Thursday, April 24th, 2008

Digg starts using RDFa

Friday, April 4th, 2008

Topbraid Composer Supports RDFa

Thursday, March 13th, 2008

TopBraid Composer is a modeling environment for developing Semantic Web ontologies and building semantic applications, built as a plug-in for Eclipse. In part of the description for the product, it says:

“RDFa and GRDDL are evolving W3C standards to embed semantic markup in XHTML pages. Composer can parse such documents to extract RDFa metadata from HTML pages. The metadata can then be treated like any other RDF source, and users can perform DL reasoning or SPARQL queries on it. Together with the other data integration capabilities and visualization tools Composer can be used to develop mash-up applications. TopBraid is also a comprehensive RDFa Editor.”
