The last week of June, participants at the W3C RDF Next Steps Workshop concluded that support for JSON, Turtle, and for "Named Graphs" are top priorities for any future work on RDF. Participants also highlighted the importance of compatibility with existing deployment. Read about these and other topics in the Workshop report. To join the discussion about organizing future work on RDF, please share your thoughts on the Semantic Web Interest Group mailing list (with a copy to the separate RDF Comments list). W3C thanks the National Center for Biomedical Ontology at Stanford, Palo Alto, USA, for hosting the Workshop. Learn more about the Semantic Web.
