Semantic Web Activity News
The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries. It is a collaborative effort led by W3C with participation from a large number of researchers and industrial partners. It is based on the Resource Description Framework (RDF).

Last Call for Six Rule Interchange Format (RIF) Drafts
The W3C Rule Interchange Format (RIF) Working Group has published six Last Call Working Drafts. Together, they allow systems using a variety of rule languages and rule-based technologies to interoperate with each other and with other Semantic Web technologies. Three of the drafts define XML formats with formal semantics for storing and transmitting rules:
- The RIF Production Rule Dialect (PRD) is designed for the kinds of rules used in modern Business Rule Management systems.
- The RIF Basic Logic Dialect (BLD) is a foundation for Logic Programming, classical logic, and related formalisms.
- The RIF Core Dialect is the common subset of PRD and BLD, useful when having a ubiquitous platform is paramount.
- RIF Datatypes and Builtins (DTB) specifies the datatypes and standard operations (modeled on XPath Functions) available in all RIF dialects
- RIF RDF and OWL Compatibility specifies how RIF works with RDF, RDFS, OWL 1, and OWL 2.
- RIF Framework for Logic Dialects (FLD) provides a mechanism for specifying extended dialects, beyond BLD, when more expressive power is required.

XSPARQL published as a W3C Submission
The “XSPARQL” specification has been published as a W3C member submission, co-authored by experts of Asemantics S.R.L., DERI Galway, Fundación CTIC, INRIA, Ontotext, OpenLink Software Inc., Profium, Talis Information Ltd., and the University of Innsbruck. This specification defines a merge of SPARQL and XQuery, and has the potential to bring XML and RDF closer together. XSPARQL provides concise and intuitive solutions for mapping between XML and RDF in either direction, addressing both the use cases of GRDDL and SAWSDL.

Last Call: Delivery Context Ontology
The W3C Ubiquitous Web Applications Working Group has published a Last Call Working Draft of Delivery Context Ontology. A "Delivery Context" is a source of information that can help create context-aware applications, thus providing a compelling user experience. The Delivery Context Ontology specification provides a formal model of the characteristics of the environment in which devices interact with the Web or other services. The Delivery Context includes the characteristics of the Device, the software used to access the service and the Network providing the connection among others. Comments are welcome through 07 July.

First Draft Published for Ontology for Media Resource
The W3C Media Annotations Working Group has published the First Public Working Draft of Ontology for Media Resource 1.0. This specification defines an ontology for cross-community data integration of information related to media resources, with a particular focus on media resources on the Web. The ontology is supposed to foster interoperability and counter the current proliferation of video metadata formats by providing full or partial translation and mapping towards existing formats.
