WebSimpleDB API First Draft Published

2009-09-29: The Web Applications Working Group has published the First Public Working Draft of WebSimpleDB API. User agents need to store large numbers of objects locally in order to satisfy off-line data requirements of Web applications. Whereas the Web Storage specification is useful for storing pairs of keys and their corresponding values, it does not provide in-order retrieval of keys, efficient searching over values, or storage of duplicate values for a key. The new WebSimpleDB API specification provides a concrete API to perform advanced key-value data management that is at the heart of most sophisticated query processors. It does so by using transactional databases to store keys and their corresponding values. Learn more about the Rich Web Client Activity. (Permalink)

W3C Invites Implementations of Timed Text (TT) Authoring Format 1.0 - Distribution Format Exchange Profile (DFXP)

2009-09-24: The Timed Text Working Group invites implementation of the Candidate Recommendation of Timed Text (TT) Authoring Format 1.0 - Distribution Format Exchange Profile (DFXP), used to represent timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information. The specification provides a standardized representation of a particular subset of textual information with which stylistic, layout, and timing semantics are associated by an author or an authoring system for the purpose of interchange and potential presentation.

Last Call: Mathematical Markup Language (MathML) Version 3.0

2009-09-24: The Math Working Group has published a Last Call Working Draft of Mathematical Markup Language (MathML) Version 3.0. MathML is an XML application for describing mathematical notation and capturing both its structure and content. The goal of MathML is to enable mathematics to be served, received, and processed on the World Wide Web, just as HTML has enabled this functionality for text. Comments are welcome through 11 November. Learn more about the Math Activity. (Permalink)

Five Web Services Drafts Updated

2009-09-24: The Web Services Resource Access Working Group published updates to five Working Drafts: Web Services Enumeration (WS-Enumeration), Web Services Eventing (WS-Eventing), Web Services Resource Transfer (WS-RT), Web Services Transfer (WS-Transfer), and Web Services Metadata Exchange (WS-MetadataExchange). The first describes a general SOAP-based protocol for enumerating a sequence of XML elements that is suitable for traversing logs, message queues, or other linear information models. The second describes a protocol that allows Web services to subscribe to or accept subscriptions for event notification. The third defines extensions to WS-Transfer that deal primarily with fragment-based access to resources to satisfy the common requirements of WS-ResourceFramework and WS-Management. The fourth describes a general SOAP-based protocol for accessing XML representations of Web service-based resources. The fifth defines how metadata associated with a Web service endpoint can be represented as resources, how metadata can be embedded in endpoint references, and how metadata could be retrieved from a Web service endpoint.

W3C Organizes Workshop on Access Control Application Scenarios

2009-09-22: W3C invites people to participate in a Workshop on Access Control Application Scenarios on 17-18 November 2009 in Luxembourg. This Workshop is intended to explore evolving application scenarios for access control technologies, such as XACML. Results from a number of recent European research projects in the grid, cloud computing, and privacy areas show overlapping use cases for these technologies that extend beyond classical intra-enterprise applications. The Workshop, co-financed by the European Commission 7th framework program via the PrimeLife project, is free of charge and open to anyone, subject to review of their statement of interest and space availability. Position papers are due 23 October. See the call for participation for more information. Learn more about the Privacy Activity. (Permalink)

OWL 2 is a Proposed Recommendation

2009-09-22: With more than a dozen implementations of OWL 2 reported, the OWL Working Group has published its OWL 2 Web Ontology Language as a Proposed Recommendation. An ontology is a structured set of terms that a particular community uses for organizing data, such as "title", "author", and "ISBN" for data about books. OWL 2 is a compatible extension to OWL 1, providing additional features for people using ontologies. The OWL 2 document set contains 13 documents, of which 4 are instructional: overview , primer, new features and rationale, and quick reference. The rdf:PlainLiteral datatype, developed for use by OWL 2 and RIF, is also a Proposed Recommendation. Learn more about the Semantic Web. (Permalink)

New W3C Group to Standardize Relational Database, RDF Mapping

2009-09-16: W3C announces today the new RDB2RDF Working Group, whose mission is to standardize a language for mapping relational data and relational database schemas into RDF and OWL, tentatively called the RDB2RDF Mapping Language, R2RML. From the beginning of the deployment of the Semantic Web there has been increasing interest in mapping relational data to the Semantic Web. This is to allow relational data to be combined with other data on the Web, to link semantics directly to relational data and to aid in enterprise data integration. The creation of this Working Group follows the work of a previous W3C Incubator Group in this area. Read the RDB2RDF Working Group Charter and learn more about the Semantic Web. (Permalink)

CSS Working Group Updates Candidate Recommendation of CSS3 Media Queries

2009-09-15: The Cascading Style Sheets (CSS) Working Group invites implementation of the Candidate Recommendation of Media Queries. HTML4 and CSS2 currently support media-dependent style sheets tailored for different media types. For example, a document may use sans-serif fonts when displayed on a screen and serif fonts when printed. "screen" and "print" are two media types that have been defined. Media queries extend the functionality of media types by allowing more precise labeling of style sheets. Learn more about the Style Activity. (Permalink)

W3C Invites Implementations of WebCGM 2.1

2009-09-15: The WebCGM Working Group invites implementation of the Candidate Recommendation of WebCGM 2.1. Computer Graphics Metafile (CGM) is an ISO standard, defined by ISO/IEC 8632:1999, for the interchange of 2D vector and mixed vector/raster graphics. WebCGM is a profile of CGM, which adds Web linking and is optimized for Web applications in technical illustration, electronic documentation, geophysical data visualization, and similar fields. The Working Group has adopted a public test suite for WebCGM 2.1 and has produced a preliminary WebCGM 2.1 implementation report. Learn more about the Graphics Activity. (Permalink)
