The Media Annotations Working Group published a Recommendation of Metadata API for Media Resources 1.0. This document defines an API to access metadata information related to media resources on the Web. The overall purpose is to provide developers with a convenient access to metadata information stored in different metadata formats. The API provides means to access the set of metadata properties defined in the Ontology for Media Resources 1.0 specification. Learn more about the Video on the Web Activity.

The Voice Browser Working Group invites implementation of the Candidate Recommendation of State Chart XML (SCXML): State Machine Notation for Control Abstraction.

The Linked Data Platform (LDP) Working Group has published a Group Note of Linked Data Platform Use Cases and Requirements. To foster the development of the Linked Data Platform specification, this document includes a set of user stories, use cases, scenarios and requirements that motivate a simple read-write Linked Data architecture, based on HTTP access to web resources that describe their state using RDF. The aim throughout has been to avoid details of protocol (specifically the HTTP protocol), and use of any specific vocabulary that might be introduced by the LDP specification.

The Digital Publishing Interest Group has published two First Public Working Drafts today:

• Annotation Use Cases, which describes the set of use cases generated for Annotation and Social Reading within the W3C Digital Publishing Interest Group, in coordination with the Open Annotation Community Group.
• Requirements for Latin Text Layout and Pagination, which describes requirements for pagination and layout of books in latin languages, based on the tradition of print book design and composition. It is hoped that these principles can inform the pagination of digital content as well, and serve as a reference for the CSS Working Group and other interested parties. This work was inspired by JLREQ.
