The W3C SPARQL Working Group has published two new working drafts. The first is a working draft of SPARQL 1.1 Overview: “This document is an overview of SPARQL 1.1. It provides an introduction to a set of W3C specifications that facilitate querying and manipulating RDF graph content on the Web or in an RDF store. Comments on this document should be sent to email@example.com, a mailing list with a public archive.” View the working draft here.
The second piece is a last call working draft of SPARQL 1.1 Federated Query. According to the abstract, “RDF is a directed, labeled graph data format for representing information in the Web. 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. This specification defines the syntax and semantics of SPARQL 1.1 Federated Query extension for executing queries distributed over different SPARQL endpoints. The SERVICE keyword extends SPARQL 1.1 to support queries that merge data distributed across the Web.” Read this draft here.
