The W3C RDF Data Access Working Group has posted a new candidate recommendation of SPARQL Query Language for RDF:

RDF is a directed, labeled graph data format for representing information in the Web. This specification defines the syntax and semantics of the SPARQL query language for RDF. SPARQL can be used to express queries across diverse data sources, whether the data is stored natively as RDF or viewed as RDF via middleware. SPARQL contains capabilities for querying required and optional graph patterns along with their conjunctions and disjunctions. SPARQL also supports extensible value testing and constraining queries by source RDF graph. The results of SPARQL queries can be results sets or RDF graphs.

Two features are identified as being "at risk", REDUCED and leading digits in prefixed names. I have no idea how significant these are. The latter at least strikes me as a really bad idea. Comments are due by August 31.
