RDFa is Candidate Recommendation

mhausenblas — Sat, 21 Jun 2008 18:26:09 +0200

So, yesterday it became reality ;) XHTML+RDFa is finally a W3C Candidate Recommendation (CR) - more details available from the W3C news page.

In case you have an RDFa implementation ready, please let us know.

RDFa Wiki available

http://rdfa.info/wiki/RDFa_Wiki is online - check it out! Many thanks to Ben and CC ;)

The Semantic Web Command Line

mhausenblas — Wed, 20 Feb 2008 22:28:14 +0100

Ever have wondered if there is something around like a command line for the Semantic Web? An online tool that allows you load and query a range of data sources? Well, peradventure Benjamin Nowack has developed a tool, called SPARQLBot, that does all this. It is really great. You launch your favourite IRC client (I use Hydra IRC) and then you (or a SPARQL geek near to you) defines a command that does something useful. Pull in some data, query it, smush it, etc.

Check it out! Play around with it. Experience how to instant-integrate data source on an RDF-basis. You will enjoy it. An example may better illustrate it: Imagine you've joined the #sparqlbot channel at irc:irc.freenode.net; you query for news (from an RSS channel):

mhausenblas>sparqlbot, load <FEEDURI>
mhausenblas>sparqlbot, news about XXX

What happens in the background is that the feed gets loaded into the store, and the command triggers a SPARQL query:

SELECT DISTINCT ?item ?o WHERE {
?item a rss:item ; ?p ?o .
FILTER REGEX(?o, "$1", "i")
}

Isn't that great? I experienced it today. It really rocks :) You can add your own commands (given some basic SPARQL knowledge) and extend the bot's intelligence. Not to mention that this nice tool (being based on ARC2) even understands RDFa - very nice, indeed (try also the 'sw faq command'). However, the name SPARQLBot is to modest, IMHO. It is THE Semantic Web command line!

riese launched!

mhausenblas — Thu, 31 Jan 2008 20:19:39 +0100

So finally we did it: Today we released the alpha version of riese, the 'RDFizing and Interlinking the EuroStat Data Set Effort'. Deploying linked-data using XHTML+RDFa is quite a new idea. We combined it with what we call User Contributed Interlinking, i.e. let user add semantic links in a Wiki-style manner. Check it out!

Btw, thanks Danny for your nice post on riese :)

A great RDFa video tutorial ...

... by Manu Sporny (CEO Digital Bazaar, Inc.), available at YouTube: RDFa Basics. Thanks a lot!

Cool RDFa Tutorial

Fabien, you're simply the best: Your RDFa tutorial rocks!

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 ;)

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.

RDFa-deployed Multimedia Metadata (ramm....

mhausenblas — Sat, 28 Jul 2007 08:43:33 +0200

The RDFa-deployed Multimedia Metadata (ramm.x) activity has been launched:

With ramm.x we aim at enabling existing multimedia metadata formats to enter the Semantic Web [...] ramm.x targets at self-descriptive media asset descriptions allowing to apply the follow-your-nose principle.

RDFa applications

mhausenblas — Mon, 05 Mar 2007 09:39:30 +0100

Two new RDFa applications are available:

Ben has announced a new Bookmarklets and RDFa Web Clipboard;
I've put an alpha version of a FOAF-RDFa generator, called FOAFr, online.

Check it out ;)

RDFa news

mhausenblas — Fri, 23 Feb 2007 09:51:20 +0100

Mark Birbek explains how to use RDFa in XHTML 1 - STOP - The RDFa specification (incl. Primer, Syntax, Use Cases, and Test Suite) is on its way - STOP - Bob DuCharme has a nice article that introduces RDFa step by step - STOP - Benjamin Nowack wrote a form-based, semi-automatic comparison matrix for RDFa, eRDF and microformats.

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.

Another good news: Generating RDFa from...

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

RDF in HTML and Microformats

mhausenblas — Tue, 09 Jan 2007 20:57:06 +0100

When Seth states that "[...] Microformats have succeeded here, allowing me to very easily embed metadata into XHTML.", I'd like to reply: You can virtually embed RDF into (X)HTML using RDFa; just as easy as that + you get: multiple Vocs in one place via namespaces, one-tool-for-all-formats, etc.

Want to try out? Go have a look at RDFa bookmarklets.

RDFa Use Cases

mhausenblas — Thu, 21 Dec 2006 20:40:56 +0100

In the W3C RDF-in-HTML task force, we now establish use cases for RDFa.
