RIF Standard Supports Data Integration, Enterprise Agility
22 June 2010 | Archive
Today W3C published a new standard for building rule systems on the Web. Declarative rules allow integration and transformation of data from multiple sources in a distributed, transparent and scalable manner. The new standard, called Rule Interchange Format (RIF), was developed with participation from the Business Rules, Logic Programming, and Semantic Web communities to provide interoperability and portability between many different systems using declarative technologies. For more information, see the RIF FAQ.
The six new standards are:
- RIF Core Dialect, which provides a standard, base level of functionality for interchange
- RIF Basic Logic Dialect and RIF Production Rule Dialect provided extended functionality matching two common classes of rule engines
- RIF Framework for Logic Dialects describes how to extend RIF for use with a large class of systems
- RIF Datatypes and Built-Ins 1.0 borrows heavily from XQuery and XPath for a set of basic operations
- and RIF RDF and OWL Compatibility specifies how RIF works with RDF data and OWL ontologies.
Along with these standards, W3C today published five related documents: RIF Overview, RIF Test Cases, OWL 2 RL in RIF, RIF Combination with XML data, and RIF In RDF. The RIF Working Group is also preparing a primer and a revision of its outdated Use Cases and Requirements. Learn more about the Semantic Web Activity.
HTML Progresses with Eight Drafts; Two New
25 June 2010 | Archive
The HTML Working Group published eight documents:
- Updated Working Drafts of the HTML5 specification, the accompanying explanatory document HTML5 differences from HTML4, and the related non-normative reference HTML: The Markup Language.
- Updated Working Drafts of the specifications HTML+RDFa 1.1 and HTML Microdata, which define mechanisms for embedding machine-readable data in HTML documents, and the specification HTML Canvas 2D Context, which defines a 2D immediate-mode graphics API for use with the HTML5 <canvas> element.
- New! HTML5: Techniques for providing useful text alternatives, a First Public Working Draft which is intended to help authors provide useful text alternatives for images in HTML documents.
- New! Polyglot Markup: HTML-Compatible XHTML Documents, a First Public Working Draft which is intended to help authors produce XHTML documents that are also compatible with non-XML HTML syntax and parsing rules.

Last Call: Media Fragments URI 1.0
24 June 2010 | Archive
The Media Fragments Working Group has published a Last Call Working Draft of Media Fragments URI 1.0. This document describes the Media Fragments 1.0 specification. It specifies the syntax for constructing media fragment URIs and explains how to handle them when used over the HTTP protocol. The syntax is based on the specification of particular field-value pairs that can be used in URI fragment and URI query requests to restrict a media resource to a certain fragment. Comments are welcome through 27 August. Learn more about the Video in the Web Activity.
Call for Review: Web Security Context: User Interface Guidelines Proposed Recommendation Published
22 June 2010 | Archive
The Web Security Context Working Group has published a Proposed Recommendation 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 user agents as well as recommendations on conveying error situations in security protocols. Comments are welcome through 20 July. Learn more about the Security Activity.
W3C Invites Implementations of Digital Signatures for Widgets; 'view-mode' Media Feature
22 June 2010 | Archive
The Web Applications Working Group invites implementation of two Candidate Recommendations: Digital Signatures for Widgets and The 'view-mode' Media Feature. The first defines a profile of the XML Signature Syntax and Processing 1.1 specification to allow a widget package to be digitally signed. Widget authors and distributors can digitally sign widgets as a mechanism to ensure continuity of authorship and distributorship; follow the implementation report. The second specification defines a media feature to match the different visual presentation modes that can be applied to web applications and thereby apply different styling based on these different modes using CSS Media Queries; follow the implementation report.

Last Call: Scalable Vector Graphics (SVG) 1.1 (Second Edition)
22 June 2010 | Archive
The SVG Working Group has published a Last Call Working Draft of Scalable Vector Graphics (SVG) 1.1 (Second Edition). This specification defines the features and syntax for Scalable Vector Graphics (SVG) Version 1.1, a modularized language for describing two-dimensional vector and mixed vector/raster graphics in XML. This specification incorporates SVG 1.1 errata. Comments are welcome through 13 July. Learn more about the Graphics Activity.
