Linked Data on the Web Workshop @ WWW08

mhausenblas — Fri, 23 Nov 2007 22:14:27 +0100

The goal of the LDOW08 workshop (at WWW08, April 22, 2008
Beijing, China) is to provide a forum for the Linked Data community, in which participants can:

present and discuss approaches to publishing Linked Data on the Web;
showcase innovative applications that consume Linked Data;
shape the agenda and identify upcoming research issues for the next development stage of the Web of Data.

Deadline: 2008-01-28

SPARQL out!

mhausenblas — Fri, 16 Nov 2007 11:44:39 +0100

SPARQL, the query language for the Semantic Web is a W3C Proposed Recommendation, finally.

Kudos to Eric, Kendall, Lee, Elias and everybody who made it possible :)

Microsoft, RDF & OWL

mhausenblas — Mon, 24 Sep 2007 21:25:11 +0200

Thanks to Danny I learned today that Microsoft and RDF have (from now on) more than the literal 'r' in common: In their Interactive Media Manager MS starts to utilise RDF and OWL ... I really gotta figure out what for ;)

RDFa news

mhausenblas — Mon, 24 Sep 2007 11:41:21 +0200

As Mark pointed it out on his blog: RDFa is about to lift-off! Quick links:

The RDFa Primer, and
The RDFa Syntax

Take a look at it and start playing around ;)

GRDDL is a Recommendation!

mhausenblas — Tue, 11 Sep 2007 21:43:19 +0200

Congrats to Dan Connolly and the GRDDL WG. Today the Semantic Web Activity News announced the GRDDL Recommendation status; see also:

GRDDL TR (http://www.w3.org/TR/2007/REC-grddl-20070911/)
GRDDL Test Cases (http://www.w3.org/TR/2007/REC-grddl-tests-20070911/)

An RDFa browser

mhausenblas — Sun, 02 Sep 2007 20:35:13 +0200

Did you know that the Zitgist RDF browser actually supports RDFa? This is to say you can feed the browser with XHTML+RDFa (see example) and it will render it!

Ok. It has some minor hiccups (seems to duplicate each prop) ... but hey ... it's a start.

Swoogle, Swoogle

mhausenblas — Fri, 20 Jul 2007 12:00:12 +0200

Tim Finin recently announced a new version of Swoogle, THE Semantic Web search engine. After some initial hiccups the service now seems to work fine, again. Thanks to the UMBC eBiquity team, you're doing a great job!

One thing puzzles me. Though I read the manual (which seems a bit outdated), I did not figure out how to find certain instances. Take for example the query 'return all documents that have a foaf:mbox = abc@example.org in it'. I'll continue the experiments ;)

A somewhat other Semantic Web introducti...

mhausenblas — Fri, 01 Jun 2007 17:59:10 +0200

The most enjoyable and understandable introduction to the Semantic Web I came across for ages was given by Stefano Mazzocchi at the ApacheCON 2007:

A no-nonsense introduction to "semantic web" technologies

The so-called "Semantic Web" is a vision for an evolution of the web where web sites expose data not only for direct human consumption (as it is mostly the case today) but also for specific software agents to consume, aggregate and enrich on behalf of humans. In this presentation, I will show an outline of this vision, together with a simple and concise description of each W3C recommendation (such as RDF, OWL and SPARQL) that are involved and how they are supposed to work together. I will also show the differences and similarities between this and other models for purer-data interchange on the web (such as "web 2.0" and "atom/rss") and will demo existing solution that are based on semantic web technologies.

New RDF-izer service by Dave Beckett: Tr...

mhausenblas — Mon, 26 Mar 2007 09:42:32 +0200

Dave Beckett has announced a new cool online service to RDF-ize Web data: Triplr. Check it out!

Good news on SPARQL ...

mhausenblas — Fri, 09 Mar 2007 20:28:48 +0100

As recently announced in Andy Seaborne's blog, SPARQL is now also capable of manipulating RDF graphs:

SPARQL/Update is a language that takes the SPARQL style, and much of the grammar, and provides both graph update and graph management operations.

Kudos to Andy and Geetha!

W3C: Questionnaire on JavaScript-RDF API...

mhausenblas — Tue, 13 Feb 2007 21:17:44 +0100

W3C prepares for Scripting for the Semantic Web:

The W3C Semantic Web Activity is considering whether to propose further work specifying a standard Applications Programming Interface (API) for people writing Semantic Web applications in Javascript running in browsers. Before engaging, possibly, in drafting a charter to be then submitted to W3C members, W3C would like to solicit input from the developers' community. An interactive questionnaire was therefore set up at:
http://www.w3.org/2002/09/wbs/1/semweb-js-api/
to collect community input. W3C would appreciate if interested developers filled the questionnaire to promote consensus on this issue.

BTW: The 3rd Workshop on Scripting for the Semantic Web is colocated with ESWC 2007. June 6 or 7, 2007 Innsbruck, Austria.

Jena now has got GRDDL support

mhausenblas — Fri, 02 Feb 2007 16:06:30 +0100

Want to use legacy HTML on the Web or don't care about migrating to RDF? Use GRDDL! And the best is: Now, Jena can assist you in writing software that does all the GRDDL stuff for you:

Enjoy reading Bob DuCharme's blog post on how to generate RDFa from Movable Type.

Using RDF on the Web: A Survey

Lee Feigenbaum made an excellent survey on using RDF on the Web available.

A Simple Semantic Web Browser

Just came accross Disco - Hyperdata Browser.

Looks nice ;)
