OWL 2, part of W3C's Semantic Web toolkit, allows people to capture their knowledge about a particular domain (say, energy or medicine) and then use tools to manage information, search through it, and learn more from it. As an open standard based on Web technology, OWL 2 lowers the cost of merging knowledge from multiple domains. More than a dozen implementations of OWL 2 are already available. The standard consists of 13 documents, of which 4 are instructional. Today W3C announces a new version of a standard for representing knowledge on the Web.

It is hoped that they will inspire further contributions to the ongoing work of the Health Care and Life Sciences Interest Group and its Scientific Discourse Task Force, as well as inspire those in other domains to exploit the Semantic Web. The W3C Semantic Web in Health Care and Life Sciences Interest Group (HCLS) is pleased to announce the publishing of three Interest Group notes by the Scientific Discourse Task Force:

]]> First drafts for SPARQL 1.1 published http://www.w3.org/blog/SW/2009/10/23/first_drafts_for_sparql_1_1_published 2009-10-23T08:06:46Z Ivan Herman Activity news The W3C SPARQL Working Group published the First Public Working Draft of six SPARQL 1.1 specifications. SPARQL is the query language of the Semantic Web, and SPARQL 1.1 enhances the SPARQL landscape with: 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 - 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.
