Extensible Stylesheet Language (XSL) Requirements Version 2.0; Comments Welcome on First Public Draft

2008-03-26: The XSL Working Group has published the First Public Working Draft of Extensible Stylesheet Language (XSL) Requirements Version 2.0. This document enumerates the collected requirements for a 2.0 version of XSL Formatting Objects (XSL-FO), not for XSLT. XSL-FO is widely deployed in industry and academia where multiple output forms (typically print and online) are needed from single source XML. It is used in many diverse applications and countries on a large number of implementations to create technical documentation, reports and contracts, terms and conditions, invoices and other forms processing, such as driver's licenses and postal forms. The XSL Working Group invites people to help prioritize the feature set of XSL 2.0 by completing a survey until the end of September 2008. Learn more about the W3C XML Activity. (Permalink)

XQuery Scripting Extension 1.0 and Use Cases; Comments on First Public Drafts Welcome

2008-03-28: The XML Query Working Group has published two First Public Working Drafts: XQuery Scripting Extension 1.0 and XQuery Scripting Extension 1.0 Use Cases. The former defines an extension to XQuery 1.0 and XQuery Update Facility. Expressions can be evaluated in a specific order, with later expressions seeing the effects of the expressions that came before them. This specification introduces the concept of a block with local variable declarations, as well as several new kinds of expressions, including assignment, while, continue, break, and exit expressions. The latter specification includes the usage scenarios that motivate the changes in the former. Learn more about the Extensible Markup Language (XML) Activity. (Permalink)

Last Call: Basic XML Schema Patterns for Databinding Version 1.0

2008-03-28: The XML Schema Patterns for Databinding Working Group has published two documents: the Last Call Working Draft of Basic XML Schema Patterns for Databinding Version 1.0 and an ordinary Working Draft of Advanced XML Schema Patterns for Databinding Version 1.0. The first specification provides a set of basic XML Schema 1.0 patterns known to be interoperable between state of the art databinding implementations.The patterns may be used to describe XML 1.0 representations of commonly used data structures. Last Call comments are welcome through 30 April. The second specification provides a set of commonly used XML Schema 1.0 patterns known to cause issues with some state of the art databinding implementations.

Efficient XML Interchange (EXI) Format 1.0

2008-03-27: The Efficient XML Interchange Working Group has published a Working Draft of Efficient XML Interchange (EXI) Format 1.0. This document is the specification of 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.

XML Query (XQuery) 1.1 Use Cases

2008-03-27: The XML Query Working Group has published the First Public Working Draft of XML Query (XQuery) 1.1 Use Cases. This document specifies usage scenarios for XML Query (XQuery) 1.1, to illustrate important applications for the query language. Each use case is focused on a specific application area, and contains a Document Type Definition (DTD) and example input data. Each use case specifies a set of queries that might be applied to the input data, and the expected results for each query. See changes from the previous draft and learn more about the Extensible Markup Language (XML) Activity. (Permalink)

W3C Staff to Participate in Research on Privacy and Identity Management

2008-03-27: Privacy assures autonomy of the individual, a necessary precondition for a democratic society. W3C is pleased to announce the launch of the PrimeLife research project. W3C Staff members Thomas Roessler and Rigo Wenning will participate in this three-year, 10 Million Euro multi-partner research effort. The goal of the project is to develop scalable tools to help people protect their privacy and manage their identities in new and emerging services and applications (such as virtual communities and collaborative applications).

Call for Review: XML Signature Syntax and Processing (Second Edition) Proposed Edited Recommendation

2008-03-26: The XML Security Specifications Maintenance Working Group has published the Proposed Edited Recommendation of XML Signature Syntax and Processing (Second Edition). This document specifies XML digital signature processing rules and syntax. XML Signatures provide integrity, message authentication, and/or signer authentication services for data of any type, whether located within the XML that includes the signature or elsewhere. Read the list of changes and the implementation report. Comments are welcome through 30 April. Learn more about the Security Activity. (Permalink)

Protocol for Web Description Resources (POWDER): Grouping of Resources

2008-03-26: The Protocol for Web Description Resources (POWDER) Working Group has published a Working Draft of Protocol for Web Description Resources (POWDER): Grouping of Resources. The purpose of the Protocol for Web Description Resources (POWDER) is to provide a means to describe a group of resources through the publication of machine-readable metadata, as motivated by the POWDER Use Cases. The current document sets out how Description Resources (DRs) can be created and published, whether individually or as bulk data, how to link to DRs from other online resources, and, crucially, how DRs may be authenticated and trusted. The aim is to provide a platform through which opinions, claims and assertions about online resources can be expressed by people and exchanged by machines.

Internationalization Tag Set Interest Group Launched

2008-03-26: W3C is pleased to announce the launch of the Internationalization Tag Set (ITS) Interest Group, chaired by Yves Savourel (ENLASO Corporation). The ITS IG is a forum to foster a community of users of the Internationalization Tag Set (ITS), by promoting its adoption, and gathering information on its further development. The ITS defines data categories that may be used with schemas to support the internationalization and localization of schemas and documents. Participation in the new ITS IG is open to W3C Members and the public. Read about the W3C Internationalization Activity. (Permalink)
