The W3C Semantic Web Best Practices and Deployment Working Group has posted updated working drafts on SKOS, the Simple Knowledge Organisation System. "SKOS Core provides a model for expressing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading lists, taxonomies, 'folksonomies', other types of controlled vocabulary, and also concept schemes embedded in glossaries and terminologies. The SKOS Core Vocabulary is an application of the Resource Description Framework (RDF), that can be used to express a concept scheme as an RDF graph. Using RDF allows data to be linked to and/or merged with other data, enabling data sources to be distributed across the web, but still be meaningfully composed and integrated." The SKOS Core Guide "is a guide using the SKOS Core Vocabulary, for readers who already have a basic understanding of RDF concepts." The SKOS Core Vocabulary Specification "gives a reference-style overview of the SKOS Core Vocabulary as it stands at the time of publication. It also describes the policies for ownership, naming, persistence and change by which the SKOS Core Vocabulary is managed."

The W3C Web Services Description Working Group, has posted the first public working draft of Web Services Description Language (WSDL) Version 2.0: RDF Mapping. "Web Services Description Language (WSDL) provides a model and an XML format for describing Web services. This document describes a representation of that model in the Resource Description Language (RDF) and in the Web Ontology Language (OWL), and a mapping procedure for transforming particular WSDL descriptions into their RDF form."

The W3C RDF Data Access Working Group has published the first working draft of SPARQL Protocol for RDF Using WSDL 1.1. "The RDF Data Access Working Group normatively defines the SPARQL Protocol for RDF via a Web Services Description Language version 2.0 (WSDL 2.0) definition. This document presents a non-normative WSDL 1.1 document defining the same protocol."

The W3C has published the first public working draft of Scope of Mobile Web Best Practices. "To help frame the development of 'best practices' for the mobile Web this document - created by the members of the Mobile Web Initiative Best Practices Working Group ( BPWG) as an elaboration of its charter - identifies the nature of problems to be solved, outlines the scope of work to be undertaken and specifies the assumptions regarding the target audience and the anticipated deliverables."
