2008-11-14: The XML Security Working Group has published the First Public Working Draft of XML Signature Best Practices. The XML Signature specification offers powerful and flexible mechanisms to support a variety of use cases. This flexibility has the downside of increasing the number of possible attacks. One countermeasure to the increased number of threats is to follow best practices, including a simplification of the use of XML Signature where possible. This document outlines best practices noted by the XML Security Specifications Maintenance Working Group, the XML Security Working Group, and other ideas cited at the Workshop on Next Steps for XML Security. While most of these best practices are related to improving security and mitigating attacks, yet others are for best practices in the practical use of XML Signature, such as signing XML that doesn't use namespaces.

2008-10-14: Social networking is a complex, rapidly expanding, and in some cases, disruptive sector of the information economy. For example, user-generated content is causing changes in the traditional content/media industry structure. In the future, community features may well become an integral part of all digital experiences — from information/publishing to business and entertainment. Companies providing services for social media and social networking must anticipate barriers to industry growth and stability. W3C believes that now is the time for industry to gather to discuss their experience so far, and what barriers they foresee in the near- and medium-term. W3C therefore invites people to participate in a Workshop on the Future of Social Networking, to analyze risks and opportunities of the social networking industry, and to define plans for the future. The Workshop will be held 15-16 January 2009 in Barcelona (Spain) and is hosted by Universitat Politècnica de Catalunya and ReadyPeople. Anyone may attend, but position papers are required and are due November 20. Instructions for workshop registration/participation will be sent exclusively to authors of submitted position papers.

2008-10-09: The OWL Working Group published seven documents yesterday relating to the OWL 2 Web Ontology Language. OWL 2 extends OWL, a core standard of the Semantic Web, adding new features that users have requested and that software providers are prepared to implement. The documents are:
The first three documents form the technical core of OWL 2, which has both a traditional "direct" semantics (for OWL DL) and a new "RDF-based" semantics (for OWL Full). Documents 4 and 5 specify two different serializations for OWL ontologies, one based on RDF and one using XML more directly. Document 6 defines useful subsets of OWL which may be easier to implement or may better meet certain performance requirements. Finally, document 7 specifies conformance and will later enumerate the OWL 2 test cases. Five other documents are under development; but they are not yet ready for public review.

2008-10-08: W3C updated its XHTML Modularization standard today with support for designing modular languages using XML Schema. The addition of schemas to XHTML Modularization 1.1 is an important step towards the XHTML2 Working Group's goal that XHTML support rich Web content and be extensible, while remaining interoperable. A modularization standard allows language designers to reuse elements defined by multiple parties (including other W3C standards such as SVG and MathML) and combine them into new formats to meet specific application needs. The standard allows people to use schema-enabled, off-the-shelf tools to immediately begin authoring and validating documents written in those new languages. The XHTML2 Working Group, which gained experience using Modularization 1.1 to build some modules and languages, now plans to add schema support to other XHTML standards.

When documents (e.g., HTML) are laid out on visual media (e.g., screen or print) and the contents of some element are too large for a given area, CSS allows the designer to specify whether and how the overflow is displayed. One way, available on certain devices, is the "marquee" effect: the content is animated and moves automatically back and forth. This module defines the properties to control that effect. Comments are welcome through 01 September. Learn more about the Style Activity. (Permalink)
2008-08-01: The Mobile Web Best Practices Working Group has published a Last Call Working Draft of Content Transformation Guidelines 1.0. Content Transformation is the manipulation in various ways, by proxies, of requests made to and content delivered by an origin server with a view to making it more suitable for mobile presentation. The overall objective of this document is to provide a means, as far as is practical, for users to be provided with at least a "functional user experience" when accessing the Web with a mobile device. Comments are welcome through 16 September. Learn more about the Mobile Web Initiative. (Permalink)

2008-08-01: The Rule Interchange Format (RIF) Working Group published six documents yesterday:
"RIF Basic Logic Dialect" (BLD) specifies an XML format for rules at an intermediate expressive power. The language is roughly Horn rules with URIs, datatypes, and builtins. This goes beyond datalog (it has function terms), but does not provide any kind of negation. "RIF RDF and OWL Compatibility" explains and specifies how RIF rulesets are to be used in combination with RDF and OWL. Comments on these documents welcome until 19 September. In addition, RIF Production Rule Dialect (PRD) specifies an XML format for the exchange of production rules. PRD and BLD are expected to be the basis of the two main dialect-branches, with RIF Core being the things in common between the two. RIF Framework for Logic Dialects (FLD) and RIF Datatypes and Builtins (DTB) provide common elements for specific dialects to use. RIF Uses Cases and Requirements (UCR), last published about two years ago, has been simplified and now has examples written in the PRD and BLD presentation syntaxes.

2008-07-29: W3C today announced new standards that will make it easier for people to browse the Web on mobile devices. Mobile Web Best Practices 1.0, published as a W3C Recommendation by the Mobile Web Best Practices Working Group, condenses the experience of many mobile Web stakeholders into practical advice on creating mobile-friendly content. These guidelines will help to improve the experience of people browsing the Web on a wide array of mobile handsets. W3C published a second standard today: XHTML Basic 1.1 Recommendation, the preferred format specification of the Best Practices. With this, there is now a full convergence in mobile markup languages, including those developed by the Open Mobile Alliance (OMA). The Working Group also published today the first draft of a next generation of guidelines, Mobile Web Application Best Practices, aimed at mobile Web applications.

2008-07-28: The Efficient XML Interchange Working Group published two Working Drafts today: Efficient XML Interchange (EXI) Format 1.0 and Efficient XML Interchange Evaluation. The former specifies the Efficient XML Interchange (EXI) format. EXI is a very compact representation for the Extensible Markup Language (XML) Information Set that is intended to simultaneously optimize performance and the utilization of computational resources. The EXI format uses a hybrid approach drawn from the information and formal language theories, plus practical techniques verified by measurements, for entropy encoding XML information. Using a relatively simple algorithm, which is amenable to fast and compact implementation, and a small set of data types, it reliably produces efficient encodings of XML event streams. The latter document, a first public draft, is an evaluation of the Efficient XML Interchange (EXI) Format 1.0 with reference to the Properties identified by the (now closed) XML Binary Characterization (XBC) Working Group, relative to XML, gzipped XML and ASN.1 PER.

2008-07-24: The Web Security Context Working Group has published the Last Call Working Draft of Web Security Context: User Interface Guidelines. This specification deals with the trust decisions that users must make online, and with ways to support them in making safe and informed decisions where possible. In order to achieve that goal, this specification includes recommendations on the presentation of identity information by Web user agents. It also includes recommendations on handling errors in security protocols. The error handling recommendations both minimize the trust decisions left to users, and represent known best practice in inducing users toward safe behavior where they have to make these decisions. Comments are welcome through 15 September. Learn more about the Security Activity. (Permalink)
2008-07-24: The SOAP-JMS Binding Working Group has published the First Public Working Draft of SOAP over Java Message Service 1.0.

2008-06-24: W3C is pleased to announce the creation of the Common Web Language (CWL) Evaluation and Installation Incubator Group, sponsored by W3C Members Institute of Semantic Computing (ISeC), (Japan) National Institute of Advanced Industrial Science and Technology (AIST), Keio University, and JustSystems Corporation. The group's mission is to examine Common Web Language in real Web environments using the pilot model of the CWL platform. CWL is a graphic language of semantic network with hyper node and is used to describe contents and meta-data of web pages in three different type of form such as UNL, CDL and RDF. The CWL platform allows people to input CWL using natural languages and display information written in CWL in natural languages. Using this CWL platform, the CWL will be evaluated from multilingualism, semantic computing and semantic web points of view.

2008-06-20: The Semantic Web Deployment Working Group and XHTML2 Working Group have published a Candidate Recommendation of RDFa in XHTML: Syntax and Processing. Web documents contain significant amounts of structured data, which is largely unavailable to tools and applications. When publishers can express this data more completely, and when tools can read it, a new world of user functionality becomes available, letting users transfer structured data between applications and web sites, and allowing browsing applications to improve the user experience. RDFa is a specification for attributes to be used with languages such as HTML and XHTML to express structured data. See the groups' RDFa implementation report. The Working Groups also updated the companion document RDFa Primer. Learn more about the Semantic Web and the HTML Activity. (Permalink)
2008-06-20: The XML Schema Working Group has published Last Call Working Drafts of W3C XML Schema Definition Language (XSD) 1.1 Part 1: Structures and Part 2: Datatypes.

2008-06-05: The Semantic Web Health Care and Life Sciences Interest Group has published two Group Notes: A Prototype Knowledge Base for the Life Sciences and Experiences with the conversion of SenseLab databases to RDF/OWL. The former describes a prototype of a biomedical knowledge base that integrates 15 distinct data sources using currently available Semantic Web technologies including RDF and OWL. The Note outlines which resources were integrated, how the knowledge base was constructed using free and open source triple store technology, how it can be queried using SPARQL, and what resources and inferences are involved in answering complex queries. While the utility of the knowledge base is illustrated by identifying a set of genes involved in Alzheimer's Disease, the approach described here can be applied to any use case that integrates data from multiple domains. The second document describe the experience of converting SenseLab databases into OWL, an important step towards realizing the benefits of Semantic Web in integrative neuroscience research.
