Six RIF Working Drafts Published; Last Call for Basic Logic Dialect and RDF-OWL
2008-08-01: The Rule Interchange Format (RIF) Working Group published six documents yesterday:
* RIF Basic Logic Dialect (Last Call)
* RIF RDF and OWL Compatibility (Last Call)
* RIF Framework for Logic Dialects
* RIF Use Cases and Requirements
* RIF Production Rule Dialect (First Public Draft)
* RIF Datatypes and Built-Ins 1.0
"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.

Last Call: Content Transformation Guidelines 1.0
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.

Last Call: CSS Marquee Module Level 3
2008-08-01: The Cascading Style Sheets (CSS) Working Group has published a Last Call Working Draft of CSS Marquee Module Level 3. CSS describes the rendering of documents on various media. 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 Septembeer.
