SPARQL 1.1 Specifications are W3C Recommendations

The SPARQL Working Group has completed development of its full-featured
system for querying and managing data using the flexible RDF data model. It
has now published eleven Recommendations for SPARQL 1.1, detailed in SPARQL
1.1 Overview. SPARQL 1.1 extends the 2008 Recommendation for SPARQL 1.0 by
adding features to the query language such as aggregates, subqueries,
negation, property paths, and an expanded set of functions and operators.
Beyond the query language, SPARQL 1.1 adds other features that were widely
requested, including update, service description, a JSON results format,
and support for entailment reasoning.
