Java Language Ontology and .java to RDF parser?

Get 40k to startup your startup in Chile
Hi Guys, I am helping the Startup-Chile program. http://techcrunch.com/2010/12/18/chile%E2%80%99s-grand-innovation-experiment/ http://startupchile.org/ We will give you 40k, no strings attached, if you startup in Chile. The networking is great and the experience itself is very innovative. You will be benefited from being the first, which will create unusual networking opportunities. In SF you're usually just one more guy The project is mega-ambitious in itself and its objective is to bootstrap a silicon valley / innovation pole here in Chile by importing a human network and letting it blend with the local network. This will attract talent, generate success, stories, etc. Given that Chile is small, it has a pretty big chance of succeeding. In contrast with other projects, they are not focusing on infrastructure, universities, etc which is an indirect route. They are just bringing in entrepreneurs. You need to have a startup with an initial business model, and someone needs to come here. I can point you to more information if you're interested. Think of this as a bootstrapping paid leave in a totally new place where your mom won't be calling you every 5 minutes. You will meet other entrepreneurs. Personally. I think this is a fun opportunity. Disclaimer: I am not getting any money out of this. Most chilean entrepreneurs are simply helping. We love the idea that we can create a high tech sub-culture right here. And I love the fact that I am meeting more people and ideas than I usually do in California in the same span of time. That's the main reward. Also. I am available to partner up if someone has a startup that's within my are of expertise. I can contribute execution, talent, and my head of expertise.

You can take the Microsoft Access dump, re-org the SQL data if need be, zap it through the RDF Views Wizard (using ODBC connection to Access) and you're set re. RDF based Linked Data Space. So you noticed there is a MsSQL dump :) My real problem is not doing this part, I do it often. The question was aimed at taking advantage of network effect. 1. If it is done, don't do it again 2. Reuse IDs which will eventually align my dataset with another datasets. For example, someone will add images to these categories, and my apps will benefit from that with a simple import. I think Virtuoso's RDF Views are best ( in fact, crucial ) when dealing with a live dataset which is stored in an RDBMS and being operated on by other apps. Like sugar CRM for example.

Re: FW: Failed to port datastore to RDF, will go Mongo
Sorry, I forgot to add something critical. Ease of integration ( moving triples ) is just the beginning. Once you get a hold on the power of ontologies and inference as views your data starts becoming more and more useful. But the first step is getting your data into RDF and the return on that investment is SPARQL and the ease to integrate. I usually end up with several transformation pipelines and accesory TTL files which get all combined into one dataset. TTLs are easily editable by hand, collaboratively versiones, while giving you full expressivity. TTL files alone are why some developers fall in love with Linked Data.

After a few days, I'm now over the whole idea of porting WDMMG to RDF. Having written a long technical pro/con email before (that I assume contained nothing you don't already know), I think the net effect of using RDF would be the following: * Lots of coolness, sucking up to linked data people. * Further research regarding knowledge representation. I will quickly outline some points that I think are advantages from a developer POV. ( once you tackle the problems you outline below, of course ). * A highly expressive language ( SPARQL ) * Ease of creating workflows where data moves from one app to another. And this is not just buzz. The self-contained nature of triples and IDs make it so that you can SPARQL select on one side and SPARQL insert on another. I do this all the time, creating data pipelines. I admit it has taken some time to master, but I can peform magic from my customer's point of view. vs. * Unstable and outdated technological base. No triplestore I have seen so far seemed on par with MySQL 4. * You definitely need to give Virtuoso a try. It is a mature SQL database that grew into RDF. I Strongly disagree with this point as I have personally created highly demanding projects for large companies using Virtuoso's Quad Store. To give you a real life case, the recent Brazilian Election portal by Globo.com ( http://g1.globo.com/especiais/eleicoes-2010/ ) has Virtuoso under the hood and, being a highly important, mission critical app in a major ( 4th ) media company it is not a toy application. I know many others but in this one I participated so I can tell you it is Virtuoso w/o fear mistake. * No freedom wrt to schema, instead modelling overhead. Spent 30 minutes trying to find a predicate for Euro. Yes! This is a major problem and we as a community need to tackle it. I am intrigued to see what ideas come up in this thread. Thanks for bringing it up. As an alternative, you can initially model everything using a simple urn:foo:xxx or http://mydomain.com/id/xxx schema ( this is what I do ) and as you move fwd you can refactor the model. Or not. You can leave it as is and it will still be integratable ( able to live along other datasets in the same store ). Deploying the Linked part of Linked Data ( the dereferencing protocols ) later on is another game. * Scares off developers. Invested 2 days researching this, which is how long it took me to implement OHs backend the first time around. Project would need to be sustained through linked data grad students. * Less flexibility wrt to analytics, querying and aggregation. SPARQL not so hot. Did you try Virtuoso? Seriously. It provides out of the box common aggregates and is highly extensible. You basically have a development platform at your disposal. * Good chance of chewing up the UI, much harder to implement editing

Re: [Virtuoso-users] Reification alternative
Hi Ivan, Hehe, I knew you were going to jump in, that's why I CC'd this to virtuoso-users ;) Before getting into the content of your response, let me just say this: I think Mirko's example is actually really common. Every application that I have built needs to keep track of ( at least ) two other dimensions beyond the core data model/state: * Time ( Be it audit trail or just timestamp ) * Author You provide some really valuable tips in your reply as to how you can tune your Virtuoso installation to actually accomplish this. On Wed, Oct 13, 2010 at 3:49 PM, Ivan Mikhailov imikhai...@openlinksw.com wrote: Hello Aldo, I'd recommend to keep RDF_QUAD unchanged and use RDF Views to keep n-ary things in separate tables. The reason is that the access to RDF_QUAD is heavily optimized, we've never polished any other table to such a degree (and I hope we will not :), and any changes may result in severe penalties in scalability. Triggers should be possible as well, but we haven't tried them, because it is relatively cheap to redirect data manipulations to other tables. Both the loader of files and SPARUL internals are flexible enough so it may be more convenient to change different tables depending on parameters: the loader can call arbitrary callback functions for each parsed triple and SPARUL manipulations are configurable via define output:route pragma at the beginning of the query. Interesting! ;) From the docs: output:route: works only for SPARUL operators and tells the SPARQL compiler to generate procedure names that differ from default. As a result, the effect of operator will depend on application. That is for tricks. E.g., consider an application that extracts metadata from DAV resources stored in the Virtuoso and put them to RDF storage to make visible from outside. When a web application has permissions and credentials to execute a SPARUL query, the changed metadata can be written to the DAV resource (and after that the trigger will update them in the RDF storage), transparently for all other parts of application. Where can I find more docs on this feature? ( I don't actually need this, just asking ) In this case there will be no need in writing special SQL to triplify data from that wide tables because RDF Views will do that automatically. Moreover, it's possible to automatically create triggers by RDF Views that will materialize changes in wide tables in RDF_QUAD (say, if you need inference). So instead of editing RDF_QUAD and let triggers on RDF_QUAD reproduce the changes in wide tables, you may edit wide tables and let triggers reproduce the changes in RDF_QUAD. The second approach is much more flexible and it promise better performance due to much smaller activity in triggers. For cluster, I'd say that the second variant is the only possible thing, because fast manipulations with RDF_QUAD are _really_ complicated there. Great to know all this! Again, I think the possibility to mix and match SPARQL + SQL via RDF Views, triggers, output:route, etc is a really good solution for 4ary relations. Built-in Time Dimension is something I am looking forward to implement to some of my applications as they provide enormous business value.

Virtuoso's Quad Store is implemented atop an RDF_QUAD table with 4 columns (g, s, p o). This is very straightforward. It may even seem naive at first glance. ( a table!!? ). Now, the great part is that the architecture is very open. You can actually modify the table via SQL statements directly: insert, delete, update, etc. You can even add columns and triggers to it. Some ideas: * Keep track of n-ary relations in the same table by using accessory columns ( time, author, etc ). * Add a trigger and log each add/delete to a separate table where you also store more data * When consuming this data, you can use SQL or you can run a SPARQL construct based on a SQL query, so as to triplity the n-tuple as you wish. The bottom suggestion here is: Take a look at what's possible when you escape SPARQL only and start working in a hybrid environment ( SQL + SPARQL ). Also note that the self-contained nature of RDF assertions ( facts, statements ) makes it possible to do all sorts of tricks by taking them into 3+ tuple structures. My coolest experiment so far is a time machine. I log adds and deletes and can recreate the state of the system ( Quad Store ) up to any point in time. Imagine a Queue management system where you can replay the state of the system, for example. Regards, A -- Aldo Bucchi @aldonline skype:aldo.bucchi http://aldobucchi.com/

Re: Nice Data Cleansing Tool Demo
Hi David, I love it and I NEED it ;) Awesome work, really. I heard it will be opensource so I will probably be able to extend it myself, but here are some ideas for (missing?) features: * Importing custom Lookups/Dictionaries ( to go from text to IDs or the other way around ). Maybe this is possible using a different hook for the reconciliation mechanism. * Related: Plug in other reconciliation services ( not sure how this stands up to freebase biz alignment ) * Command line engine. To add a GW project as a step in a traditional transformation job and execute steps sequentially. * Expose Gazetteers ( dictionaries ) generated within the tool ( when equating facets ) I have other ideas but I need to try it first it looks like you've covered a lot of ground here. Amazing, Amazing. Thanks!

This part is what I call an innovation slot since we have hooked it into our DBMS hosted faceted engine and successfully used it over very large data sets. Kingsley, I'm wondering: How did you do that? I tried it myself, and it doesn't work. Did I indicate that my demo instance was public? How did you come to overlook that? I wasn't referring to a demo of yours, but to the general task of using Pivot as a frontend to a faceted browsing backend engine. Pivot can't make use of server-side faceted browsing engines. Why do you speculate? You are incorrect and Virtuoso *doing* what you claim is impossible will be emphatic proof, nice and simple. Pivot consumes data from HTTP accessible collections (which may be static or dynamic [1]). A dynamic collection is comprised of CXML resources (basically XML) . I don't speculate. Which parts of my does not work and can't use did sound like a speculation? You need to send *all* the data to the Pivot client, and it computes the facets and performs any filtering operation client-side. You make a collection from a huge corpus of data (what I demonstrate) then you Save As (which I demonstrate as the generation point re. CXML resource) and then Pivot consumes. All the data is Virtuoso hosted. There are two things you are overlooking: 1. The dynamic collection is produced at the conclusion of Virtuoso based faceted navigation (the interactions basically describes the Facet membership to Virtuoso) 2. Pivot works with static and dynamic collections . *I specifically state, this is about using both products together to solve a major problem. #1 Faceted Browsing UX #2 Faceting over a huge data corpus.* Virtuoso is an HTTP server, it can serve a myriad of representations of data to user agents (it has its own DBMS hosted XSLT Processor and XML Schema Validator with XQuery/XPath to boot, all very old stuff). Yes, you make a collection and save as that to CXML, exactly! That is not using Pivot as a frontend to Virtuoso. Sure, you can construct a small dataset from a huge dataset using SPARQL, or your Virtuoso facet engine or whatever. And then export that resulting dataset to Pivot collection XML and load that CXML into Pivot. But that is very different to using Pivot as a frontend to a huge data set. BTW -- how do you think Peter Haase got his variant working? I am sure he will shed identical light on the matter for you. Yes, Peter, please do. From what I saw in the Fluidops demo, it works exactly as I wrote above: A sparql-query constructs a small dataset from the sparql endpoint, converts that via a proxy to CXML and loads it into Pivot. I don't say Pivot doesn't make a nice demo, or a useful tool to explore a small dataset via faceted filtering. But it's not a frontend that can be put on top of a faceted browsing engine like http://developer.nytimes.com/docs/article_search_api The last thing I want is an argument about this; but surely virtually every service in the world; faceted browsing included, works by querying a large dataset to get a smaller set of results, transforming it in to a the needed format an then displaying? sounds like every system I've ever seen from the simple html view of an sql query right up to the mighty google itself. Maybe I'm being naive here; what am I missing? Nathan, You're not missing much. From what I see: Georgi's point is that the level of integration is not ideal. It is basically a load style integration, not a connect style integration. Kingsley's point is that they can be integrated, and he has a demo to prove it. Both are right ;) I can relate to both but I lean towards Kingsley's because he is, as usual, projecting. He knows that this integration is enough to make a point, and that the rest will happen. Show the value! The architecture will follow. ( this is what M$ does all the time ). Plus they already have a lock-in on the runtime side and seadragon tech, so I think they can afford to open the platform up some more on the integration side of things.

National Identification Number URIs ( NIN URIs )
Hi, All countries have a National Identification Number scheme ( NIN ). http://en.wikipedia.org/wiki/National_identification_number Also, all countries have code points in different schemes. So, can't we combine both to create a de-facto URI for people based on country ids? For example: http://dbpedia.org/nin/cl/14168212 That would be me based on my Chilean NIN. Is there some namespace for this already? When you have real world problems, like we have now in Chile, it is simple solutions like these that would make integration easier.

It’s the killer app for the semweb, in Microsoft land. Cool! This topic is coming up again ;) I agreee. From the Java perspective this is very much what I found too. When I first learned RDF I was really intrigued about how it related to Object Oriented Programming, which I was familiar with. So I tried to write a mapper for it to Java, which to my astonishment was really a lot easier than I thought. This really helped me understand how OO programming and the semantic web mesh together. Having these tools for run of the mill programmers is really important as Peter points out to get them to overcome the fear of the new: by bringing the semweb back to something they know. This thought is what led me to develop the Sommer library: https://sommer.dev.java.net/sommer/index.html Doin this made it clear that really the major difference is that we name things and fields with URIs. The next difference is that of Graphs, which is a little more difficult to merge correctly into OO languages (or for that matter most traditional programming languages). Still before tools such as Hibernate and such for Java came out, people worked with SQL directly. So people went on a long time with this pain point... To start off we need really good examples of the usage of RDF. And I think foaf+ssl is that key driver, because it has the ability to give people access to things they would not otherwise have had access to: eg: going to a party. Henry: Here's an idea. Instead of trying to bake this cake by ourselves, can you tap into Martin Odersky's team and propose some use cases? I could help with that if you get his attention. He's the guy behind Scala and they are on a rampage these days. Now. Even w/o tweaking the compiler or the grammar to support URIs, the DSL capabilities of Scala make it possible to do beautiful things: http://code.google.com/p/scardf/ That project is a good start but there are still some issues to address. I have my own experimental framework but, just as you describe, N1 issue is native type integration and we should explore this at a lower level. If we could just get native URIs / XSD datatypes things would be awesome. Then, Number 2 is graph traversal which can be solved by having some sort of path language baked in, ( which is compiled to a single query underneath instead of being evaluated step by step via API, which is the case in scardf ) . Number 3 is datasource management. Tying up a datasource as an implicit value or bound to a thread. Nothing new under the Sun here ( pun intended ) ;) This is where things get interesting as the datasource could actually be a full blown Linked Data client such as Virtuoso with Spongers turned on. Finally. My initial look at the Scala grammar suggests that we should be able to fit in URIs. There is support for XML literals and URIs are easily recognizable as they have a strict syntax. Qnames could also happen.

Re: Introducing BOLD (Business Of Linked Data) Discussion Space

Meeting with customers and having to come up with pitches that are both * Attractive enough to compete with current established technologies * Grounded in practical reality ( it is easy to fall into the snake-oil side of things when talking about the future ) In my experience this has been very hard but its getting easier thanks to the amount of technology and showcases ( in particuar, DBpedia and the rest of the LOD setup as well as the many consultants and other vendors that are emerging ). Also, and this is to Kingsley's credit. Having Virtuoso has been unvaluable in terms of being able to relate to something with built-in prestige. It is quite different to say: - This is the future Than to say - This tool here, which has a proven track record and looks like something you understand ( a database ), allows you to do this and that. And I can show you. In retrospect, this discussion space should have been created much earlier; especially, as messaging surrounding Linked Data remains challenging esp. with those outside the core Semantic Web community. Anyway, if you are more interested in the business and marketing aspects of HTTP based Linked Data, you now have a space for open discussion and brainstorming. Let's get it on!

Need help mapping two letter country code to URI
Hi, I found a dataset that represents countries as two letter country codes: DK, FI, NO, SE, UK. I would like to turn these into URIs of the actual countries they represent. ( I have no idea on whether this follows an ISO standard or is just some private key in this system ). Any ideas on a set of candidata URIs? I would like to run a complete coverage test and take care I don't introduce distortion ( that is pretty easy by doing some heuristic tests against labels, etc ). There are some border cases that suggest this isn't ISO3166-1, but I am not sure yet. ( and if it were, which widely used URIs are based on this standard? ). Thanks!

Commercial Linked Data Initiatives list?
Hi,
I was wondering if anyone is keeping track of major commercial Linked
Data initiatives such as BBC, NYT, BestBuy, etc.
A vocabulary for annotating these would be oh so meta-meta ;)
Something like
select distinct ?initiative ?customer ?sector where { ?customer
initiative ?initiative . ?customer industrysector ?sector }
Would be quite interesting to have.
Oh, and plotting them on a timeline!

Hi Aldo --
It's one thing to have linked data.
It's quite another thing to enable non-programmers to ask questions that
no-one has thought to pre-program for them.
Fortunately, projects such as the Tabulator and the system online at the
site below [1] are starting to point the way towards higher level platforms
on which non-programmers can put linked data to their own uses.
Perhaps a useful extension to TIMBL's recent paper [2] might be a list of
such platforms, and other design approaches? (Tim does mention the
Tabulator in passing).
Yes you're right, eventually we will be able to provide casual users
with such tools.
Note that faceted browsing is already perhaps usable for the task I describe.
However, my post was mainly aimed to the data side. A programmer ( one
of us ) could craft a specific visualization for this if the data was
available.
I think it would be great to have such visualization, or provide the
fodder for others to craft it. This could depict the current state of
the Linked Data battlle in commercial land ;)
Putting the wins up for others to see is always positive. Putting them
out in Linked Data for real time consumption is interesting in many
ways.

Linked Data tech market; Data Web Servers, anyone?
Hi guys, Believe me or not, we will soon have a Data Web Server market ( just as we once had Document Web Servers market ). Data Web Servers publish data/rdbms to the Data Web. Just like Document Web Servers publish your document/file system to the web. Of course, Data Web Servers will also be Document Web Servers. In this hypothetical context, what would be a proper way of describing RDFa? A way of embedding data into Document Web Servers ? Probably, yes. Anyway, for me RDF is a non-intrusive augmentation of the URI address space by adding a second dimension ( columns ), just like URIs were a non-intrusive augmentation of the IP address space by adding more rows ( to reach documents *within* computers ). It baiscally answers this question: how do I put my spreadsheet/table on the web? I have been selling semweb as middleware for 6 years using such stories and explanations, and they just make total sense. I have accumulated quite a bit of sales material. So, here's a ( totally raw ) sampler ;) http://files.getdropbox.com/u/497895/semweb-animation-reel.mov OK. Now annihilate me ;) Blasphemy! But, seriously. Next time you're in front of a customer and he's showing you the door after 20 mins of SW story, you'll probably remember this ;) Regards, A PS. Anyway, when the MKT guys kick in, all the SW purity will be left to the annals of history.

Best Hugh Yes ! François So if the answer is Yes. Then do you mean things in the ABox and TBox? Must be clear here as being too generic leads to confusion. Link generators are working at the instance level (ABox), they generate links between instances. They need some input, a specification of what should be interlinked. We think this specification can be lifted to an alignment between vocabularies (TBoxes). Well we are not 100% sure this will work, that's why we would like to get such tools and their linkage specifications. I can take an example, interlinking persons: one dataset is described with FOAF, the other with VCard. ?x foaf:name ?name. ?y vc:n [ vc:family-name ?fn; vc:given-name ?gn. ]. the linkage specification might be something like: if compare(?name, concat(?gn, ,?fn)) threshold then output(?x owl:sameAs ?y) In fact, this specification says foaf:name - concat(vc:given-name, ,vc:family-name) which is an alignment at the TBox level that can be lifted from the linkage specification. I hope I was clear enough this time ;) Yes you did. Hugh got it right but I was a bit lost ;) My quick take on this issue is usually: Strategy: Use subPropertyOf, etc if possible, otherwise resort to SWRL or SPARQL, otherwise use custom code ( for example, if the IFPs are embedded in URIs ). Implementation: Stick with inference. If not possible, materialize intermediate graph. Of course the above is not very useful as what you're looking for is real world examples to mine for patterns, generalize, and try to push the knowledge up to the TBox. Good luck, it sounds interesting ;) Thanks, A Cheers, François sameAs is not the best way to align things in the TBox.

Re: Segment RDF on BBC Programmes
Hi, On Thu, May 7, 2009 at 6:42 AM, Yves Raimond yves.raim...@gmail.com wrote: Hello! Wading into this conversation a little late, but feel compelled to comment... I'll be honest, I find these kind of RDFa vs RDF/XML vs A.N. Other Publishing Setup discussions tedious and counter-productive. Different technical approaches will be appropriate in different scenarios (*), so whatever our personal preferences let's not make blanket statements in favour of one approach over another without providing qualifying information for people who may be newer to the field and not have in depth appreciation of the subtleties. One of the great strengths of the Linked Data community has been its pragmatism, and while RDFa may be the pragmatic choice in some situations it won't be in others. I completely agree with Tom here, and find this RDFa vs RDF/XML debate quite tedious. For example, in our programmes pages (e.g. http://www.bbc.co.uk/programmes/b00k6mpd) we don't expose all the available versions (signed, shortened, original, etc.) because it is not directly relevant for human consumption - we just merge different things version-related that are relevant (e.g. on-demand audio/video, etc.) to provide a good user experience. So if we were to use only RDFa, we would loose that valuable bit of information. Some data needs to be prodded and merged to not overload the user with information and just present him with bits relevant to human consumption. However, in the raw RDF views, we can provide all these details, that may be relevant for applications, e.g. getting all broadcasts of a signed version of a particular programme. So different publishing methodologies are appropriate for different needs :-) Cheers, y Agree here. In fact, let me say that my own RDFavoritisms have morphed over time as I have run into situations where one approach is better than the other, for any number of reasons. I am doing things now that I once thought to be heresy. I guess the trick is not to argue about what's better/best but to make every possible choice CONSISTENT with the conceptual framework being built, so that every drop of participation adds up and crystallizes. Truth is none of us can foresee which one approach will have the most data 3 years from now. This thing shifts with the winds ( there are more surprises to come, for sure ). Now, what would be useful is a decision tree or a list of recipes. Let newcomers choose but don't overwhelm them with total freedom either. That's the wonder of Linked Data.

Aldo, No argument re. the above, as you know anyhow :-) In more concrete terms. We didn't give M$ a chance to create RDF-MS Edition by staying off the radar. ( I hope so ) Hmm. ADO.NET's Entity Frameworks is RDF-MS salvo #1 Project M is salvo #2. They get it right at #3 and by then it will be them playing well with the Linked Data Web. IE is no doable on the Linked Data Web :-) Ah good examples. Now, regarding IE. Of course it is not the same game so their trick would have been different... But how about Windows Live + Semantic Office + a centralized registry to provide IDs for things. I agree that they will now have to play along with Linked Data web. But they didn't see it coming, if they had... ( well we'll never know I'm just fantasizing here ). Semantic was a great codename, but for the wrong reasons! Great codename for a great Thing. Stinker of a name for discerning meaning of the Thing :-) Semantically correct, but comunicationally impaired ;) Anyway, Semantic Web issues are now water under the bridge in my world view, the big MO is behind Linked Data and we should simply carry this into related and vital realms such as OWL (the TBox side is very important), but do so with pragmatism and coherence. We know this works, based on the Linked Data journey experience. This community has succeeded were alternative approaches have failed. We must never forget that when moving forward. Yes I agree, this is old stuff. I was just looking back for a second. There are so many things I never got to say that I sometimes try to slip them in here. I have to admit that regarding the *Macro* TBox aspect I am only now starting to pay attention. My imagination needs some more training to understand where this is going to take us in the mid term. ( I have groked the ABox aspect for 5 years now, but the other one quickly leads me to AI and out of my comfort zone ). This community is amazing ;) I would put all my chips on the table for you anytime now. ( wait... I already am! ) A. Kingsley

Aldo,
Yes. The box
http://www.w3.org/Icons/SW/sw-cube.{svg,png,giv}
can be used as you describe. If put into a composition but it is clearly
recognizable, I do not see any issue with that either. A good example is
the logo used by RPI:
http://tw.rpi.edu/wiki/Main_Page
(They actually went out of their way by creating an image map, so that
the box links to the W3C site, whereas other parts of the logo links to
RPI...)
OK Great ;)
'Distortion' is not listed on the logo page and, I presume, this might
be a borderline. I could apply strong distortion that would make the
logo barely recognizable, and I think W3C might have an issue with that.
But mild distortion (ie, slight change in scale factors) should be fine.
If you really want to apply such distortion, you may want to check with
W3C first.
I can't remember now, but I am sure there are some distorted versions
out there in the wild. In particular I remember one with a twirl.
In a dogfood manner, is there an RDF vocabulary to describe such
relations? ( derived from ).
It would be useful if the W3C demanded the generated logos to be
RDF-linked to the page via a wiki for example.
Well, that's too much of a stretch, but I think this is not too crazy
an idea: Dogfood, show benefits (right on the page via a dynamic link)
and save some work W3C work patrolling for logos.
This is also in line with CC and, perhaps, even Open Data licensing, etc.
Cheers
Ivan

PS. I said derivatives. The D word... sorry for that ;)

Hi all,
Not sure if this is the place for this, but I believe it is common concern.
I have seen several projects using tweaks (color, distortion,
composition) of the Semantic Web box logo. After reading the
policies I believe that this is allowed as long as there is no W3C
logo involved.
http://www.w3.org/2007/10/sw-logos.html
Is this correct? Can I create such modifiied derivatives from the
clean box logo w/o running into any problems?
Composition is the border case as the logo is unmodified and
recognizable, therefore legally troublesome.
My 2 cents is that they should allow anything as long as you strip
the W3C part.

Re: Pubs data
Hi All, My compliments to John on the Facebook Thread. That's a scary sight! I think the solution to this problem will probably come with Web of Trust and Identity. First off, the thought that I might someday be on the other side, fighting against an unfounded review, makes me think about the following twice. OTOH, We will always have people trying to silence free speech, as it the line is blurry by nature. I can even write something possitive that, taken out of context, seems negative. We need both: control and freedom. How can that be achieved? Let me touch on one possible extremist scenario. Remember Freenet? ( http://freenetproject.org/ ) They go to the extreme of blurring the identity of the author and physical location of bits of information. This pretty much prevents censorship from being applied ( even when it is right to do so ). Now, I wonder if RDF as is might be used to build something like this using P2P architectures, or simple mirrors, or bots. It seems that from a tech POV it would be easy since the only thing moving around is the bit of data. Of course this is not a solution either. We do want control to be applicable. The ideal solution is more in the lines of: 1) Attach identity to the review ( so people take responsibility for what they say ). Free speech as in freedom, not in free 2) Provide voting mechanisms that also attach identity 3) This makes a review more or less discoverable by whoever consumes the service Just throwing in some elements into the discussion Thanks, A On Fri, Mar 6, 2009 at 11:38 AM, John Goodwin john.good...@ordnancesurvey.co.uk wrote: Thanks Tom.

Granular dereferencing ( prop by prop ) using REST + LinkedData; Ideas?
Hi All,
I am in the process of LODing a dataset in which certain properties
are generated on the fly ( props derived from aggregate calculations
over the dataset, remote calls, etc ). I would like to let the clients
choose which of these expensive properties they need on demand and on
a granular level.
For example, lets say I am interested in knowing more about resource
http://ex.com/a.
Per LD conventions, dereferencing http://ex.com/a ( via 303 ) returns
http://ex.com/a a ex:Thing ;
rdfs:label a sample dynamic resource;
ex:dynamic1 45567 .
The problem is that the value for ex:dynamic1 is very expensive to
compute. Therefore, I would like to partition the document in such a
way that the client can ask for the property on a lazy, deferred
manner ( a second call in the future ).
The same is true for dynamic2, dynamic3, dynamic4, etc. All should be
retrievable independently and on demand.
* I am aware that this can be achieved by extending SPARQL in some
toolkits. But I need LOD.
* I am also aware that most solutions require us to break URI
obscurity by stuffing the subject and predicate in the uri for a doc.
* Finally, seeAlso is too broad as it doesn't convey the information I need.
Anyone came up with a clean pattern for this?
Ideas?
Something as simple as:
GET http://x.com/sp?s={subject}p={predicate} --- required RDF
works for me... but... .
If possible, I would like to break conventions in a conventional manner ;)
Best,
A

Hi All,
I am in the process of LODing a dataset in which certain properties
are generated on the fly ( props derived from aggregate calculations
over the dataset, remote calls, etc ). I would like to let the clients
choose which of these expensive properties they need on demand and on
a granular level.
For example, lets say I am interested in knowing more about resource
http://ex.com/a.
Per LD conventions, dereferencing http://ex.com/a ( via 303 ) returns
http://ex.com/a a ex:Thing ;
rdfs:label a sample dynamic resource;
ex:dynamic1 45567 .
The problem is that the value for ex:dynamic1 is very expensive to
compute. Therefore, I would like to partition the document in such a
way that the client can ask for the property on a lazy, deferred
manner ( a second call in the future ).
The same is true for dynamic2, dynamic3, dynamic4, etc. All should be
retrievable independently and on demand.
* I am aware that this can be achieved by extending SPARQL in some
toolkits. But I need LOD.
* I am also aware that most solutions require us to break URI
obscurity by stuffing the subject and predicate in the uri for a doc.
* Finally, seeAlso is too broad as it doesn't convey the information I need.
Anyone came up with a clean pattern for this?
Ideas?
Something as simple as:
GET http://x.com/sp?s={subject}p={predicate} --- required RDF
works for me... but... .
If possible, I would like to break conventions in a conventional manner ;)
Best,
A

Re: Can we afford to offer SPARQL endpoints when we are successful? (Was linked data hosted somewhere)
One clarification, I am not saying that this discussion is not interesting. We still need to figure many things out and they will rise through debate. It's just that this is the public-lod list and lod enthusiasts arrive here. One read of a discussion like this one and off they go. Should we segment this more? lod-dev vs lod-users? Many times I have hit a wall after having a customer of mine reading someone from the SW lists arguing that there is something not right about SPARQL, or RDF, or etc... And he is an authoritative figure. Take a look at Java conferences or Adobe MAX. How many times do these guys question their decisions in public? NONE. Because they know it is suicide to do so. The dynamic that follows is more or less this: If XXX has room for doubts about tech YYY, and he knows so much more than I do, then... why bother?

Ian, After 10 years of debate the SW is finally giving birth to something concrete or tangible. I made reference to the concrete/abstract equation. If this is public-lod, then let's create a users-lod and a dev-lod, and let one stabilize. Please, I am on the sales side and have been for years. Java is easy to sell because you are talking low level details of APIs, not macro business models. ( ok, you can say that standardizing the content repository api has a business impact for day software, but its does not reshape the IT industry ). I agree on the debate, all I am saying is that there should be some stability at the edge. This thread was originated when an apparent newcomer asked for a way to use LOD ( which is what we all want to the world to start asking for! ). And look into what it turned. Let's send a customer satisfaction survey and see how he now feels about this ;) ( joke ). Just pointing that out. I was involved in both Java and flex from the beginning. In fact, the very early days of flex, and have followed the process with attention, contributing my grain of sand when possible. I am tech savvy a salesman. I operate on that front.

Re: Can we afford to offer SPARQL endpoints when we are successful? (Was linked data hosted somewhere)
Hugh, Let's just look forward. This is not the same world, not the same game and definitely not the same problem. The comparison stops the minute you realize we now have billions of computers connected, and a globally distributed DSN. The trick is understanding that we are not exposing SQL endpoints, standing on the shore and throwing stones at the ocean hoping to fill it up. We are throwing powder jelly that will create solid land over which we will be able to walk very soon. What we are doing is assembling ONE big database, because we have ONE namespace that meshes everything ( thanks to the URIs ) and one transport mechanism. And the force that will drive us to open data is economic. Your database contains facts that complement my records and we both benefit from the mutual exchange, and this happens more efficiently in an unplanned manner. Serendipity and unplanned knowledge generation. So, if you consider the URI and the WWW, the comparison between SPARQL and SQL and Databases is not enough. However, I admit it is fair and sometimes necessary at a micro-level. The tech details will be solved in a snap. As you can see from Kingsley's response, this is not a new problem, but rather a new opportunity. I guess the question is: Why would anyone open up their data before? when the integration had to be done manually...

Re: Drilling into the LOD Cloud
Hummm, sorry. When talking about classes it does make sense ;) Or even skos:concepts ( which we can declared to belong to a given vocab, for example ). ( have been working with instance data for too long ). This might call for a way to make statements about a specific IRI, but that would require tertiary relations or some syntactic convention... sounds like going the wrong way. But no worse than the inferencing complexity that would arise from discarding owl:sameAs as a simple conceptual bridge between vocabularies. Sounds like a prob indeed.

The default is: it's not safe (obviously). :x equivalentClass :y - safe when used as a class (e.g. rdf:type :x) :x sameAs :y - always safe (watch out!) :x sameConceptAs :y - safe in subject positions do you mean subject in the 'topic, dc:subject' sense, rather than subject/predicate/object sense? On first reading I thought you meant the latter, which would be problematic since any inverse of property can flip values into 'object' role. So assuming the former, I quite agree. Also thanks for expanding on what I meant. I was indeed picking a strong example to emphasise my (under articulated) case. Using an owl:sameAs claim between independently developed classes and properties is almost always misleading, confusing and untrue. So yup I agree that application-specific properties such as these are often more useful. Also btw folks there is no such thing as dc:author. It was changed in the mid-late 1990s to be dc:creator, so as to better cover non-written creations such as images, museum artifacts etc. So best to avoid/fix it in mail threads before 'dc:author' ends up getting mentioned in books etc. Oops. Made a quick search and I don't use author anywhere in my codebase ( I use creator ). But for some reason it is still sticking in my mind ( band, music, author ) If it shows up in a book I'll feel really guilty, as the material author of that crime ( or should I say creator )...

Lenses. Lists. Facets. Free text search. IFP to IRI resolution. Find documents that contain IRIs etc... They are all implemented in different ways but tend to share semantics across different browsers and services. How far are we from defining a modular framework so we can mix and math these as atomic interaction pieces? Both services and probably UI parts. Of course, RDF and HTTP can be used to describe them and deliver the descriptions and, in the case of widgets, some OOTB implementations. XForms, Dojo widgets, SWFs? I have done something similar but much simpler in a Flex platform ( I serve Flex modules, described in RDF and referenced by Fresnel vocabs, but only for presentation ). And then on a functional side I have several services that do different things, and I can hot swap them. For example, the free text search service is a (S)WS. Faceter service idem. I guess we still need to see some more diversity to derive a taxonomy and start working on the framework. But it is nice to keep this in sight. The recurring topics. Best, A Aldo, Really nice to see you are looking at things holistically. I showed up with a narrow interface, I know ;) As you can see, we are veering gradually towards recognizing that the Web, courtesy of HTTP, gives us a really interesting infrasructure for the time-tested MVC pattern (I've been trying to bring attention to this aspect of the Web for a while now). If you look at ODE (closely) you will notice it's an MVC vessel. We have components for Data Access (RDFiztion Cartridges), components for UI (xslt+css templates and fresnel+xslt+css templates), and components for actions (*Cartridges not released yet*). Ah... I remember telling Daniel Lewis something was missing from his UPnP diagram: a way to modify the Model. aka: a Controller / Actions. You are right, technically an agent like ODE ( assuming you can hook in actions ) is all that you need to allow users to interact with linked data. Let's say that this sort of solution can cover 80% of user interaction cases ( launching simple actions and direct manipulation of resources ), and operates on top of 80% of data ( anything that can be published as linked data/SPARQL and fits within the expressiveness of RDF's abstract model ). Not a bad MVC structure at all! So, how do you plan on hooking up the actions to the shell, is this in the cartridges? How will they surface. Context menu? We've tried to focus on the foundation infrastructure that uses HTTP for the messaging across M-V-C so that you get: M--http-V---http---C Unfortunately, our focus on the MC doesn't permeate. Instead, we find all focus coming at us from the V part where we've released minimal templates with hope that 3rd parties will eventually focus on Display Cartridges (via Fresnel, XSLT+SPARQL, xml+xslt+css, etc..). Well. The M part is the data, isn't it? ( so it is permeating, people are publishing data ). Unless you mean building some higher functionality services ( on top of SPARQL and RDF ) such as faceters, free text search, IFP resolution, etc. But in that case it is also moving forward, although not with a standardized interface. This could be thought of as higher level Data Access components. The C part... that's another story. As I pointed out before, you need to define the way and an environment to hook in the actions. What is the shell? For example, you could provide a JS API for ODE where developers could hook up methods using Adenine like signatures ( which, if I remember correctly, use rdf:type hinting ) and then surface them on the context menu. Or perhaps a server side registry of actions is more suitable. Many options here. I am curious about the Action Cartridges. Best solution overall should be agent independent ( and here we go down the SWS road once again ). btw - David Schwabe [1] also alluded to the architectural modularity that I am fundamentally trying to bring to broader attention in this evolving conversation re. Linked oriented Web applications. The ultimate goal is to deliver a set of options that enable Web Users to Explore the Web coherently and productively (imho). And that will eventually be ( dynamically ) assembled to deliver the functionality that today is present in walled garden applications. Humans can only do so much, and likewise Machines, put both together and we fashion a recipe for real collective intelligence (beyond the buzzword). We desperately need to tap into collective intelligenceen route to solving many of the real problems facing the world today. The Web should make seeing and connecting the dots easier, but this is down to the MVC combo as opposed to any single component of the pattern :-) Aha
SW Marketing: Effective Sales Pitch for VCs and Non-Geeks in General

I was referring directly to my girlfriend, who has had the patience to listen to my ramblings on the semantic web over and over again. Of course the generalization is totally out of line.

Hi All, Hopefully more and more of you are meeting up with VCs or selling internal projects using semantic web technologies. I sold my first RDF based project 5 or 6 years ago and lately I have had some tough VC/fund raising presentations. I realized that I have definitely improved my sales pitch over the years, so I thought I would share some brief thoughts with you guys and hopefully get some feedback and novel ideas. My current approach when selling a project that includes Semantic Web ( specifically Linked Data ) technology is simple. I only use only TWO slides to talk about Semantic Web per-se: 1) I replaced the web layer cake for this slide[1] 2) Then I jump to the LOD cloud diagram by Richard Cyganiak[2]. I emphasize on the size of the datasets and how this is something that has never happened before. 3) That's it. No more semweb talk. Focus on the value proposition and answer questions as they appear. The other useful diagram I have found useful is Nova Spivack's web evolution timeline[3] ( very buzz friendly ). The problem with that particular diagram is that it imposes an abritrary classification (1.0, 2.0, 3.0 ) and you will most probably run into some friction. So... I am sure lots of you have learned and mastered their own sales pitch... What is yours? Any new diagrams that I don't know of? And two suggestions: 1) I think Mr Cyganiak's diagram could use some numbers ( how many records are there in this giant database? ) 2) We could setup a space devoted to marketing. Maybe in some of the community wikis ( does this exist already? ) And don't tell me that marketing is not important. This whole Linked Data / SW re-branding has really made some noise.
