Developer Gathering during W3C Technical Plenary Week

   As part of its efforts to broaden participation opportunities
   in W3C, W3C announces today its first Developer Gathering, to
   be held 5 November, 2009 during the W3C Technical Plenary Week
   (TPAC) in Santa Clara, California. Registration is open to the
   public; W3C is seeking in particular developers and designers
   who may not participate regularly in W3C groups. Arun
   Ranganathan (Mozilla), Fantasai, Philippe Le Hégaret, and
   others will speak on a variety of hot topics with a goal of
   feeding back comments to the groups developing the relevant
   technology standards. Learn more about the Developer Gathering.


WebSimpleDB API First Draft Published

   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.


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

   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. Learn more about the
   Video in the Web Activity.


Last Call: Mathematical Markup Language (MathML) Version 3.0

   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.


Five Web Services Drafts Updated

   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. Learn more about the
   Web Services Activity.


W3C Organizes Workshop on Access Control Application Scenarios

   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.


W3C Launches Provenance Incubator Group

   W3C is pleased to announce the creation of the Provenance
   Incubator Group, whose mission is to provide a state-of-the art
   understanding and develop a roadmap in the area of provenance
   for Semantic Web technologies, development, and possible
   standardization. The group will be chaired by Yolanda Gil. The
   following W3C Members have sponsored the charter for this
   group: Renssealaer Polytechnic Institute, Talis Information
   Limited, University of Manchester, University of Southampton,
   University of Southern California Information Sciences
   Institute (USC / ISI), and Vrije Universiteit. Read more about
   the Incubator Activity, an initiative to foster development of
   emerging Web-related technologies. Incubator Activity work is
   not on the W3C standards track.


OWL 2 is a Proposed Recommendation

   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.


New W3C Group to Standardize Relational Database, RDF Mapping

   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.


CSS Working Group Updates Candidate Recommendation of CSS3 Media

   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.


W3C Invites Implementations of WebCGM 2.1

   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.


Protocol for Web Description Resources (POWDER): Test Suite Note

   The Protocol for Web Description Resources (POWDER) Working
   Group has published a Group Note of "Protocol for Web
   Description Resources (POWDER): Test Suite." This document
   presents test cases for the POWDER technology, which helps to
   build a Web of trust and make it possible to discover relevant,
   quality content more efficiently. The tests facilitate and
   exemplify the creation of POWDER documents of varying
   complexity and provide a means to assert the conformance of
   software applications designed to handle POWDER documents.
   Learn more about the Semantic Web.


Web Storage; Web Database Drafts Published

   The Web Applications Working Group has published Working Drafts
   of "Web Storage" and "Web Database" (a First Public Draft). The
   former defines an API for persistent data storage of key-value
   pair data in Web clients. The latter defines an API for storing
   data in databases that can be queried using a variant of SQL.
   Learn more about the Rich Web Client Activity.


New eGovernment Activity Focus Proposed; Guidelines for Publishing
Open Government Data Published

   Today, the World Wide Web Consortium (W3C) announces a draft
   work plan for the eGovernment Interest Group, whose mission is
   to document, advocate, coordinate and communicate best
   practices, solutions and approaches to improve the interface
   between citizens and government through effective use of Web
   standards. The draft charter, in review by the W3C community
   until the end of September, focuses on two topics: Open
   Government Data (OGD), and Education and Outreach. In line with
   its anticipated focus on Open Government Data, the group also
   announces today a first draft of "Publishing Open Government
   Data," which provides step-by-step guidelines for putting
   government data on the Web. Sharing data according to these
   guidelines enables greater transparency; delivers more
   efficient public services; and encourages greater public and
   commercial use and re-use of government information. Learn more
   about the W3C eGovernment Activity.


Authoring HTML: Handling Right-to-left Scripts Group Note Published

   The Internationalization Core Working Group has published
   "Authoring HTML: Handling Right-to-left Scripts" as a Working
   Group Note. This document describes techniques for the use of
   HTML markup and CSS style sheets when creating content in
   languages that use right-to-left scripts, such as Arabic,
   Hebrew, Persian, Thaana, Urdu, etc. It builds on (but also goes
   beyond) markup needed to supplement the Unicode bidirectional
   algorithm, and also touches on how to prepare content that will
   later be localized into right-to-left scripts. Learn more about
   the Internationalization Activity.


New Draft of DOM Level 3 Events Published

   The WebApps Working Group has published a new Working Draft of
   "DOM Level 3 Events," a generic platform- and language-neutral
   event system which allows registration of event handlers,
   describes event flow through a tree structure, and provides
   basic contextual information for each event. DOM3 Events
   introduces an advanced text and keyboard event model, including
   composition events for input-method editors and other
   internationalization issues. Learn more about the Rich Web
   Client Activity


Cascading Style Sheets Level 2 Revision 1 (CSS 2.1) Candidate
Recommendation Updated

   The Cascading Style Sheets (CSS) Working Group has updated the
   Candidate Recommendation of "Cascading Style Sheets Level 2
   Revision 1 (CSS 2.1) Specification." This specification
   defines Cascading Style Sheets, level 2 revision. CSS 2.1 is a
   style sheet language that allows authors and users to attach
   style (e.g., fonts and spacing) to structured documents (e.g.,
   HTML documents and XML applications). This update corrects some
   errata in the previous draft. Learn more about the Style


W3C Opens New India Office
