New SPARQL drafts published

The W3C SPARQL Working Group has published a First Public Working Draft of SPARQL 1.1 Property Paths, which
defines a more succinct way to write parts of basic graph patterns and also extend matching of triple pattern to arbitrary length paths. The group also published six updates, namely:

SPARQL 1.1 Query adds support for aggregates, subqueries, projected expressions, and negation to the SPARQL query language.
SPARQL 1.1 Update defines an update language for RDF graphs.
SPARQL 1.1 Protocol for RDF defines an abstract interface and HTTP bindings for a protocol to issue SPARQL Query and SPARQL Update statements against a SPARQL endpoint.
SPARQL 1.1 Service Description defines a vocabulary and discovery mechanism for describing the capabilities of a SPARQL endpoint.
SPARQL 1.1 Uniform HTTP Protocol for Managing RDF Graphs describes the use of the HTTP protocol for managing named RDF graphs on an HTTP server.
SPARQL 1.1 Entailment Regimes defines conditions under which SPARQL queries can be used with entailment regimes such as RDF, RDF Schema, OWL, or RIF.
