venue * participants * agenda (Thu, Fri) * records (actions, decisions, irc logs)

The RDF Core and Web Ontology Working Group issues lists contain a number of issues postponed (RDF Core postponed issues, WebOnt issues ) for future work. Some of these seem to have impact beyond the scope of those specifications alone, impact on Semantic Web Architecture. These issues a reflect @@ expand on issues of best practice, deployment, future directions @@. The Semantic Web Coordination Group is organizing a meeting to explore these issues.

Venue

Royal Sonesta Hotel, Cambridge, MA, USA. Skyline B, per schedule as of 10 Feb, subject to change.

Registration closed 26 February 2003). A list of registered attendees is maintained by the tech plenay organizers, though it suffers from various artifacts because this meeting replaced an RDF Core WG meeting in the registration system.

Aside: Fun with Relational Databases on the Semantic Web

Using dbview.py, an implementation of Relational Databases on the Semantic Web, we exported the registration data for this meeting, tpreg.rdf from the mySQL database behind the meeting registration system; then a simple XSLT transformation, whoFmt.xsl maps it to HTML for display. We store the HTML results, tpreg-out.html, for clients that are not yet XSLT-capable.
