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:

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 :)
As Mark pointed it out on his blog: RDFa is about to lift-off! Quick links:
Take a look at it and start playing around ;)
Congrats to Dan Connolly and the GRDDL WG. Today the Semantic Web Activity News announced the GRDDL Recommendation status; see also:
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.
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 Though I read the manual (which seems a bit outdated), I did not figure out how to find certain instances.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 ;)
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.
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 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.
Just came accross Disco - Hyperdata Browser.
Looks nice ;)
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.
Frankly, I am not superstitious, but I do believe seber when he predicts for 2007:
"Semantic Web products will come of age in 2007 [...] the Semantic web is coming - particularly with the work of companies like RadarNetworks and Metaweb.
We think companies like that will come up with the plumbing to help generate RDF based on HTML."
