 Co-located with 25th International World Wide Web Conference
April 11 to 15, 2016 in Montreal, Canada


   http://events.linkeddata.org/ldow2016/



The Web is developing from a medium for publishing textual documents
into a medium for sharing structured data. This trend is fueled on the
one hand by the adoption of the Linked Data principles by a growing
number of data providers. On the other hand, large numbers of websites
have started to semantically mark up the content of their HTML pages and
thus also contribute to the wealth of structured data available on the Web.

The 9th Workshop on Linked Data on the Web (LDOW2016) aims to stimulate
discussion and further research into the challenges of publishing,
consuming, and integrating structured data from the Web as well as
mining knowledge from the global Web of Data. The special focus of
this year’s LDOW workshop will be Web Data Quality Assessment and Web
Data Cleansing.

Last CfP BISE Journal special issue on "Linked Data in Business"

[Sören Auer]

Dear all,

I would like point your attention again to the BISE Journal special
issue on "Linked Data in Business":

There is a common misunderstanding concerning enterprise data – linked
not necessarily means open. Internal company data linked to open data
can still be private. This way enterprises gain additional value by
extension, enhancements and verification of own data against external
sources. In this special issue on “Linked Data in Business” we would
like to focus on research that studies the exploitation of linked data
in business, economics and management. Enterprises can integrate data
and discover new insights more easily and this can lead to the emergence
of new products and services.  They will also be able to solve business
challenges in new ways. For this to come true the linked data
exploration seems to be the next big step. Through the integration of
private data and linked open data as well as through the combination of
structured and originally unstructured data added-value chains can be
established.

In the context of the above, the following topics are of special interest:
* data extraction, mapping, publishing and linking methods
* data cataloguing
* datasets retrieval
* language technologies for linked data
* business vocabularies
* geographical linked data
* enterprise data integration
* linked data mining and analytics

For details please visit: http://www.bise-journal.com/?p=974

Submission deadline is *1 November 2015*

Schedule:
* Paper submission deadline:1-11-2015
* Author notification:  10-1-2016
* Revision due: 28-2-2016
* Second revision:  23-5-2016
* Planned publication:  October 2016

Fellowships for PostDocs from developing countries

[Sören Auer]

Dear all,

German Humboldt foundation is sponsoring fellowships for post-doctoral
researchers from developing countries [1]:

http://www.humboldt-foundation.de/georgforster

The topics pursued during such a fellowship should also be of relevance
to the future development of the fellows country of origin.

I think Linked Data and semantic technologies have the potential to
address societal challenges (in developing countries).

If you are or know someone from a developing country working on (or
interested in) a topic of relevance for development, please point him to
the announcement! We and I'm sure also many other German Semantic Web
research groups would be happy to host such fellows.

Re: UNMOOC on Web Science to start!

[Sören Auer]

Steffen, all,

I agree Wikiversity is an interesting platform and of course its great
you started this project there. However, reuse is also one of the main
rationale of SlideWiki:

* all content published in SlideWiki has exactly the same licensing
conditions as in Wikipedia (hence its easy to reuse content on either of
the two platforms)

* in SlideWiki, we optimized the CourseWare content representation for
both presence courses held by a teacher and individual online/offline
learning even from mobile devices

* the SlideWiki content is highly-structured - a course is actually a
tree of sub modules and individual slides and self-assessment questions,
which can be easily reused and repurposed

* SlideWiki also aims to facilitate the multi-lingual reuse, by offering
semiautomated and crowdsourced translation support and facilities for
syncing different language editions of the same course

There are still many issues and things around SlideWiki we want to add
and improve and everyone is invited to get involved - its completely
open-source and open-content.

Great to see more open courseware initiatives such as UNMOOC. I think
the availability and accessibility of qualitative, multilingual open
courseware is still a major issue.

Best,

Sören

 Dear Sören,
 
 thanks for your pointer! This is  very interesting!
 
 However, we favor a slightly different approach.
 We are interested in facilitating reuse beyond the creation of material
 for a course,
 hence our contents are put into the the wikimedia foundation space
 where they are also easily available, e.g., for Wikipedia (where
 appropriate).
 
 For instance, the wikipedia entry
 https://en.wikipedia.org/wiki/Ethernet_frame now reuses our video
 https://commons.wikimedia.org/w/index.php?title=File%3AHow_to_build_an_Ethernet_Frame.webm
 
 which is part of our course
 https://en.wikiversity.org/wiki/Topic:Web_Science/Part1:_Foundations_of_the_web/Internet_Architecture/Ethernet/Ethernet_Header
 
 
 This has already (at this very early stage) generated useful feedback from
 people that would never have considered to look at course material
 and it reaches an audience that would otherwise not benefit
 from our course material.
 
 Cheers,
 Steffen

 Dear Steffen, all,

 This seems to be indeed a very interesting endeavor. In particular the
 creation of open and evolving content with interactive,
 community-oriented feedback sessions seems an interesting concept. Have
 you seen our OpenCOurseWare authoring platform SlideWiki
 http://slidewiki.org - its now open-source, used with dozens of courses,
 several hundred students. There are btw. also comprehensive lecture
 series on Semantic Web, Information Retrieval, Intelligent Systems. The
 Semantic Web lecture (700 slides, 100 self-assessment questions) is
 available in 12 languages (Thai, French Portuguese, Spanish, Italian,
 Hindi, Greek, Persian, Arabic, Russian, German, English). We are really
 interested to build a larger user/author communities around SlideWiki
 content and any ideas in that regard are highly appreciated.

 A MOOC is an online course aimed at large-scale interactive

 Usual MOOCs combine canned content (text, videos, etc.) with
 interactive, community-oriented feedback sessions.
 In contrast, our unusual MOOC targets the creation of open and evolving

 There are three models for certification
 1. Joining exams in Koblenz and earning ECTS credits
 2. Examination by an outside institution.

Re: Semantic Web content management systems, written in PHP

[Sören Auer]

Christoph,

That's exactly a usecase of OntoWiki (http://ontowiki.net). We use
OntoWiki as a CMS for example on http://lod2.eu, http://aksw.org,
http://geoknow.eu
These are driven by the site extension for OntoWiki.

You can either install the OntoWiki+Virtuoso open-source versions alone,
install the complete LOD2 Stack (where both are included along with lots
of other useful Linked Data tools [1] or obtain an enterprise grade
commercially supported version from our partner company Eccenca.com

 I'm a student, currently working with the 'Information Systems and

 The final goal is to use our OWL-based ontology
 (http://rz-vm30.gfz-potsdam.de/ontology/isdc_1.4.owl) as a knowledge
 foundation in a content management system, which would enable us to
 enrich available data with Linked Open Data.
 
 Currently we are focussing on evaluating frameworks that are based on
 PHP. So far we tried Drupal with minor success, the only other CMS
 currently on our radar is Ximdex.
 
 Any other suggestions, regarding a Semantic web centered content

ERCIM News No. 96 (January 2014)

DEADLINE: Thursday 21 November 2013

Please read the guidelines below before submitting an article

The sections of ERCIM News 96 are :

  * Joint ERCIM Actions
  * Special theme: *Linked Open Data*
  * *Research and Innovation*
  * Events
  * In Brief

The *Special Theme* and the*Research and Innovation* sections contain
articles presenting a panorama of European research activities. The
Special Theme focuses on a sector which has been selected by the editors
from a short list of currently hot topics whereas the Research and
Innovation section contains articles describing scientific activities,
research results, and technical transfer endeavours in any sector of
ICT, telecommunications or applied mathematics. Submissions to the
Special Theme section are subjected to an external review process
coordinated by invited guest editors whereas submissions to the Research
and Innovation section are checked and approved by the ERCIM News
editorial board.

Special Theme: *Linked Open Data*

Guest editors:

  * Sören Auer: University of Bonn and Fraunhofer IAIS
  * Irini Fundulaki: Institute of Computer Science, FORTH

This ERCIM News special theme invites short articles on new approaches,
achievements and applications in the area of Linked Data. The W3C
Linking Open Data Initiative has boosted the publication and
interlinkage of a large number of datasets on the web resulting in the
emergence of a Web of Data. The dynamic growth of Linked Data stimulates
new research in various areas such as data management, semantic web and
web engineering. In this special issue, we aim to provide an overview on
a wide spectrum of state-of-the-art and newly emerging approaches
related to Linked Data. Technical articles are solicited on topics
related to all stages of the Linked Data management life cycle. Since
the Linked Data principles cannot only be applied to openly published
data on the Web, but also to data published within an organization's
intranet, we also invite contributions regarding the deployment of
Linked Data technologies in Intranet settings.

Topics include but are not limited to:

  * Searching the Web of Data
  * Transformation, mapping and publishing of Linked Data
  * Storage, query processing and optimization for (distributed) RDF
  * Architectures and applications for consuming Linked Data
  * Indexing and crawling the Web of Data
  * Linked Data evolution, enrichment, repair, change management
  * Web Data quality assessment and trustworthiness
  * Linked Data integration (entity resolution, instance and schema
matching)
  * Reasoning on Linked Open Data
  * Benchmarking RDF and graph database engines
  * Linked Data summarization
  * Visualization of Linked Open Data
  * Linked Data applications (e.g. life sciences, enterprise data
integration, digital humanities)
  * Management of Licenses for Linked Open Data

Articles have to be sent to the local editor for your country (see About
ERCIM News http://ercim-news.ercim.eu/about-ercim-news) or to the
central editor peter.k...@ercim.eu mailto:peter.k...@ercim.eu

Reviewing:
Articles submitted to the special theme are subject to a review process.


  Guidelines for ERCIM News articles

*Style:* ERCIM News is read by a large variety of people. Keeping this
in mind the article should be descriptive (emphasize more the 'what'
than the 'how') without too much technical detail together with an
illustration, if possible.

Contributions in ERCIM News are normally presented without formulas. One
can get a long way with careful phrasing, although it is not always wise
to avoid formulas altogether. In cases where authors feel that the use
of formulas is necessary to clarify matters, this should be done in a
separate box (to be treated as an illustration). However, formulas and
symbols scattered through the text must be avoided as much as possible.

*Length:* Keep the article short, i.e. 700-800 words.

*Format:* Submissions preferably in ASCII text or MS Word.
Pictures/Illustrations must be submitted as separate files (not embedded
in a MS Word file) in a resolution/quality suitable for printing.

*Structure of the article:*
The emphasis in ERCIM News is on 'NEWS'. This should be reflected in
both title and lead ('teaser').
Also: NO REVIEW ARTICLES!

  * *Title*
  * *Author *(full name, max. two or three authors)
  * *Teaser:*
a few words about the project/topic. Printed in bold face, this part
is intended to raise interest (keep it short).
  * *Details describing*:
what the project/product is
which institutions are involved

ERCIM News 96 on Linked Open Data - Call for contributions

[Sören Auer]

Call for short article contributions (cf. http://ercim-news.ercim.eu/call)


ERCIM News No. 96 (January 2014)

DEADLINE: Thursday 21 November 2013

Please read the guidelines below before submitting an article

The sections of ERCIM News 96 are :

  * Joint ERCIM Actions
  * Special theme: *Linked Open Data*
  * *Research and Innovation*
  * Events
  * In Brief

The *Special Theme* and the*Research and Innovation* sections contain
articles presenting a panorama of European research activities. The
Special Theme focuses on a sector which has been selected by the editors
from a short list of currently hot topics whereas the Research and
Innovation section contains articles describing scientific activities,
research results, and technical transfer endeavours in any sector of
ICT, telecommunications or applied mathematics. Submissions to the
Special Theme section are subjected to an external review process
coordinated by invited guest editors whereas submissions to the Research
and Innovation section are checked and approved by the ERCIM News
editorial board.

Special Theme: *Linked Open Data*

Guest editors:

  * Sören Auer: University of Bonn and Fraunhofer IAIS
  * Irini Fundulaki: Institute of Computer Science, FORTH

This ERCIM News special theme invites short articles on new approaches,
achievements and applications in the area of Linked Data. The W3C
Linking Open Data Initiative has boosted the publication and
interlinkage of a large number of datasets on the web resulting in the
emergence of a Web of Data. The dynamic growth of Linked Data stimulates
new research in various areas such as data management, semantic web and
web engineering. In this special issue, we aim to provide an overview on
a wide spectrum of state-of-the-art and newly emerging approaches
related to Linked Data. Technical articles are solicited on topics
related to all stages of the Linked Data management life cycle. Since
the Linked Data principles cannot only be applied to openly published
data on the Web, but also to data published within an organization's
intranet, we also invite contributions regarding the deployment of
Linked Data technologies in Intranet settings.

Topics include but are not limited to:

  * Searching the Web of Data
  * Transformation, mapping and publishing of Linked Data
  * Storage, query processing and optimization for (distributed) RDF
  * Architectures and applications for consuming Linked Data
  * Indexing and crawling the Web of Data
  * Linked Data evolution, enrichment, repair, change management
  * Web Data quality assessment and trustworthiness
  * Linked Data integration (entity resolution, instance and schema
matching)
  * Reasoning on Linked Open Data
  * Benchmarking RDF and graph database engines
  * Linked Data summarization
  * Visualization of Linked Open Data
  * Linked Data applications (e.g. life sciences, enterprise data
integration, digital humanities)
  * Management of Licenses for Linked Open Data

Articles have to be sent to the local editor for your country (see About
ERCIM News http://ercim-news.ercim.eu/about-ercim-news) or to the
central editor peter.k...@ercim.eu mailto:peter.k...@ercim.eu

Reviewing:
Articles submitted to the special theme are subject to a review process.


  Guidelines for ERCIM News articles

*Style:* ERCIM News is read by a large variety of people. Keeping this
in mind the article should be descriptive (emphasize more the 'what'
than the 'how') without too much technical detail together with an
illustration, if possible.

Contributions in ERCIM News are normally presented without formulas. One
can get a long way with careful phrasing, although it is not always wise
to avoid formulas altogether. In cases where authors feel that the use
of formulas is necessary to clarify matters, this should be done in a
separate box (to be treated as an illustration). However, formulas and
symbols scattered through the text must be avoided as much as possible.

*Length:* Keep the article short, i.e. 700-800 words.

*Format:* Submissions preferably in ASCII text or MS Word.
Pictures/Illustrations must be submitted as separate files (not embedded
in a MS Word file) in a resolution/quality suitable for printing.

*Structure of the article:*
The emphasis in ERCIM News is on 'NEWS'. This should be reflected in
both title and lead ('teaser').
Also: NO REVIEW ARTICLES!

  * *Title*
  * *Author *(full name, max. two or three authors)
  * *Teaser:*
a few words about the project/topic. Printed in bold face, this part
is intended to raise interest (keep it short).
  * *Details describing*:
what the project/product is
which institutions are involved
where it takes place
why the research is being done
when it was started/completed the aim of the project
the techniques employed
the orientation of the project
future activities
other institutes involved in this project
co-operation with other ERCIM members in this field

 Very nice!
 
 Are you exposing a graph that describes these lecture collections? If
 so, how does one discover it?

Exactly, that's what the graph exhibits - it basically consists of
decks, as well as sub-decks and slides associated with those decks. Each
slide contains the full html source.
Currently, we publish the RDF via slidewiki.org/triplify
As mentioned before, this is still a quick hack currently - we plan to
deploy SparqlMap [1], which will also allow SPARQL querying and will add
proper RDF discovery.

[CfP] 6th Workshop on Linked Data on the Web (LDOW2013)

[Sören Auer]

  Call for Papers: 6th Workshop on Linked Data on the Web (LDOW2013)
 Co-located with 22nd International World Wide Web Conference
14 May 2013, Rio de Janeiro, Brazil
   http://events.linkeddata.org/ldow2013/


Linked Data is a set of best practices for publishing structured data on
the Web which focuses on setting hyperlinks between data items provided
by different web servers. These hyperlinks connect the data from all
servers into a single global data graph - the Web of Linked Data.

The 6th Workshop on Linked Data on the Web (LDOW2013) aims to stimulate
further research into exploiting this global data graph to deliver
transformative applications to large user bases, as well as to mine the
graph for implicit knowledge. Inevitably the challenges associated with
Linked Data range from lower level 'plumbing' issues over large-scale
data processing and mining, to higher level conceptual questions of
value propositions and business models. LDOW2013 will provide a forum
for exposing novel, high quality research and applications in all of
these areas. In addition, by bringing together researchers in the field,
the workshop will further shape the ongoing Linked Data research agenda.

ANN: 3rd PUBLINK Linked Data publishing and tooling support action

[Sören Auer]

Dear all,

After more than a dozen small PUBLINK projects have been graduated in
the last two years [1], we are now launching a third round, which also
includes specific support for Linked Data tool developers, who want to
integrate their tool with the Debian-based LOD2 Stack [2]. The PUBLINK
Linked Open Data Consultancy is backed by the LOD2 project [3].

In order to lower the entrance barrier for potential data publishers and
to improve the integration and interoperation of tools we offer the
*free* PUBLINK Linked Open Data Consultancy to up to five selected
organizations supporting their data publishing or tool integration
projects with an overall effort of 10-20 days each comprising support
from highly skilled Linked Data professionals.

More information about PUBLINK and instructions on how to apply can be
found at:

http://lod2.eu/Article/Publink.html

PUBLINK aims to support Linked Data tool developers as well as
organizations (e.g. governmental agencies, data providers, public
administrations), which are interested to publish large amounts of
structured information of a potentially high public interest.
Brief applications of interested organizations are being accepted till
December 31st 2012.

Please forward this announcement to any potential stakeholders in this
domain you might know.

On behalf of the LOD2 consortium,

Sören

 Dear all,

 As we all know, DBpedia is an important dataset in Linked Data as it is not
 only connected to and from numerous other datasets, but it also is relied
 upon for useful information. However, quality problems are inherent in
 DBpedia be it in terms of incorrectly extracted values or datatype problems
 since it contains information extracted from crowd-sourced content.

 However, not all the data quality problems are automatically detectable.
 Thus, we aim at crowd-sourcing the quality assessment of the dataset. In
 order to perform this assessment, we have developed a tool whereby a user
 can evaluate a random resource by analyzing each triple individually and
 store the results. Therefore, we would like to request you to help us by
 using the tool and evaluating a minimum of 3 resources. Here is the link to
 the tool: http://nl.dbpedia.org:8080/TripleCheckMate/, which also includes
 details on how to use it.

 In order to thank you for your contributions, a lucky winner will win either
 a Samsung Galaxy Tab 2 or an Amazon voucher worth 300 Euro. So, go ahead,
 start evaluating now !! Deadline for submitting your evaluations is 9th
 December, 2012.

Actually LODStats is both, a tool and a service. The open-source tool
(https://github.com/AKSW/LODStats) can be used for analysing anything.
If you are not happy with our selection criteria in the service, you can
run your own LODStats installation, put a crawler in front and analyse
all the datasets you want. Just our service at stats.lod2.eu is a little
selective ;-)

 And
 http://thedatahub.org/dataset/dbpedia-lite
 (Or at least I couldn't find them.)

 I'm not sure you should claim all LOD datasets registered on CKAN

 Depends on the definition of dataset - for me a dataset is something
 available in bulk and not a pointer to a large space of URLs containing
 some data fragments requiring extensive crawling.
 I can't agree with this.
 To rule out Linked Data that only provides Linked Data without SPARQL or 
 dump and say it is not a LOD Dataset seems to be terribly restrictive.

 I would distinguish between Linked Data and a LOD dataset:

 For me (and I would assume most people) /dataset/ means a set of data,
 i.e. a downloadable dump or bulk data access (e.g. via SPARQL) to a data
 repository.

 When the data adheres to the RDF data model and dereferenceable IRIs are
 used its a /Linked Data dataset/.

 When licensed under an open license (according to the open definition)
 its a /Linked Open Data (LOD) dataset/.

 I agree, that /Linked Data/ also comprises individual data resources
 (either independently) or integrated into HTML as RDFa, but I would not
 call these dataset then and also not open (if not licensed according to
 the open definition). BTW: The open definition also requires bulk data
 access! So we have already to reasons, why the concept LOD dataset
 should imply availability of bulk data. This is also, what we mention
 everywhere when describing LODStats.

 When you are interested in statistics about arbitrary Linked Data
 Sindice provides probably the better statistics.

 For example, the eprints (eprints.org) Open Archives have upwards of 100M 
 triples of pretty interesting (to some people) Linked Data.

 Maybe interesting, but if I have to crawl it in order to make use of it
 the burden is way too high for most users.

 It is mostly not in thedatahub, but even if it was you would ignore it.
 In fact, anything that is a wrapper around things like dbpedia, twitter, 
 Facebook, or even Facebook itself is ignored, I am assuming from what you 
 say.

 For DBpedia you don't need a wrapper - the whole dataset is available in
 bulk. All others are from my point of view neither datasets nor open.
 Maybe you can call them data services, where you can obtain an
 individual data item at a time. And why would you want to call a wrapper
 dataset. Fundamental requirements for datasets would be from my point of
 view that you can apply set operations like merging, joining etc. You
 can not do that with wrappers, so why should we call them datasets?

 To publish statistics that claims to collect statistics from all LOD 
 datasets using a method that ignores such resources is to seriously 
 underreport the LOD activity (not a Good Thing), and also is to publish 
 what I can only say is misleading statistical reports about LOD in general.
 I leave aside that you also fail to collect statistics from more than half 
 of the datasets you claim to be collecting.

 I agree, that our figures are quite pessimistic, but in a way, they
 reflect, what people really see -- if there is no link to the dump in
 thedatahub the dataset is difficult to find obviously, if
 confusing/non-standard file extensions or dataset package formats are
 used this makes it also very difficult for people to actually use this
 data. So I think its better, to be a little more pessimistic in this
 case instead of reporting skyrocking numbers all the time.

I understand why Linked Open Numbers is not available as a dump - how
would you package a countable infinite number of resources ;-)

 if you don't have dbpedialite, for example.

Does there exist a dump for dbpedialite - a link to the dump does not
seem to be registered at thedatahub.

i.e. a downloadable dump or bulk data access (e.g. via SPARQL) to a data
repository.

When the data adheres to the RDF data model and dereferenceable IRIs are
used its a /Linked Data dataset/.

When licensed under an open license (according to the open definition)
its a /Linked Open Data (LOD) dataset/.

I agree, that /Linked Data/ also comprises individual data resources
(either independently) or integrated into HTML as RDFa, but I would not
call these dataset then and also not open (if not licensed according to
the open definition). BTW: The open definition also requires bulk data
access! So we have already to reasons, why the concept LOD dataset
should imply availability of bulk data. This is also, what we mention
everywhere when describing LODStats.

When you are interested in statistics about arbitrary Linked Data
Sindice provides probably the better statistics.

 For example, the eprints (eprints.org) Open Archives have upwards of 100M 
 triples of pretty interesting (to some people) Linked Data.

Maybe interesting, but if I have to crawl it in order to make use of it
the burden is way too high for most users.

 It is mostly not in thedatahub, but even if it was you would ignore it.
 In fact, anything that is a wrapper around things like dbpedia, twitter, 
 Facebook, or even Facebook itself is ignored, I am assuming from what you say.

For DBpedia you don't need a wrapper - the whole dataset is available in
bulk. All others are from my point of view neither datasets nor open.
Maybe you can call them data services, where you can obtain an
individual data item at a time. And why would you want to call a wrapper
dataset. Fundamental requirements for datasets would be from my point of
view that you can apply set operations like merging, joining etc. You
can not do that with wrappers, so why should we call them datasets?

 To publish statistics that claims to collect statistics from all LOD 
 datasets using a method that ignores such resources is to seriously 
 underreport the LOD activity (not a Good Thing), and also is to publish what 
 I can only say is misleading statistical reports about LOD in general.
 I leave aside that you also fail to collect statistics from more than half of 
 the datasets you claim to be collecting.

I agree, that our figures are quite pessimistic, but in a way, they
reflect, what people really see -- if there is no link to the dump in
thedatahub the dataset is difficult to find obviously, if
confusing/non-standard file extensions or dataset package formats are
used this makes it also very difficult for people to actually use this
data. So I think its better, to be a little more pessimistic in this
case instead of reporting skyrocking numbers all the time.

 However... is it me, or isn't the 'almost 2B triples' a very
 disappointing number? If you go through all datasets advertised on the
 Data Hub, the advertised number of triples is over 40B ! This means
 that only one out of 20 triples in the linked 'open' data cloud is
 publicly accessible.

It certainly is and this is one of the reasons we developed this tool to
get a better picture of the LOD cloud. Of cause this difference is
partially caused by invalid links in CKAN and some issues we still have
with dealing with very large datasets, but these issues real users might
have as well.

 Another thing... it seems as if LODStats is merely checking whether a
 SPARQL endpoint is 'up' and whether the endpoint actually contains the
 data that has been advertised on the Data Hub. For instance, my very
 own bubble is listed without problems, but I know for a fact that the
 triple store no longer contains the data (sorry!). Do you have any
 thoughts/ideas on how to detect such problems?

We currently don't delete our stats when an endpoint is not available
once, but try to check back later. Of course after a certain number of
check backs and timeouts the stats should be invalidated. Can you point
me to your endpoint and we will have a look what's the problem there.

Best,

[Ann] LODStats - Real-time Data Web Statistics

[Sören Auer]

Dear all,

We are happy to announce the first public *release of LODStats*.

LODStats is a statement-stream-based approach for gathering
comprehensive statistics about datasets adhering to the Resource
Description Framework (RDF). LODStats was implemented in Python and
integrated into the CKAN dataset metadata registry [1]. Thus it helps to
obtain a comprehensive picture of the current state of the Data Web.

More information about LODStats (including its open-source
implementation) is available from:

http://aksw.org/projects/LODStats

A demo installation collecting statistics from all LOD datasets
registered on CKAN is available from:

http://stats.lod2.eu

We would like to thank the AKSW research group [2] and LOD2 project [3]
members for their suggestions. The development LODStats was supported by
the FP7 project LOD2 (GA no. 257943).

On behalf of the LODStats team,

Sören Auer, Jan Demter, Michael Martin, Jens Lehmann

 Very nice! Does it output VoID [1]? Didn't find it skimming the source ...

It does, might not be directly linked yet, but we will add the links soon.
However, not all LODStats staistics can be represented using VoID, which
is why we suggest to add another property to VoID allowing to attach
DataCubes to a VoID descriptions.
You can find the detail in our technical report - would be creat, if
such a property would find its way into the next revision of DataCube ;-)

Thanks for the encouraging comments,

 Congrats, this is awesome.

Thanks Richard, we are happy you like it ;-)

 So you're automatically harvesting 200+ datasets by starting with the LOD 
 Cloud metadata we're collecting on the Data Hub (ex CKAN), leading to a total 
 of almost 2B triples.

Exactly.

 Also fascinating is the list of 250 datasets that couldn't be automatically 
 harvested due to SPARQL errors or errors in the RDF dumps:
 http://stats.lod2.eu/rdfdoc/?errors=1
 This is an excellent interoperability testbed and should be closely studied 
 by anyone who's interested in the state of actual interoperability on the web 
 of linked data (hence a CC to the Pedantic Web Group).

Yes, having an interoperability testbed and a timely view on the current
state was one of the primary reasons for developing LODStats. Some
problems might, however, also be related to incorrect CKAN metadata or
some glitches in LODStats itself - we will try to iron them out as much
as possible in the next weeks.

 One request: on http://stats.lod2.eu/stats it shows top 5 lists of various 
 sorts (top vocabularies, classes, languages etc). Would it be possible to 
 allow drill-down to see longer lists, let's say top 100 or top 1000? These 
 lists are great, but the really interesting stuff often happens in the 
 midfield.

Indeed, thats a great suggestion and will be implemented soon.

 I see VoID summaries for each individual dataset. Are they aggregated 
 somewhere into a single file that I could SPARQL?

Not yet, but that's planned. For now it should be relatively easy to
crawl and concat the VoID files, but we will make it more convenient ;-)

 Also, how do I cite your work in publications? Is there a paper (or at least 
 tech report) yet?

We submitted a paper, which you can cite:

Jan Demter, Sören Auer, Michael Martin, Jens Lehmann: LODStats – An
Extensible Framework for High-performance Dataset Analytics, submitted
to ESWC2012

Re: [Ann] LODStats - Real-time Data Web Statistics

Richard,

These are all great suggestions, which we will try to implement in the
next days.
The LODSTats logo in the header was supposed to serve as a link to the
About page (http://aksw.org/projects/LODStats
), but I guess we should place that more prominently.

Thanks for your valuable feedback,

 One more thing. Can I search for the stats for a particular datasets somehow?
 
 Let's say I want to see the stats for the prefix-cc dataset (or rather, check 
 if LODStats was able to produce stats at all or whether there was an error). 
 Looks like currently I have to manually page through all packages to find it.
 
 Hacking the URL also doesn't work as you're not using Data Hub IDs in your 
 URLs but your own numeric identifiers for the datasets.
 
 It would be great if you had URLs like stats.lod2.eu/rdfdoc/view/prefix-cc as 
 redirects/aliases for http://stats.lod2.eu/rdfdoc/view/119 because that would 
 make it possible to link to this statistics page from other places, like 
 directly from CKAN, or from an alternative version of the LOD Cloud diagram 
 that colors datasets according to their interoperability.
 
 Finally, the stats.lod2.eu site lacks an About page that explains the purpose 
 of the site, sketches the process that is used to generate the stats, states 
 the authors/credits, and states where I'm supposed to send my feature 
 requests ;-)

SEMANTIC WEB TRACK

One of the biggest challenges in Computer Science is the exploitation of
the Web as a global platform for data and information integration as
well as for intelligent search and querying. Semantic Web technologies
and particularly the Linked Data paradigm have evolved as powerful
enablers for the enrichment of the current document-oriented Web with a
Web of interlinked data and, ultimately, a the Semantic Web. To
facilitate this transition many aspects of distributed data and
information management need to be adapted, advanced and integrated.


TOPICS

We invite original contributions on topics related to the Semantic Web,
including (but not limited to):

* Linked Data on the Web as well as in the enterprise
* RDF stores and repositories
* RDF data publishing and access
* Querying and searching Semantic Web Data, including combinations with
  statistics, natural language, soft computing and distributed
  approaches
* Methods for linking, integrating and federating Data on the Web
* Semantic annotation and metadata
* Community and social mechanisms for the definition of semantics of
  data, and metadata and ontology creation
* Ontologies, Reasoning and representation languages (such as OWL), as
  they pertain to Web needs
* Re-purposing of data, information, and multimedia using semantics
* Applications of Semantic Web formats for enterprises, learning and
  science
* Other novel applications that exploit structured Web data sources
* Blogs, wikis, browsers, crawlers, harvesters, content management
  systems, search engines and other applications that produce and
  consume Semantic Web Data
* Mobile and ubiquitous applications exploiting semantics
* User interfaces for interacting with Semantic Web Data
* Methodologies for the engineering of Semantic Web applications

[Ann] First public release of the LOD2 Stack

[Sören Auer]

Dear all,

The LOD2 consortium [1] is happy to announce the first release of the
LOD2 stack available at: http://stack.lod2.eu

The LOD2 stack is an integrated distribution of aligned tools which
support the life-cycle of Linked Data from extraction, authoring over
enrichment, interlinking, fusing to visualization. The stack comprises
new and substantially extended tools from LOD2 members and 3rd parties.
The LOD2 stack is organized as a Debian package repository making the
tool stack easy to install on any Debian-based system (e.g. Ubuntu).

A quick look at the stack and its components is available via the online
demo at: http://demo.lod2.eu/lod2demo

For more thorough experimentation a virtual machine image (VMware or
VirtualBox) with pre-installed LOD2 Stack can be downloaded from:
http://stack.lod2.eu/VirtualMachines/

More details and the instructions on installing the LOD2 Stack locally
are available in the HOWTO Start document [2]. This first release of the
LOD2 stack contains the following components:

   * LOD2 demonstrator, the root package (TenForce/LOD2)
   * Virtuoso, RDF storage and data management platform (Openlink)
   * OntoWiki, semantic data wiki authoring tool (ULEI)
   * SigmaEE, multi-source exploration tool (DERI)
   * D2R, RDF wrapper for SQL databases (FUB)
   * Silk, interlinking engine (FUB)
   * ORE, ontology repair and enrichment toolkit (ULEI)

PoolParty (taxonomy manager by SWCG), Spotlight (annotating texts wrt.
DBpedia by FUB) and CKAN/thedatahub.org were integrated as online
services. A selection of datasets has been packaged and is available in
the LOD2 Stack repository.

The LOD2 stack is an open platform for Linked Data components. We are
happy to welcome new components. Detailed instructions how to integrate
your component into the LOD2 Stack as Debian package are available in
the HOWTO Contribute [3]. From now on we will regularly release improved
and extended versions of the LOD2 Stack. Major releases are expected for
Fall 2012 and 2013. For assistance or any questions related to the
LOD2-stack contact support-st...@lod2.eu

Special thanks for their substantial contributions to this release go to
Bert van Nuffelen, Sebastian Tramp, Robert Isele, Hugh Williams, and
Jens Lehmann.

[Ann] Indian-summer school on Linked Data (ISSLOD 2011)

[Sören Auer]

  *Indian-Summer School on Linked Data*
Leipzig, Sep 12-18, 2011
 http://isslod.lod2.eu/

ISSLOD takes place in late summer with hopefully still a lot of Indian
Summer (i.e. Altweibersommer / Бабье лето) sunshine rays.

The Linked Data methodology is a light-weight approach to facilitate the
transition from the document Web to the Web of Data and ultimately a
Semantic Web. With a wide availability of Linked Data tools and
knowledge bases, a steadily growing RD community, industrial
applications, the Linked Data paradigm already became crucial building
block of the Web architecture.

ISSLOD is primarily intended for postgraduate (PhD or MSc) students,
postdocs, and other young researchers investigating aspects related to
the Semantic Data Web. The Summer School will also be open to senior
researchers wishing to learn about Semantic Web issues related to their
own fields of research.

For further details please visit: http://isslod.lod2.eu

ISSLOD is organized by the EU-FP7 project LOD2 - Creating Knowledge out
of Interlinked Data. Lecturers comprise distinguished experts from LOD2
member organizations as well as invited speakers, the majority of which
will - apart from their lectures - also be present for the duration of
the school to interact with students. Interaction with senior
researchers and establishing contacts within young researchers is a main
focus of the school, which will be supported through social activities
and an interactive, amicable atmosphere.

   ISSLOD Application Deadline: 30 July 2011
   Notifications:5 August 2011
   ISSLOD:   12-18 September 2011

There will be a limited number of student grants available. Details of
the registration process will be announced on the Web site, after the
application deadline. We will keep the registration fee low (175 EUR)
and provide reasonable accommodation packages (less than 40 EUR per
night) for students.

Can anyone recommend software to stand up a simple linked data browser
for a demonstration system we plan on hacking together next week?
What we need is something very simple, much like the the code that
produces the HTML for http://dbpedia.org/page/Baltimore.


The code behind the DBpedia resource pages is based on Disco:

http://www4.wiwiss.fu-berlin.de/bizer/ng4j/disco/

If you want something a little less puristic you might also try OntoWiki:

http://ontowiki.net/

It has a class-hierarchy browser, faceted-browsing, map views, 
customized views as well as various filter options built in. It allso 
supports the full range of LOD best-practices from content-negotiation, 
over SPARQL endpoint, Semantic Pingback to OpenID and FOAF+SSL.

CfP: Position Papers for Linked Data Session at Future Internet Assembly

[Sören Auer]

  Linked Data session at the Future Internet Assembly (FIA)

  16th of December, Ghent, Belgium

http://semanticweb.org/wiki/LinkedDataFIA2010 (this call)
http://www.fi-ghent.eu(the FIA in Ghent event)
http://www.future-internet.eu (the general initiative)


Short position papers (1-10 pages LNCS) are due on *30th November 2010*
(Although appreciated authors are *not* required to attend the event.)


The Future Internet sparked the interest of many different communities. 
All of these communities develop specific parts of infrastructure, which 
at one point of time need to be able to interoperate. Unfortunately, 
currently the Future Internet architecture does not include means to 
achieve interoperability at a data level. At the same time Linked Data 
is becoming an accepted best practice to exchange information in an 
interoperable and reusable fashion. Many different communities on the 
Internet use Linked Data standards to provide and exchange interoperable 
information. This is strikingly confirmed by the dramatically growing 
Linked Data cloud and the currently more than 25 billion facts 
represented and interconnected therein with exponential growth rates 
both in terms of data sets and contained data.


The OSI/OSI 7-Layer architecture is a conceptual view on networking 
architectures. One possible view is a look at Linked Data as an 
independent layer in the Internet architecture, on top of the networking 
layer, but below the application layers, since it provides a common data 
model for all applications as shown in the figure below. This session 
investigates this view, what implications this imposes on the Future 
Internet Architecture, but also how future architectures and system 
developments can benefit from this new layer.


We are looking for position papers regarding the use of Linked Data in 
the Future Internet. These can be either concrete current use-cases or 
envisioned usages for the topics relevant for the Future Internet 
(examples include: Internet of Things, embedded systems, FIRE, services, 
smart cities., Open Government Data, Future Internet Architecture and 
others). The papers provide an input for the ongoing discussion on the 
role of Linked Data for the Future Internet.



*Submission*

Your position paper should have between 1 and 10 pages. We encourage 
authors to comply with the Springer LNCS format.


Position papers can be submitted until 30th November 2010 (in HTML or 
PDF) via email to futureinter...@semanticweb.org.



*Selection*

The session’s organizers reserve the right to do a relevance check of 
submitted position papers and reject papers, which are clearly not 
relevant to the topic outlined above.



*Publication*

Submitted position papers will be published on a website related to the 
Future Internet Assembly Linked Data Session and may influence further 
developments in the Future Internet space.

But is not working with any breadth of such providers.

I share Georgi's reservations, seems like an odd direction for EU
framework projects to take.


Its not really a fundamental change of direction, our main focus is 
research but we also want to evaluate our results on real data and give 
something back to the citizens, which is why we aim to get in touch 
with data owners of high public interest and help them a little to move 
in the right (i.e. LOD) direction ;-)


If commercial linked data service providers beyond LOD2/LATC consortia, 
want to get involved in PUBLINK we are more than happy about that. Let 
me know if you have suggestions how this could be implemented best.


Sören

PS: Please also keep in mind that PUBLINK is very limited (max. 3-5 data 
owning organizations) and ca. 10 man days of support for each.

Ann: PUBLINK Linked Data Consultancy

[Sören Auer]

Dear all,

We are pleased to announce the PUBLINK Linked Open Data Consultancy 
backed by the consortia of the EU-FP7 LOD2 [1] and LATC projects [2].


In order to lower the entrance barrier for potential data publishers the 
LOD2 and LATC consortia offer the *free* PUBLINK Linked Open Data 
Consultancy to up to five selected organizations supporting them with 
the publishing of Linked Open Data with an overall effort of 10-20 days 
each comprising support from highly skilled Linked Data professionals.


More information about PUBLINK can be found at:

http://lod2.eu/Article/Publink.html

With PUBLINK we aim to particularly support organizations (such as 
governmental agencies, commercial data providers, public 
administrations), which are interested to publish large amounts of 
structured information of a potentially high public interest. 
Applications of interested organizations are being accepted till 
December 20th.


Please forward this announcement to any potential stakeholders in this 
domain you might know.


On behalf of the LOD2 and LATC consortia,

Sören

So, now the EU also takes that burden off the small linked data

Not at all! PUBLINK is not aimed at organizations which already 
precisely know what they want and are willing to pay for it.


It is more aimed at people in organizations who want to persuade their 
decision makers or decision makers who need more information or a 
showcase in order to get ultimately involved.


Insofar PUBLINK rather clears the way for commercial linked data service 
providers.

GI INFORMATIK 2010 Workshop on Web Science

[Sören Auer]

**Apologies if you receive multiple copies of this CFP**


==INFORMATIK 2010 Workshop on Web Science==
co-located with GI-Jahrestagung 2010

http://aksw.org/WebScienceWorkshop

Web science is often referred to as the science of decentralized 
information systems.
While novel technologies such as semantic web, web services, and cloud 
computing are germane to the broad proliferation of Web technologies, we 
also need to understand phenomena of the Web in the small as well as in 
the large, in order to retain its usefulness and benefit to people. This 
is in the center of attention of Web science and includes besides the 
mentioned technological approaches, research related to online 
communities, information diffusion on the Web, Web governance, global 
network structures beyond the individual communities on the Web, growth 
analysis, incentive and monetization systems.


This workshop provides a platform for researchers and practitioners to 
exchange preliminary results, new concepts and methodologies in this area.


===Topics of interest ===

* Web Governance incl. Provenance, Licensing, Data Security, Access
  Control
* Open Knowledge ecosystems on the Web, such as Open Governmental Data,
  Open Scientific Data
* Information quality assessment
* Quality, coherence and user interaction on the Linked Data Web
* Social computing applications such as collaborative filtering,
  community-based information retrieval and recommendation,
  collaborative bookmarking, tagging and multi-agent systems
* Static and dynamic models of Web structure and Web growth
* Analysis of network structures within and beyond individual
  communities on the Web
* Incentive and monetization systems
* Information diffusion on the Web,
* Web and Web application governance,
* Novel visualisation techniques for Web related data
* Integrating computational network analysis and semantic web
  techniques, for example to enhance the mainly structure-based network
  analysis by semantic information
* Case studies of communities such as Wikipedia, Facebook, Twitter,
  World of Warcraft, open source software as well as empirical findings
  in social computing-related applications

In particular, we aim at collecting a set of requirements, architectural 
styles and metaphors for Web science.
It is the target of such terminology and figures to build bridges of 
understanding between the different communities serving the need to 
appropriately //analyse// and //develop// social Web applications.


===Important Dates===
* 07.05.2010 **Paper Submission**
* 24.05.2010 **Acceptance Notification**
* 30.06.2010 **Final paper version due**
* 28.09.2010 **Workshop in conjunction with the GI-Jahrestagung**

Why didn't you publish 140 billion triples, by publishing 10 Billion

Looks like you stopped at 1 Billion:

Semantic Pingback

[Sören Auer]

Hi all,

Sebastian was announcing the Semantic Pingback approach and 
implementations last week, unfortunately with missing subject header. I 
would like to draw your attention again on Semantic Pingback, since I 
consider it a crucial building block for the Linked Data Web:


http://aksw.org/Projects/SemanticPingBack

* it is downward compatible to the conventional blogosphere Pingback
* it helps data publishers to keep their data updated and interlinked
* it gives direct benefit to data publishers (i.e. usage notifications)

Please consider adding Semantic Pingback support to your published 
datasets and semantic web tools.


Best,

Sören

[Ann] LESS - Content Syndication based on Linked Data

[Sören Auer]

Hi all,

On behalf of the AKSW research group [1] and Netresearch GmbH [2] I'm 
very pleased to announce LESS - an end-to-end approach for the 
syndication and use of linked data based on the definition of 
visualization templates for linked data resources and SPARQL query results.


Such syndication templates are edited, published and shared by using 
LESS' collaborative Web platform. Templates for common types of entities 
can then be combined with specific, linked data resources or SPARQL 
query results and integrated into a wide range of applications, such as 
personal homepages, blogs/wikis, mobile widgets etc.


LESS and further information and documentation can be found at:

http://less.aksw.org

Particular thanks go to Raphael Doering (Netresearch) who performed most 
of the development work and to Sebastian Dietzold (AKSW) for 
contributing in various ways.


Cheers,

[cfp] 5th Open Knowledge Conference (OKCon 2010)

[Sören Auer]

OKCon, now in its fifth year, is the interdisciplinary conference that 
brings together individuals from across the open knowledge spectrum for 
a day of presentations and workshops.


Open knowledge (http://opendefinition.org) promises significant social 
and economic benefits in a wide range of areas from governance to 
science, culture to technology. Opening up access to content and data 
can radically increase access and reuse, improving transparency, 
fostering innovation and increasing societal welfare.


In addition to high profile initiatives such as Wikipedia, OpenStreetMap 
and the Human Genome Project, there is enormous growth among open 
knowledge projects and communities at all levels. Moreover, in the last 
year, many governments across the world have begun opening up their data.


And it doesn't stop there. In academia, open access to both publications 
and data has been gathering momentum, and similar calls to open up 
learning materials have been heard in education. Furthermore, this 
gathering flood of open data and content is the creator and driver of 
massive technological change. How can we make this data available, how 
can we connect it together, how can we use it collaborate and share our 
work?

relational databases as RDF and Linked Data.


This release includes in particular:

* a *metadata extension* created by Olaf Hartig for generating and
  representing provenance information

* support for *Extract-Tranform-Load (ETL) cycles*, since Triplify can
  be called directly from the command line.

* extension of the default behavior for mapping URIs to SQL queries by
  using *regular expressions to match request URL’s*.

More information can be also found on the documentation page:

http://triplify.org/Documentation

Special thanks go to Sebastian Dietzold and Soren Roug.

The complete OSM dataset amounting roughly 3B triples is now available from:

http://linkedgeodata.org/Datasets

As already noted earlier, however, for most use cases the LGD Elements 
dataset might be the more interesting and manageable one.

[Ann] LinkedGeoData.org

[Sören Auer]

Dear Colleagues,

On behalf of the AKSW research group [1] I'm pleased to announce the 
first public version of the LinkedGeoData.org datasets and services.


LinkedGeoData is a comprehensive dataset derived from the OpenStreetMap 
database covering RDF descriptions of more than 350 million spatial 
features (i.e. nodes, ways, relations).


LinkedGeoData currently comprises RDF dumps, Linked Data and REST 
interfaces, links to DBpedia as well as a prototypical user interface 
for linked-geo-data browsing and authoring.


More information can be found at: http://linkedgeodata.org

Best,

Sören Auer

That might take another week or so, but for most use cases the elements 
data set should be sufficient, since it contains the most interesting 
information.
I guess the complete dataset will be a real challenge for most triple 
stores - not that they won't be able to store the data, but efficient 
querying will be very challenging and I even have some doubts that it is 
reasonable to use this data with a triple store at all. But we will try 
to make it available anyway ;-)


  Open streetmap are voting soon on whether to adopt the open data
 commons sharealike database license. If they adopt it will you also
 adopt it for this data?

Sure!

Re: Keeping crawlers up-to-date

[Sören Auer]

Hi Yves, all,

We envisioned publishing updates of LOD sources via a special LOD 
resource space on the LOD endpoint.
The basic idea is to publish nested sets of updates as linked data for 
years, months, days, hours, minutes, seconds.
This allows crawlers to only update resources which were recently 
changed. The idea is implemented and described for Triplify at:


http://triplify.org/vocabulary/update

There is also a section on that in the paper:

Triplify - Lightweight Linked Data Publication from Relational 
Databases. Proceedings of WWW 2009.

Re: [Ann] OSM Linked Geo Data extraction, browser editor

[Sören Auer]

Bernard Vatant wrote:

Have you any plans to link those data with geonames.org data?


Yes and no ;-)
Of course we want to interlink the OSM data with as many other data 
sources as possible. Candidates are Geonames, Wiki/DBpedia, 
Worldfactbook, OpenResearch [1] etc.
Such interlinkages fit also very well into the OSM data model (which is 
very close to RDF in many aspects). Basically everybody can start 
creating links between the data sources by either using 
http://LinkedGeoData.org/browser or via OSM's REST API (any other OSM 
editor will do as well). Right now we are busy creating an complete RDF 
dump and setting up the bi-directional live syncronization between 
LinkedGeoData.org and OSM. So feel free to create mappings and store 
them in OSM's DB via its API. They will then also show up automatically 
on LinkedGeoData.org.


Best,

Sören

[Ann] OSM Linked Geo Data extraction, browser editor

[Sören Auer]

Hi all,

We were working in the last weeks on bringing geo data derived from the 
marvelous OpenStreetMap project [1] to the data web. This work in 
progress is still far from being finished, however, we would like to 
share some first preliminary results:


* A *vast amount of point-of-interest descriptions* was extracted from 
OSM and published as Linked Data at http://linkedgeodata.org


* The *Linked Geo Data browser and editor* (available at 
http://linkedgeodata.org/browser) is a facet-based browser for geo 
content, which uses an OLAP inspired hypercube for quickly retrieving 
aggregated information about any user selected area on earth.


Further information can be also found in our AKSW project description:

http://aksw.org/Projects/LinkedGeoData

Thanks go to Sebastian Dietzold, Jens Lehmann, Sebastian Hellmann, David 
Aumueller and other members of the AKSW team for their contributions.


Merry Christmas to everybody from Leipzig

Sören

Nice work, you beat me to it. :-)
But since you take a slightly different approach, I think I'll publish 
my OSM Wrapper anyway.



Sure, the more the merrier ;-)
Maybe we can have some more discussions about the conceptual differences 
and similarities and ultimately maybe even join efforts?

Re: Pushing back into Wikipedia? Re: ANN: DBpedia 3.2 release, including DBpedia Ontology and RDF links to Freebase

[Sören Auer]

Tim Berners-Lee wrote:
 Now that there has been so much clean-up work which has been done, has
 there been any discussion of pushing back the cleanliness into the
 wikipedia pages themselves, so that the wikipedia gains in consistency?

Yes, we are thinking about this quite a while. The first step will be to 
set up some kind of live-syncronization between Wikipedia and DBpedia. 
For this we already got access to the live-stream of Wikipedia updates 
from Wikimedia's Brion Vibber. As a second step the DBpedia additions 
will be integrated back as annotations into Wikipedia pages. As a result 
there would be some kind of roundtrip-engineering between bot possible: 
If people see a error or mistake they can correct in Wikipedia and the 
correction will show up on DBpedia. However, we have to be careful not 
to overstrain Wikipedians, since they are usually more interested in 
texts than structure ;-)

Re: Linked Movie DataBase

[Sören Auer]

Hi Oktie, all,

Great work you have done with LinkedMDB.org!

I would like to point you to another open movie data related project: 
Open Movie Database (http:/omdb.org), which contains very high quality 
data and is completely free and open.


As a small exercise and to test Triplify with a larger dataset I created 
a triplification for OMDB, which is accessible at:


http://triplify.org/omdb/triplify/

The used Triplify configuration is available at [1].

Best,

Sören

[Ann] Triplify 0.4

[Sören Auer]

Hi all,

we just release version 0.4 of the Triplify script. After the initial
release several months ago we made quite some additions and bug fixes
the most important of which are:

 * *update log functionality* added - allows Semantic Web crawlers to
   get incremental updates, see
  http://triplify.org/vocabulary/update
 * linked data publication now also works without Apache's mod_rewrite
 * Syntax for indicating objectProperties added, e.g.:
 SELECT id,user_id 'sioc:has_creator-user'
 * Additional metadata can now be added via $triplify['metadata']
 * The configuration variable $triplify['CallbackFunctions'] allows
   programmatic post processing of DB content

Thanks to everybody contributing bug fixes or comments (especially
Sebastian Hellmann, Danh Le Phuoc, Rolf Strathewerd, Elias Theodorou).

3 more weeks: LOD Triplification Challenge

[Sören Auer]

Hi all,

Together with this years I-Semantics conference we are organizing a
Linking Open Data Triplification Challenge. Submission deadline is in 
three weeks (30th of June).


The challenge aims at expediting the process of revealing and exposing
structured (relational) representations, which already back most of the
existing Web sites, as well as raising awareness in the Web Developer
community and showcasing best practices.

The challenge awards attractive prices (MacBook Air, EeePC, iPod) to the
most innovative and promising semantifications. The prizes are kindly
sponsored by OpenLink Software [2], Punkt.NetServices [3] and InfAI [4].

More Information about the challenge can be found at:

http://triplify.org/Challenge

I think outreach to the Web developer communities (as intended with the
challenge) is really crucial right now to expedite the Semantic Web
deployment and I would be very excited if you support this effort - e.g.
by spreading the word and/or submitting to the challenge.

Best,

Sören
