The XSL Working Group has published the First Public Working Draft of Requirements and Use Cases for XSLT 2.1. This document is a characterization of requirements and use cases for XSL Transformations (XSLT) Version 2.1. The relative priorities to be assigned to these different enhancements are still being decided. W3C welcomes input to the XSL Working Group to help in that process.

The Math Working Group has published a Last Call Working Draft of Mathematical Markup Language (MathML) Version 3.0. MathML is an XML application for describing mathematical notation and capturing both its structure and content. The goal of MathML is to enable mathematics to be served, received, and processed on the World Wide Web, just as HTML has enabled this functionality for text. MathML can be used to encode both mathematical notation and mathematical content. About thirty-eight of the MathML tags describe abstract notational structures, while another about one hundred and seventy provide a way of unambiguously specifying the intended meaning of an expression. Comments are welcome through 01 July. Learn more about the Math Activity.

The RDB2RDF Working Group has published the First Public Working Draft of Use Cases and Requirements for Mapping Relational Databases to RDF. The need to share data with collaborators motivates custodians and users of relational databases (RDB) to expose relational data on the Web of Data. This document examines a set of use cases from science and industry, taking relational data and exposing it in patterns conforming to shared RDF schemata. These use cases expose a set of functional requirements for exposing relational data as RDF in the RDB2RDF Mapping Language (R2RML). Learn more about the Semantic Web Activity.

The Web Services Resource Access Working Group has published the First Public Working Draft of Web Services SOAP Assertions (WS-SOAPAssertions). This specification defines two WS-Policy assertions that can be used to advertise the requirement to use a certain version of SOAP in message exchanges. Learn more about the Web Services Activity.

The Cascading Style Sheets (CSS) Working Group has published a Working Draft of CSS Generated Content for Paged Media Module. This module describes features often used in printed publications. Most of the specified functionality involves some sort of generated content where content from the document is adorned, replicated, or moved in the final presentation of the document. Along with two other CSS3 modules - multi-column layout and paged media - this module offers advanced functionality for presenting structured documents on paged media. Learn more about the Style Activity.

The Media Annotations Working Group has published Last Call Working Drafts of Ontology for Media Resource 1.0 and API for Media Resource 1.0. The former document defines the Ontology for Media Resource 1.0. This ontology, or "core vocabulary," is meant to bridge the different descriptions of media resources on the Web, as opposed to media resources in local archives or musea. It is defined based on a core set of properties which covers basic metadata to describe media resources. The ontology is designed to foster the interoperability among various kinds of metadata formats currently used to describe media resources on the Web. The latter specification defines a client-side API to access metadata information related to media resources on the Web. Comments are welcome through 11 July.
