The BBC has provided a W3C Semantic Web Use Case on how Semantic Web Technologies are used on some of the BBCâ€™s Web Sites. The main characteristics of the BBCâ€™s approach is to use the Web as a Content Management System. Sites like the BBC Music, BBC Programmes, or the BBC Wildlife Finder rely on external, publicly available datasets like Musicbrainz or Wikipedia; the BBC sites themselves show an aggregated view of this information, put in a BBC context. Furthermore, the BBC also creates Web identifiers for every item it has interest in; RDF representations of these Web identifiers allow developers to use the BBCâ€™s data to build applications.
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.
