#semanticweb and #linkeddata have been very busy and #semtech peaked with more than one tweet per minute during the Semantic Technology Conference 2011 in San Fransisco 5-9 June.
For me, here over in Sweden, it's been a couple of late evenings and some busy mornings catching up on Twitter while commuting. Below some of the presentations, discussions, and blogs I did find extra interesting.
A couple of days before the conference the news came out on Twitter about the announcement from Google, Yahoo and Microsoft (Bing) on their joint schema.org. A global, single vocabulary and the use of Microdata to encode structured data into web-pages using this vocabulary for search engines to do a better job.

with "Thing" in the center of it
The first comment I re-tweeted as a "I Liked" on this topic was a tweet on Friday 5 June by Darin L. Stewart (@darinlstewart) pointing to his posting on Gartner's blog: Schema.org: Webmaster One-Stop or Linked Data Land Grab? With some early critique. At the same time came the first version of a RDF Schema version of the vocabulary on schema.rdfs.org. Great job done by Michael Hausenblas (@MHausenblas) et al.. And I did find it interesting to read the quick, positive comment from Chris Bizer, the Linked Data guru behind DBpedia, on Google's official webmaster blog. During the conference schema.org was also the *hot* topic and late Wednesday evening my time I followed a heated online IRC discussion from the BOF on structured data in HTML and vocabularies.

Linked Data Tutorial and Cookbook
Among all the tutorials and presentations at the conference I picked up two great Linked Data resources, First of all Juan Sequeda's (@juansequeda) tutorial series, and also a presentation "I liked, very much"- T
Clinical quality linked data on health.data.gov, presented by George Thomas (@georgethomas). See also his blog post on data.gov with an excellent argumentation for linking publicly available health data such as hospital compare data:
In addition to making flatfiles available to download on the Web, and providing applications that enable programmatic access to backend databases through the Web, imagine using the Web itself as a database: a massively distributed, decentralized database. This is what Linked Data is about – putting data in the Web.
Two technologies to catch up with
Many tweets talked two Calimachus, a framework for data-driven applications based on Linked Data principles allowing Web authors to quickly and easily create semantically-enabled Web applications. I will have a look at the Calimaschus videos they published. And a presentation on Semantic Architecture & Composing Resource Oriented System, by Brian Sletten (@bsletten), made me curios to learn more about the architecture thinking called NetKernel.
Other blog posts
I look forward to read several reflective blog posts the coming week when the participants are back home. For example, I look forward to see what Darin L. Stewart (@darinlstewart) will report from SemTech 2011 on his Gartner blog. I will update this blog post with links to what I find interesting.
