I've added a section to the service descriptions page with a proposal  
[1]. 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
