W3C is organizing a Workshop on the Next Steps for RDF around June,2010 as described in the Call for Participation. The deadline forposition papers is 29-March-2010. Each participant in the workshop mustbe associated with a position paper. W3C membership is not requiredto participate in the Workshop.
The goal of the workshop is to gather feedback from the Web communityon whether and, if yes, in which direction RDF should evolve. One ofthe main issues the Workshop should help deciding is whether it istimely for W3C to start a new RDF Working Group to define and standardizea next version of RDF.
While a new version of RDF may include changes in terms of features,semantics, and serialization syntax(es), backward compatibility is ofa paramount importance. Indeed, RDF has been deployed by tools andapplications, and the last few years have seen a significant uptake ofSemantic Web technologies and publication of billions of triples stemmingfrom public databases (see, eg, the Linked Open Data community). Itwould be, therefore, detrimental to this evolution if RDF was seen asunstable and if the validity of current application would be jeopardizedby a future evolution. As a consequence, with any changes of RDF,backward compatibility requirements should be formalized..."
