Four POWDER Documents published; three Last Call Drafts

2008-11-17: The Protocol for Web Description Resources (POWDER) Working Group published four Working Drafts today. The purpose of the Protocol for Web Description Resources (POWDER) is to provide a means for individuals or organizations to describe a group of resources through the publication of machine-readable metadata.

  • Description Resources (Last Call); which details the creation and lifecycle of Description Resources (DRs), which encapsulate metadata
  • Grouping of Resources (Last Call); which describes how sets of IRIs can be defined such that descriptions or other data can be applied to the resources obtained by dereferencing IRIs that are elements of the set.
  • Formal Semantics (Last Call); which describes how the relatively simple operational format of a POWDER document can be transformed for processing by Semantic Web tools
  • Primer (First Public Draft)

Last Call comments are welcome through 5 December. Learn more about the Semantic Web Activity. (Permalink)

XML Signature Best Practices First Public Draft

2008-11-17: The XML Security Working Group has published the First Public Working Draft of XML Signature Best Practices. This document collects best practices for implementors and users of the XML Signature specification. 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, for example.

W3C Publishes XML Signature Best Practices First Public Draft

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.

Last Call: Selectors API

2008-11-14: The Web Applications Working Group has published the Last Call Working Draft of Selectors API. Selectors, which are widely used in CSS, are patterns that match against elements in a tree structure. The Selectors API specification defines methods for retrieving Element nodes from the DOM by matching against a group of selectors. It is often desirable to perform DOM operations on a specific set of elements in a document. These methods simplify the process of acquiring specific elements, especially compared with the more verbose techniques defined and used in the past. Comments are welcome through 12 December.
