the protected portion of the foaf profile. So there are the following types of people who could be making the request on your WebId. P1. the person making the friend request Here their WebId and the referer field will match. (this can be useful, as this should be the first request you will receive - a person making a friend request, should at least test the link!) P2. A friend of the person making the friend request Perhaps a friend of P1 goes to his

SPARUL seems to me to be asking a lot of technology for something that is really simple, and that is much easier done using much more widely deployed technology. This does not stop it from being deployed later. But we will have a lot more chance integrating foaf into web 2.0 applications if we don't require SPARUL, especially if it is clear that one can do without it. Makes sense. But if you look at the diagram it did have an extra arrow for the web 2.0 servers. As you did raise 6 different ways, I thought I would add the standards compliant web 3.0 way. If you're saying we should concentrate on the low hanging fruit first, it's a great point, but let's not forget that recommended standards do exist here. It is important to have this work in browsers too, so that people can create a friend request and have a web page, they can see the request at. This would allow them to then also DELETE that ping request, or edit it. This can all easily be done using POST, GET and DELETE. And mostly even just POST. Furthermore as we saw doing updates on graphs is still very new, and can easily lead to all kinds of problems. Right, so perhaps need some testing / proof-of-concept here ... let's experimant a bit and see what we find. Finally a ping is arguably not a request to update a graph. It is an action to notify someone of something. That is all. As I mentioned in another thread, what the person notified does with this notification is up to them: it could be - to add the person to their foaf as a friend - to add them as an aquaintance -a spammer -a follower - ignore them - to warn their friends - to call the police Good point. One classic 2.0 pattern is twitter emailing you 'X has become your follower' to represent #X siot:follows #you. Of course blogs and we're back to the classic pingback. I wonder if something like a Talis Changeset could be sent to a 'notification queue' of a recipient ... that may be something like an inbox for them, but instead containing semantically rich updates. When the user and the queue are both online the updates can be process via some kind of workflow. Some updates can be automatic. I really don't see that I want to give other people any decision in updating my graphs. I can give them a space to make a comment, but updating my graph will be something I am going to be very careful about allowing. So I add you as a friend to my FOAF. And also send you a message with the triples I'd like you to add to your FOAF (use discovery if necessary to find your sparql server, but as tabulator does, you could just send it to the web 3.0 enabled file). As stated above, if that is what you want to do, then you don't need SPARUL. You could post a request which contains the triples that you want. Perhaps we can design the ping in such a way, that a change request can be posted, for occasions when you noticed an error in my foaf file Right, you can do it that way too, but web 3.0 servers will be more and more often sparql enabled. You can peform some sanitization/validation/reputation check before adding the friend to your FOAF. It's a simple workflow to get you started, but you can build layers on top (push/pull, realtime, notifications, approvals etc.). Also compatible with FOAF+SSL Auth. I'd be for that, as long as we can start with a very simple ping mechanism that is easy to implement. And that would favor a POST, using an html form. Also it would be nice if this could be done in an intutive way so that we can have deployments with human readable html, that reminds people of SN friend requests. I'll thing about some proofs of concept. Henry

2010/4/30 Matthew Rowe m.r...@dcs.shef.ac.uk Hi First just want to say Li that your app is cool. Good job. Hello, Am cc'ing the foaf-dev mailing (sorry for cross posting)... I just had a look at your fb graph API - foaf rdf service[1], firstly cool stuff, but I have a few points I will address below. I recall Matthew Rowe[2] making a similar service a few years ago which spat out foaf data for a user's fb account, and I recall fb getting annoyed. Am guessing they mentally might have shifted since danbri's good work in getting them involve with SW tech (great work once again by danbri ... *tonnes of applause), I guess we will find out soon ... Indeed it appears that their opinion of 'open data' has shifted. Facebook refused to list the FOAF Generator, which Mischa mentions, in their application directory as they were concerned about having 'their' data exported from Facebook for use by 3rd parties. You can use it here: http://ext.dcs.shef.ac.uk/~u0057/FoafGeneratorhttp://ext.dcs.shef.ac.uk/%7Eu0057/FoafGenerator With the above app you are able to export your entire social graph from fb, thus capturing all your relationships in RDF using FOAF. I guess that with the Open Graph Protocol you can't get such information. I believe there was a restriction facebook has about caching data for more than 48 hours. In the f8 keynote last week mark zuckerberg said that restriction had now been lifted I just built a demo that provides dereferenable HTTP URIs (with RDF/XML data) for Facebook data using data retrieved from the recently announced Graph API by Facebook. see http://sam.tw.rpi.edu/ws/face_lod.html In the demo, I observed inconsistent term usage between the Facebook data API (JSON) and open graph protocol vocabulary. There is also some good potential to get the Facebook terms mapped to FOAF and DCterms terms.

Re: [foaf-protocols] ACL Append
2010/6/18 Nathan nat...@webr3.org Following the recent update of a few of the design issues, one change to the 'Socially Aware Cloud Storage' [1] introduced (among many other interesting updates) the following sentence: Great spot. 'If I want to say that I want to be your friend, for example, I could write that as a simple one-line statement into a friend requests file which you allow me write access to. In fact, I only need append access, and not even read or general write access to that list.' What would the one line statement equivalent to 'I want to be your friend' be? Hand in hand with this, the ACL Ontology has been updated to to include a new acl:Append (in addition to the existing :Control, :Read, :Write) http://www.w3.org/ns/auth/acl#Append 'Append accesses are specific write access which only add information, and do not remove information. For text files, for example, append access allows bytes to be added onto the end of the file. For RDF graphs, Append access allows adds triples to the graph but does not remove any. Append access is useful for dropbox functionality. Dropbox can be used for link notification, which the information added is a notification that a some link has been made elsewhere relevant to the given resource.'

You can create some pretty awesome messes even without OWL:

rdf:next #mylist .
# A looping, branching mess...
#anotherlist a rdf:List ;
rdf:first #anotherlist ;

They might be messy, but they are *possible* structures using pointers,
which is what the RDF vocabulary describes. Its just about impossible to
guarantee that messes can't happen when all you are doing is describing
structures in an open-world setting. But I think the cure is to stop
thinking that possible-messes are a problem to be solved. So, there is dung
in the road. Walk round it.
Could we also apply that to the 'subjects as literals' general discussion
that's going on then?
For example I've heard people saying that it encourages bad 'linked data'
practise by using examples like { 'London' a x:Place } - whereas I'd
immediately counter with { x:London a 'Place' }.
Surely all of the subjects as literals arguments can be countered with
'walk round it', and further good practise could be aided by a few simple
notes on best practise for linked data etc.
IMHO an emphatic NO.
RDF is about constructing structured descriptions where Subjects have
Identifiers in the form of Name References (which may or many resolve to
Structured Representations of Referents carried or borne by Descriptor
Docs/Resources). An Identifier != Literal.
What ARE you talking about? You sound like someone reciting doctrine.
Literals in RDF are just as much 'identifiers' or 'names' as URIs are. They
identify their value, most clearly and emphatically. They denote in exactly
the same way that URIs denote. 23^^xsd:number is about as good an
identification of the number twenty-three as you are ever likely to get in
any notational system since ancient Babylonia.

Re: [ANN] RDFa Developer (1.0b1): RDFa extension for firefox
2010/7/13 Javier Pozueco Pérez javier.pozu...@fundacionctic.org (sorry for cross posting) We are glad to announce the first public release of RDFa Developer, a firefox extension that helps you to correctly annotate web pages with RDFa. This tool enables you to examine the RDFa markup, to query your data using SPARQL and to detect common pitfalls in the use of RDFa. RDFa Developer is an open source tool that is available for download at: http://rdfadev.sourceforge.net. A short demonstration video is also available from the web page. Your comments are very much appreciated. Looks awesome. So reminds me of autopager [1], which many people say is the best ff extension of them all!

XRI are identifiers (URIs) and XDI is a data interchange format (RDF) ...n which XML data from any data source can be identified, exchanged, linked, and synchronized into a machine-readable dataweb just as HTML pages from any content source are linked into the human-readable Web today. What makes this interchange format possible is identifying, describing, and versioning data using XRIs. This is the first that I've heard about this? Who know about the status of this? Who is adopting this? Last I heard the W3C TAG's decision was not to take forward the development of XRI or specs containing XRI, but rather, to explore the use of URIs as the value proposition of the WWW [1]. Subsequently, the OASIS membership voted against it becoming a spec, which was perhaps not received as well as it could have been, by the folks at on the OASIS XRI committee [2]. It's currently still mentioned in some pockets still, namely some of the OpenID specs. The future of XRI I believe is uncertain, with some saying it has died and saying it is alive and well [3] However a new version, 3.0 is coming out later this year. It is purported to have addressed the concerns of the TAG [3] It will be interesting to see what the new version brings, when it comes out.

Long story short, to allow js clients to access our open data we need to add one small HTTP Response header which will allow HEAD/GET and POST requests - the header is: Access-Control-Allow-Origin * This is both XMLHttpRequest (W3C) and XDomainRequest (Microsoft) compatible and supported by all the major browser vendors.

Possible Idea For a Sem Web Based Game?
Hi All I was thinking about creating a simple game based on semantic web technologies and linked data. Some on this list may be too young to remember this, but there used to be game books where you would choose your own adventure. http://en.wikipedia.org/wiki/Choose_Your_Own_Adventure The idea is that every page would have a description, optionally a drawing, and a number or 'links' to new pages. Each 'link' would take you to another page where you would continue the adventure, or reach an ending. I was wondering how hard it would be to model this using linked data principles. 1. Would each 'location' be a document or a resource? Web of Documents vs Web of Resources? 2. Could we use foaf:image and dcterms:desc for the game pages? 3. How would you model the link on each page? It might be interesting to knock something together, maybe there's some data sources for this. Or even better still allow people to change images and descriptions to create a living story, using web standards (webdav sparql update perhaps). I'm not sure how the rendering would work, but perhaps it's easy enough in RDFa once we have a model. Do you think this could work? Thanks in advance Melvin

I'd personally model it like this: #node1 a game:Node ; foaf:name Dark Cave ; foaf:depiction ... ; dcterms:description ... . I'd say that game:Node is not disjoint with foaf:Document. That gives you flexibility - in some cases a node might be a page, and in other cases you might have several nodes described on the same page. Links to other places could be accomplished using: #node1 game:north #node2 ; game:south otherdoc.xhtml#wasteland ; game:east http://example.net/game#node9 . The description itself would have more detailed descriptions of the directions like To the south lies a desolate wasteland.. Directions you'd want would probably be eight compass, points plus up, down, inside, outside. Each node should probably also have co-ordinates (not in WGS84, but a made-up co-ordinate system), along the lines of: #node1 game:latitude 123 ; game:longitude -45 . This would not be used for gameplay, but to aid authoring new nodes. You'd want to have your north triple link to a node that you could plausibly reach by going a short distance north. Hi Toby Thanks for the detailed reply. That sounds excellent, exactly what I was looking form In fact compass directions (plus up and down) bring add a lot to the equation. However most book based text games will have a description added to each link, rather than simply directions to travel. Here's a quick example from googling 'choose your own adventure' : http://www.iamcal.com/games/choose/room.php I think it would be possible to bootstrap some existing stories to the model if we could expand the idea of game:north to have a link and a description, in this way, which I was wondering about. Longer term, I think it would be great to start a simple adventure game in the classic style of 'the hobbit' or 'hitchikers guide' text/graphics based adventures from the 80s, however with the twist that game worlds could link to multiple servers, across the web, allowing anyone to make a 'game withing a game', or web of games. However, that's probably a greater modeling task, so I wanted to start more simply to begin with. So something like #action1 a game:Action dcterms:description Jump on the Barrel game:destination http://example.net/game/node10 I'm pretty new to modeling this stuff, so not sure how much sense that makes? I'm not sure how the rendering would work, but perhaps it's easy enough in RDFa once we have a model.

One possible addition, that would go way beyond what the CYOA books could offer would be for the client to have a stateful store. So when you entered a room, there could be a list of room contents which you could collect into your store. The objects that you've collected could then influence the progress of the game. Probably need to think a bit more about how this should work. That sounds like a logical next step. Your game character can be completely virtual or linked to a foaf : Person. It may be possible to have an agent that acts as a 'dungeon master', which has the ability to say, pick up an #item and put it in your inventory when you issue a command in the right room, for an object that is free. Then when selecting an action in a room, it can check the rules to see if that's possible give your current inventory. I've been talking to someone interested in porting a few simple games to linked data, so we'll see if we can put together some small game worlds, and maybe adding a few puzzles. Maybe you can even get XBOX style Achievements for completing certain levels in different adventures! -- Toby A Inkster mailto:m...@tobyinkster.co.uk http://tobyinkster.co.uk

Would be great to build up a number of clients based on a generic data model. Finally, I also have some state-handling built-into the server including life values and other variables that are tracked to individual players, etc. We may be able to use SPARQL Update to add items to a persona (WebID) ... tracking items is an interesting problem to solve, maybe a game in itself!

Let me know how I can contribute and I'd be happy to so what I can. Sounds good!

Melvster wrote: However most book based text games will have a description added to each link, rather than simply directions to travel. The way I've written this client, the nodes themselves can extend the pre-defined link directions: #node1 #hide-under-rug #node2 . #hide-under-rug rdfs:label hide under the rug ; rdfs:subPropertyOf game:exit . The client will notice you've defined a custom direction, and offer it as an option. One possible addition, that would go way beyond what the CYOA books could offer would be for the client to have a stateful store. So when you entered a room, there could be a list of room contents which you could collect into your store. The objects that you've collected could then influence the progress of the game. Probably need to think a bit more about how this should work. -- Toby A Inkster mailto:m...@tobyinkster.co.uk http://tobyinkster.co.uk

I'd personally model it like this: #node1 a game:Node ; foaf:name Dark Cave ; foaf:depiction ... ; dcterms:description ... . I'd say that game:Node is not disjoint with foaf:Document. That gives you flexibility - in some cases a node might be a page, and in other cases you might have several nodes described on the same page. Links to other places could be accomplished using: #node1 game:north #node2 ; game:south otherdoc.xhtml#wasteland ; game:east http://example.net/game#node9 . I'm now using this ontology to create a game world, and have written a quick client in PHP/ARC2. http://drogon.me/ Try jumping in and moving around. It's all RDF based. I think the next thing I need to model is 'items'. At present need to work out a way to say a location has an item. Any thoughts on a predicate? There are a number of possible implementations, but I think the location document containing an item should be supported. Eventually we'll allow players to own an item, or maybe wear/wield etc. ... but perhaps that's a problem for another day ... PS maybe i should start a new thread on this topic, something like 'Linked Open Gaming'? The description itself would have more detailed descriptions of the directions like To the south lies a desolate wasteland.. Directions you'd want would probably be eight compass, points plus up, down, inside, outside. Each node should probably also have co-ordinates (not in WGS84, but a made-up co-ordinate system), along the lines of: #node1 game:latitude 123 ; game:longitude -45 . This would not be used for gameplay, but to aid authoring new nodes. You'd want to have your north triple link to a node that you could plausibly reach by going a short distance north. I'm not sure how the rendering would work, but perhaps it's easy enough in RDFa once we have a model.

Re: Proposal to assess the quality of Linked Data sources
On 24 February 2011 19:00, Annika Flemming annika.flemm...@gmx.de wrote: Hi, two months ago I presented the findings of my diploma thesis in this mailing list. The aim of my thesis is to draw up a set of criteria to assess the quality of Linked Data sources. My findings included 11 criteria, each comprising a set of so-called indicators. These indicators constitute a measurable aspect of a criterion and, thus, allow for the assessment of the quality of a data source w.r.t the criteria. Since then, I developed a valuation system to assess the quality of a data source based on these criteria and indicators. One part of the valuation system is a generic formalism to represent quality assessment formally. The second part is a proposal of actual valuation methods for the indicators. My proposal can be found here: http://www2.informatik.hu-berlin.de/~flemming/Proposal.pdf Nice paper. An idea to add CORS? http://www.w3.org/wiki/CORS_Enabled [reproduced for convenience] ... What is this about? CORS is a specification that enables true open access across domain boundaries. Why is this important? Currently, client-side scripts (e.g., Javascript) are prevented from accessing much of the Web of Linked Data due to same origin restrictions implemented in all major Web browsers. While enabling such access is important for all data, it is especially important for Linked Open Data and related services; without this, our data simply is not open to all clients. If you have public data which doesn't use require cookie or session based authentication to see, then please consider opening it up for universal javascript/browser access. For CORS access to anything other than simple, non auth protected resources please see this full write up on Cross Origin Request Security. How can I participate? To give Javascript clients basic access to your resources requires adding one HTTP Response Header, namely: Access-Control-Allow-Origin: * This is compatible with both XHR XMLHttpRequest and XDR XDomainRequest, and is supported by all the major Web browsers. I'm posting this proposal in order to evaluate my findings. Therefore, any feedback will be very welcome! Thanks again to everyone participating, Annika
Re: Linked Data, Blank Nodes and Graph Names
On 7 April 2011 19:45, Nathan nat...@webr3.org wrote: Hi All, To cut a long story short, blank nodes are a bit of a PITA to work with, they make data management more complex, new comers don't get them (lest presented as anonymous objects), and they make graph operations much more complex than they need be, because although a graph is a set of triples, you can't (easily) do basic set operations on non-ground graphs, which ultimately filters down to making things such as graph diff, signing, equality testing, checking if one graph is a super/sub set of another very difficult. Safe to say then, on one side of things Linked Data / RDF would be a whole lot simpler without those blank nodes. It's probably worth asking then, in a Linked Data + RDF environment: - would you be happy to give up blank nodes? *Disclaimer* I've not participated in an RDF WG or XG, but am a hobbyist that tries to learn in their spare time, my knowledge if far from complete. That said, I'd be happy to give up blank nodes. One less thing to worry about for the newcomer (my subjective POV), and also it then means that I can maybe do things like c14n and signing subgraphs more easily. - just the [] syntax? - do you always have a name for your graphs? (for instance when published on the web, the URL you GET, and when in a store, the ?G of the quad? I'm asking because there are multiple things that could be done: 1) change nothing 2) remove blank nodes from RDF 3) create a subset of RDF which doesn't have blank nodes and only deals with ground graphs 4) create a subset of RDF which does have a way of differentiating blank nodes from URI-References, where each blank node is named persistently as something like ( graph-name , _:b1 ), which would allow the subset to be effectively ground so that all the benefits of stable names and set operations are maintained for data management, but where also it can be converted (one way) to full RDF by removing those persistent names. Generally, this thread perhaps differs from others, by suggesting that rather than changing RDF, we could layer on a set of specs which cater for all linked data needs, and allow that linked data to be considered as full RDF (with existential) when needed. It appears to me, that if most people would be prepared to make the trade off of loosing the [ ] syntax and anonymous objects such that you always had a usable name for each thing, and were prepared to modify and upgrade tooling to be able to use this not-quite-rdf-but-rdf-compatible thing, then we could solve many real problems here, without changing RDF itself. That said, it's a trade-off, hence, do the benefits outweigh the cost for you? Best, Nathan

Actually my naive quest was to figure how many people had actively published, and possibly still maintain a FOAF profile for themselves, vs the number of profiles stored and maintained in a proprietary social system, vs a profile computed out of their activity on the web for any purpose. Browsing all the answers makes me wonder. I was not aware of so many sources of FOAF information (to tell the truth a great majority of domains quoted by Michael in his 25 top list were totally unknown to me until today). The number I had in mind when asking was rather abou FOAF profiles actively maintained by some primary topic aware of what FOAF is and deliberately using it to be present in the social semantic web. I suppose this number really represents a microscopic part of the millions announced, but I do not know more about it at the end of this day. Except that most FOAF information is certainly produced without people subject of the triples even being aware of it, or even knowing that FOAF exists at all (supposing they are living, real people). Actually it's quite easy to produce FOAF out of any social application data with an open API. So the millions I read about are simply an image of the millions of users of social software using open API, plus the growing number of people for which public data is available such as people listed in Wikipedia and Freebase. So tonight I would turn my question otherwise : Among those millions of FOAF profiles, how do I discover those of which primary source is their primary topic, expressing herself natively in FOAF, vs the ocean of second-hand remashed / remixed information, captured with or without clear approbation of their subjects, and eventually released in FOAF syntax in the Cloud ... I think you can also look out for next generation FOAF profiles that have a public key (WebID), have ACLs and allow a read/write Web eg. through SPARQL Update, WebDAV, PushBack etc. We're starting to see the very first of these emmerge, as standardizations progresses in parallel. This begins to close the loop in terms of a standard way to make a semantic social collaborative space, with FOAF at the heart, and is going to lead to hopefully a whole new wave of apps and innovation on The Web.

Ok so you got this JSON from here: http://graph.facebook.com/kidehen
Then you go on to say that it would be much better if it said:
id: https://www.facebook.com/kidehen#this;
instead of:
id: 605980750
But given that you can't get any JSON from
https://www.facebook.com/kidehen#this, wouldn't it be better if it said:
id: http://graph.facebook.com/kidehen;
or even, as Glenn proposed:
id: http://graph.facebook.com/605980750;
Both of these resolve and produce JSON.
I should have said: http://graph.facebook.com/605980750#this :-)
Chatted with Joe and Nathan about this some time back.
I think there as an argument that said you can get away with not using
the #this ... ill try and dig up the notes if you would like a pointer
So if I wanted to refer to you in my app, it seems like these two would
be quite handy identifiers, and superior to the one you proposed, no?
Yes, as per above.
Kingsley
Best,
Richard
Some observations:
id attribute has value 605980750, this value means little on its own
outside Facebook's data space.
Now imagine we tweaked this graph like so:
{
id: https://www.facebook.com/kidehen#this;
name: Kingsley Uyi Idehen,
first_name: Kingsley,
middle_name: Uyi,
last_name: Idehen,
link: https://www.facebook.com/kidehen;,
username: kidehen,
gender: male,
locale: en_US
}
All of a sudden, I've used a HTTP scheme based hyperlink to introduce a
tiny degree of introspection.
I repeat this exercise for the attributes i.e., Name then using HTTP
scheme URIs, and likewise for values best served by HTTP scheme URIs for
boundlessly extending the object above, courtesy of the InterWeb.
Even if Facebook doesn't buy into my world view re. data objects, my
worldview remains satisfied since I can ingest the FB data objects and then
endow them with the fidelity I via use of URI based Names.
Example Linked Data Resource URL:
http://linkeddata.uriburner.com/about/html/http://linkeddata.uriburner.com/about/id/entity/http/graph.facebook.com/kidehen
.
Example Object Name from My Data Space:
http://linkeddata.uriburner.com/about/id/entity/http/graph.facebook.com/kidehen
.
A little structured data goes a long way to making what we all seek
happen. Facebook, Google, Microsoft, Yahoo! etc.. have committed to
producing structured data. This commitment is massive and it should be
celebrated since it makes life much easier for everyone that's interested in
Linked Data or the broader Semantic Web vision. They aren't claiming to
deliver anything more than structured data. At this time, their fundamental
goal is to leave Semantic Fidelity matters to those who are interested in
such pursuits, appropriately skilled, and so motivated.

These things don't really allow for change. Is there a page where I can find this out in one click? Looks like those pages ask all kinds of questions that require detailed and complicated answers. I am surprised anyone ever answers those things. It's certainly more complex than the Object/Document distinction ;-) Myers Briggs is based on the Jungian analysis of mythology and personality types, with a few additions. Myths being public dreams, and dreams being private myths. The personality types are the lens from which we interpret the inner and outer universal symbols. e.g. Intuitively / Analytically / Senses / Feeling. But the symbols themselves are often the more fascinating parts. An interesting parallel here is the relation to Jung's archetypes of the unconscious and WebID. Both in your dreams, and in mythology, you have symbols where are metaphors that reference some universal concept. WebID is of course a reference to the self ( foaf : Person ). As many of the myths we live with today are 100s of years out of date, and people are searching for something new, perhaps WebID can become a modern symbol, to determine or even evangelize the new personality type of society, post information revolution :) Only slightly off-topic, very relevant here, need to pin down WebID in a sense my dogs can understand. Ok. So you need to give each of your dogs and cats a webid enabled RDFID chip that can publish webids to other animals with similarly equipped chips when they sniff them. From the frequence and length of sniffs you can work out the quality of the relationships. On coming home for food, this data could be uploaded automatically to your web server to their foaf file. These relationships could then be used to allow their pals access to parts of your house. For example good friends of your dog, could get a free meal once a week. You could also use that to tie up friendship with their owners, by the master-of-pet relationships, and give them special ability to tag their pet photos. Masters of my dogs friends could be potential friends. If you get these pieces working right you could set up a business with a strong viral potential, perhaps the strongest on the net. Here to make my point: The Myers-Briggs thing is intuitively rubbish. But with only one or two posts in the ground, it does seem you can extrapolate.

Often the objectives of Linked Data engineers are very different to the objectives of Semantic Web engineers. (A Data Integration technology or a global AI system.) So it is not surprising that the technologies they want might be different, and even incompatible. If I push the parent/child analogy beyond its limit, I can see the forthcoming TAG meeting as the moment at which the child proposes to reason with the parent to try to reach a compromise. The TAG seems to be part of the ownership of the term Linked Data, because the Linked Data people (whoever they are) so agree at the moment - but this is not a God-given right - I don't think there is any trade- or copy-right on the term. A failure to arrive at something that the child finds acceptable can often lead to a complete rift, where the child leaves home entirely and even changes its name. And of course, after such a separation, exactly who would be using the term Linked Data to badge their activities? I would definitely use the Linked Data term to badge activities. The way I see it: 1. Linked Documents aka the Web of Documents, has done quite well. After 2 decades, arguably it's the best technical system built to date. 2. Linked Data, still in its infancy, seems to be exploding. I think the tipping point was late last year when facebook came on board. I hear linked data success stories on a weekly basis. Indeed, the World Bank came on board lately, and it was barely a cause for celebration. That shows me a growing maturity. 3. Linked apps is the era ive been looking forward to the most. We're not even at the very beginning but I'm very excited about the huge potential of web scale apps working together, consuming and producing linked data for both humans and machines. To use a cliche If it aint broken, dont try to fix it No technology remains static, and I can understand proposals for changes. But looking from a 50,000 ft perspective, do people honestly think The Web (and/or Linked Data) is broken? Like others in this discussion I am typing one-handed, after earlier biting my arm off in preference to entering the Range-14 discussion again. But I do think this is an important moment for the Linked Data world.

With the new privacy universal agreement introduced at the beginning of March this year by Google it was only logical that semantic search would be added to expand the data mining tool kit to optimize the utilization of user generated trails of web use. And what will happen to the envisioned academic uses of semantic web technologies and linked data? Are we facing a world according to Google (and FaceBook etc.)? Interesting article.

I'm sure many people are just deeply bored of this discussion.
No offense intended to Jeni and others who are working hard on this,
but *amen*, with bells on!
One of the things that bothers me most about the many years worth of
httpRange-14 discussions (and the implications that HR14 is
partly/heavily/solely to blame for slowing adoption of Linked Data) is
the almost complete lack of hard data being used to inform the
discussions. For a community populated heavily with scientists I find
that pretty tragic.
What hard data do you think would resolve (or if not resolve, at least
move forward) the argument? Some people are contributing their own
experience from building systems, but perhaps that's too anecdotal? Would a
structured survey be helpful? Or do you think we might be able to pick
up trends from the webdatacommons.org (or similar) data?
A few things come to mind:
1) a rigorous assessment of how difficult people *really* find it to
understand distinctions such as things vs documents about things.
I've heard many people claim that they've failed to explain this (or
similar) successfully to developers/adopters; my personal experience
is that everyone gets it, it's no big deal (and IRs/NIRs would
probably never enter into the discussion).
How would we assess that though? My experience is in some way similar --
it's easy enough to explain that you can't get a Road or a Person when you
ask for them on the web -- but when you move on to then explaining how that
means you need two URIs for most of the things that you really want to talk
about, and exactly how you have to support those URIs, it starts getting
much harder.
I'm curious as to why this is difficult to explain. Especially since I
also have difficulties explaining the benefits of linked data. However,
normally the road block I hit is explaining why URIs are important.
Are there perhaps similar paradigms that the majority of developers are
already already familiar with?
One that springs to mind is in java
You have a file Hello.java
But the file contains the actual class, Hello, which has keys and
values.
Or perhaps most people these datys know JSON, where you have file like
hello.json
The file itself is not that important, but it can contain 0 or more
objects, such as
{
key1 : value1,
key2 : value2,
key3 : value3
}
Would this be a valid analogy?
The biggest indication to me that explaining the distinction is a problem
is that neither OGP nor schema.org even attempts to go near it when
explaining to people how to add to semantic information into their web
pages. The URIs that you use in the 'url' properties of those vocabularies
are explained in terms of 'canonical URLs' for the thing that is being
talked about. These are the kinds of graphs that millions of developers are
building on, and those developers do not consider themselves linked data
adopters and will not be going to linked data experts for training.
2) hard data about the 303 redirect penalty, from a consumer and
publisher side. Lots of claims get made about this but I've never seen
hard evidence of the cost of this; it may be trivial, we don't know in
any reliable way. I've been considering writing a paper on this for
the ISWC2012 Experiments and Evaluation track, but am short on spare
time. If anyone wants to join me please shout.
I could offer you a data point from legislation.gov.uk if you like. When
someone requests the ToC for an item of legislation, they will usually hit
our CDN and the result will come back extremely quickly. I just tried:
curl --trace-time -v http://www.legislation.gov.uk/ukpga/1985/67/contents
and it showed the result coming back in 59ms.
When someone uses the identifier URI for the abstract concept of an item
of legislation, there's no caching so the request goes right back to the
server. I just tried:
curl --trace-time -v http://www.legislation.gov.uk/id/ukpga/1985/67
and it showed the result coming back in 838ms, of course the redirection
goes to the ToC above, so in total it takes around 900ms to get back the
data.
So every time that we refer to an item of legislation through its generic
identifier rather than a direct link to its ToC we are making the site seem
about 15 times slower. What's more, it puts load on our servers which
doesn't happen when the data is cached; the more load, the slower the
responses to other important things that are hard to cache, such as
free-text searching.
The consequence of course is that for practical reasons we design the site
not to use generic identifiers for items of legislation

Alice: So, you want to share your in-house thesaurus in the Web as 'Linked Data' in SKOS? Bob: Yup, I saw [inspirational materials] online and a few blog posts, it looks easy enough. We've exported it as RDF/XML SKOS already. Here, take a look... [data stick changes hands] Alice: Cool! And .. yup it's wellformed XML, and here see I parsed it with a real RDF parser (made by Dave Beckett who worked on the last W3C spec for this stuff, beats me actually checking it myself) and it didn't complain. So looks fine! Ok so we'll need to chunk this up somehow so there's one little record per term from your thesaurus, and links between them... ...and it's generally good to make human facing pages as well as machine-oriented RDF ones too. Bob: Ok, so that'll be microformats no wait microdata ah yeah, RDFa, right? Which version? Alice: well RDFa yes, microdata is a kind of cousin, a mix of thinking from microdata and microformats communities. But I meant that you'd make a version of each page for computers to use (RDF/XML like your test export here), ... and you'd make some kind of HTML page for more human readers also. The stuff you mention is more about doing both within the same format... Bob: Great. Which one's the most standard? What should I use? Alice: Well I guess it depends what you mean by standard. [skips digression about whatwg and w3c etc notions of standards process] [skips digression about XHTML vs XML-ish polyglot HTML vs resolutely non-XML HTML5 flavours] [skips digression about qnames in HTML and RDFa 1.1 versus 1.0] ...you might care to look at using basic HTML5 document with say the Lite version of RDFa 1.1 (which is pretty much finished but not an official stable standard yet at W3C) Bob: [makes a note]. Ok, but that's just the human-facing page, anyway. We'd put up RDF/XML for machines too, right? Well maybe that's not necessary I guess. I was reading something about GRDDL and XSLT that automates the conversion, ... should we maybe generate the RDF/XML from the HTML+RDFa or vice versa? or just have some php hack generate both from MySQL since that's where the stuff ultimately lives right now anyway...? Alice: Um, well it's pretty much your choice. Do you need RDF/XML too? Well. maybe, not sure... it depends. There are more RDF/XML parsers around, they're more mature, ... but increasingly tools will consume all kinds of data as RDF. So it might not matter. Depends why you're doing this, really. Bob: Er ok, maybe we ought to do both for now, ... belt-and-braces, ... maybe watch the stats and see what's being picked up? I'm doing this because of promise of interestingly unexpected re-use and so on, which makes details hard to predict by definition. Alice: Sounds like a plan. Ok, so each node in your RDF graph, ... we'll need to give it a URI. You know that's like the new word for URL, but that includes identifiers for real world things too. Bob: Sure sure, I read that. Makes sense. And I can have a URI, my homepage can have a URI, I'm not my home page blah-de-blah? Alice: You got it. Bob: Ok, so what URLs should I give the concepts in this thesaurus? They've got all kinds of strings attached, but we've also got nicely managed numeric IDs too. Alice: Right so maybe something short (URls can never be too short...), ... so maybe if you host at your example.org server, http://example.com/demothes/c1 then same but /c2 /c3 etc. ... or well you could use #c1 or #c2 etc. That's pretty much up to you. There are pros-and-cons in both directions. Bob: whatever's easiest. It's a pretty plain apache2 setup, with php if we want it, or we can batch create files if that makes more sense; this data doesn't change much. Alice: Well how big is the thesaurus...? Bob: a couple thousand terms, each with a few relations and bits of text; maybe more if we dig out the translations (humm should we language negotiate those somehow?) Alice: Let's talk about that another day, maybe? Bob: And hmm the translations are versioned a bit differently? Should we put version numbers in somewhere so it's unambiguous which version of the translation we're using? Alice: Let's talk about that another day, too. Bob: OK, where were we? http://example.com/demothes/c1 ... sure, that sounds fine. ... we'd put some content negotiated apache thing there, and make c1 send HTML if there's a browser, or rdf/xml if they want that stuff instead? Default to the browser / HTML version maybe? Alice: something like that could work. There are some howtos around. Oh, but if c1 isn't

Anyone can find endless examples of how to use HTTP Authentication to access things like sameAs.org. Any Google search will show you it is going to be something like curl --user name:password http://sameas.org/store/games/submit/ Yes sending webid cert is more complex. Something like: wget -qO- --no-check-certificate URI --certificate=./webid.cer --private-key=./webid.key But it does save having to remember username / pw And then the librarian or whoever it is can move on to doing the application, which is what they wanted to do, with the distraction of access mechanisms. Note that some of my users have never heard of RDF - sameAs does identity management for them, and returns something like JSON. Of course, as always, if someone who actually wants to use the service says they would prefer to use WebID, then I will probably allow it when I get a moment, but until then it is way down the list of importance.

On 21 June 2012 00:04, Martin Hepp martin.h...@ebusiness-unibw.org wrote: I can only add to Elena's statement - in fact, it is rather the exception than the rule that a Semantic Web task can be turned into a good game that attracts large, non-nerd audiences. Over the years since our first experiments in 2007, I have come to the conclusion that it is way more rewarding to turn such tasks into Amazon Mechanical Turk tasks (HITs) than to develop games. If we are honest to ourselves, then all of the existing SW games fall short in a terribly in terms of gaming fun and understandability. The difference between Luis van Ahn's successful games and our attempts of using this for the SW is that Luis used challenges where the processing of visual data and applying linguistic competence are the core intelligence task, two areas that are suited for broad audiences and easily link to entertaining game scenarios. But validating mapping axioms between bio ontologies and even open street map data is terribly boring in comparison. Plus, the level of competence needed for cracking the interesting nuts in our data (e.g. subtle forms of polysemy like the city of Munich vs. the district of Munich) restricts the target audience significantly. To be frank, I consider GWAPs for the Semantic Web a dead end and would not invest additional lifetime into it. It was a promising field back then, and has a lot of appeal at first sight, but it will not solve any of our big challenges. Martin, I agree with you that solving esoteric problem in linked data might not be the most fun idea to gamify. However, that does not mean that linked data isnt well suited to producing potentially viral games that have positive side effects (eg for social good). In the last few years simple text based games, using linked social data (eg facebook) have achieved virality of a millions, and even tens of millions of users. What are the big challenges, if they are not to deliver linked data to a larger population in appealing ways?

A second problem that I've seen with the increasing number of games being released over the past years (including ours) is that they produce very similar data sets, mostly in general-purpose domains, for which there are actually knowledge bases available containing that knowledge (as RDF). Having a standard means to reuse such crowdsourced data sets would make the games definitely more valuable.

Game feedback. In general it's a great game. Nice look. Nice sounds. Nice animations. Angry peas style. Some important things: 1 The idea of doing 2 things at once is never going to be popular in games. This talk goes into the reason behind it ( http://fora.tv/2010/07/27/Jesse_Schell_Visions_of_the_Gamepocalypse ) 2 The tutorial didnt really explain what the game was about, I had to play it a few times to work out how to play. Game designers have 3 goals: - Interest your users for 15 seconds - Interest your users for 15 minutes - Interest your users for 15 hours The first step needs some where here. 3 For a game to be popular / viral, it needs to be 'social'. What this means is use social linked data. Facebook is quite good at this, but the linked data cloud can take this further an order of magnitude. As I mentioned before you need to also tie your achievements to your login profile, otherwise it's just another silo. Some links: How to be an indie game developer: http://www.mode7games.com/blog/2012/06/12/how-to-be-an-indie-game-developer/ Post on the mechanics of social games: http://techcrunch.com/2010/08/01/the-new-games -people-play-game-mechanics-in-the-age-of-social In general : making good games is HARD, but can be hugely rewarding. Linked data is uniquely placed to make games at web scale. The first people to crack this are on to something very big. But you have to try and capture modern social mechanics. A great can take linked data to the next level, and virally bootstrap web 2.0 if done right. This effort was a really good try, lots of the hard parts are done, but still some ways to go.

Of course, we need to live with a bogus HTTP Content-Type, but that's unfortunately quite common even for people who control their own server. Thanks again to Manning for the quick response! Exactly! Linked Data should be discoverable to a variety of user agent profiles: 1. HTML oriented -- user link/ based Web Linking pattern in head/ 2. HTTP oriented -- repeat via Link: 3. RDF aware -- in the content include wdrs:desceribedby, foaf:topic etc. relations. David, In addition to the above, is it possible to have the mime type fixed? At the current time, I still get: Hi Kingsley, Maybe. Manning js using the Yahoo! Small Business Web Hosting service. I have asked some people at Yahoo! to repair the Content-Types and I will revisit this if they don't. How about this: 1. They add another link/ relationship to head/ 2. The link points to a Turtle doc in a data space you control -- absolute worst case (as I believe you already have your own space), just can get free data space from the likes of Dropbox, SkyDrive, Amazon S3 etc 3. You set the correct content-type for the Turtle doc in your data space 4. Ditto fixing any other issues e.g., entity name ambiguity etc.. 5. Done :-) I've often thought there should be an open world, distributed, fault correction service for sites that give the wrong content type. Could solve a lot of problems.

Without Web- and Internet-scale Linked Data this simply would be achievable, without opening up yet another artificial silo. Works for me with twitter and persona Great! Anyone else? All: Basically, all you really have to do is just let me (the resource owner) know how you want to be identified. Examples would include: 1. Twitter -- http://twitter.com/userid e.g., http://twitter.com/kidehen 2. LinkedIn -- http://www.linkedin.com/in/userid e.g., http://www.linkedin.com/in/kidehen 3. Facebook -- http://www.facebook.com/userid e.g., https://www.facebook.com/kidehen 4. etc.. Basically, each of these social networking/media service providers mints a verifiable URI for its members. In many cases, these days, you can verify these URIs by testing for control over said URIs using protocols such as OpenID, OAuth etc.. Naturally, you can also leverage WebID and its WebID+TLS authentication protocol in the same manner, just by sharing your WebID with the resource owner (me). Remember, this is a deceptively simple example of the power of Linked Data applied to the following problems: 1. verifiable identity 2. resource access authorization . Also note, we are going to be releasing this Javascript control as part of our ODS social web framework project on Github. Awesome! I would definitely like to use something like this in my apps for login. For anyone that hasnt tried it yet, I'd encourage you to give it a go.

Proposal: register /.well-known/sparql with IANA
May I propose that we register the well known address /.well-known/sparql with IANA. This could be a sparql endpoint for the domain queried, and a helpful shortcut for both web based discovery, and also write operations via sparql update.

It is a fact that Linked data as publish some stuff and they will come, both new publishers and consumers has failed. Of course it hasn't. How have we (this community) arrived at a LOD Cloud way in excess of 50 Billion+ useful triples? I just can't accept this kind of dismissal, it has adverse effects on the hard work of many that are continuously contributing to the LOD Cloud effort. The idea of putting some extra energy would simply be useless per se BUT it becomes wrong when one tries to involve others e.g. gullible newcomers, fresh ph.d students who trust that hey if my ph.d advisor made a career out of it, and EU gave him so much money it must be real right? Teach people how to make little bits of Linked Data in Turtle. The RDBMS world successfully taught people how to make Tables and execute simple queries using SQL, in the ultimate data silos i.e., RDBMS engines. The same rules apply here with the advantage of a much more powerful, open, and ultimately useful language in SPARQL. In addition to that, you have a superior data source name (DSN) mechanism in HTTP URIs, and superior Data Access that's all baked into HTTP. Last year I ensured every employee at OpenLink could write Turtle by hand. They all performed a basic exercise [1][2]: describe the yourself and/or stuff you like. The process started slow and ended with everyone having a lot of fun. Simple message to get folks to engage: if you know illiteracy leads to competitive disadvantage in the physical (real) world, why accept illiteracy in the ultra competitive digital realm of the Web? Basically, if you can write simple sentences in natural language, why not learn to do the same with the Web realm in mind? Why take the distracting journey of producing an HTML file when you can dump content such as what follows into a file? ## Turtle Start ## a #Document . #topic #i . #i #name Kingsley Idehen . #i #nickname @kidehen . ## Bonus bits: Cross References to properties defined by existing vocabularies ## In more serious exercises this section would be where DBpedia and other LOD cloud URIs kick-in. #name owl:equivalentProperty foaf:name . #topic owl:equivalentProperty foaf:topic . #nickname owl:equivalentClass foaf:nick . #Document owl:equivalentClass foaf:Document . #i owl:sameAs http://kingsley.idehen.net/** dataspace/person/kidehen#thishttp://kingsley.idehen.net/dataspace/person/kidehen#this . ## Turtle End ## Don't underestimate the the power of human intelligence, once awakened :-) The above is trivial for any literate person to comprehend. Remember, they already understand natural language sentence structure expressed in: subject-predicate-object or subject-verb-object form. IAs community of people who claim to have something to do with research (and not a cult) every once in a while is learn from the above lesson and devise NEW methods and strategies. Yes, and the lesson we've learned over the years is that premature optimization is suboptimal when dealing with Linked Data. Basically, you have to teach Linked Data using manual document production steps i.e., remind them of the document create and share pattern. Once this is achieved, they'll immediately realize there's a lot of fun to being able to represent structured data with ease, but at the expense of limited free time -- the very point when productivity oriented tools and services come into play. Nice! There should be official sem web tests, badges and achievements based on passing things like this. Described in linked data of course! In other words, move ahead in a smart way. Yes, but there isn't one smart way. For we humans the quest is always rife with context fluidity. Thus, horses for courses rule always applies. No silver bullets. I am by no mean trowing all away. Good! * publishing structured data on the web is already a *huge thing* with schema.org and the rest. Yes, but that's a useful piece of the picture. Not the picture. HTML+Microdata and (X)HTML+RDFa are not for end-users. Turtle is for end-users, so it too has to be part of the mix when the target audience is end-users. Why? because of the clear incentive SEO. SEO is only a piece of the picture. Yes, everyone wants to be discovered by Google, for now, but that isn't the Web's ultimate destiny. What people really want is serendipitous discovery of relevant information as an intrinsic component of the virtuous cycle associated with content sharing via the Web. * RDF is a great model for heterogeneous data integration and i think it will explode in (certain) enterprises (knowledge intensive) RDF provides specific benefits lost in a warped narrative. It USP boils down
