Briefly, there are 8 things I think should be defined, including instance URIs and vocabulary terms to be used for the service description: 1) URIs for the SPARQL 2.0 language and its subsets (query, update, safe, ...) 2) A class for SPARQL endpoints 3) URIs for built-in functions (both filter/project and aggregate functions) that lack existing URIs 4) URIs for supported entailment regimes 5) A property relating an endpoint to its supported entailment regime(s) 6) A property for supported extension functions 7) A property for supported extensions to SPARQL itself 8) A property for relating an endpoint to a description of its dataset (leaving the details to VoiD or other vocabularies) There's a bit more detail on the wiki page, along with a few other things that were either mentioned in previous DAWG work or appear in existing vocabularies (SADDLE), but aren't as important or relevant, imo. thanks, greg [1] http://www.w3.org/2009/sparql/wiki/Feature:ServiceDescriptions#Strawman_Proposal_for_Service_Description_Vocabulary_and_URIs
