W3C is pleased to announce the creation of the Library Linked Data Incubator Group, whose mission is to help increase global interoperability of library data on the Web, by bringing together people involved in Semantic Web activities - focusing on Linked Data - in the library community and beyond, building on existing initiatives, and identifying collaboration tracks for the future. The following W3C Members have sponsored the charter for this group: Helsinki University of Technology, DERI Galway, Competence Centre for Interoperable Metadata (KIM), Library of Congress, Los Alamos National Laboratory, MIMOS, OCLC, Talis, University of Applied Sciences Potsdam, and Vrije Universiteit Amsterdam. Read more about the Incubator Activity, an initiative to foster development of emerging Web-related technologies. Incubator Activity work is not on the W3C standards track but in many cases serves as a starting point for a future Working Group.

The XML Processing Model Working Group has published the First Public Working Draft of XML processor profiles. This specification defines several XML processor profiles, each of which fully determines a data model for any given XML document. It is intended as a resource for other specifications, which can by a single normative reference establish precisely what input processing they require. Learn more about the Extensible Markup Language (XML) Activity.

The XML Security Working Group has published three Last Call Working Drafts: XML Encryption Syntax and Processing Version 1.1, XML Signature Syntax and Processing Version 1.1, and XML Security Generic Hybrid Ciphers. The group also published a Working Draft of XML Security Algorithm Cross-Reference. XML Encryption specifies a process for encrypting data and representing the result in XML. XML Signatures provide integrity, message authentication, and/or signer authentication services for data of any type, whether located within the XML that includes the signature or elsewhere. The third document augments XML Encryption by defining algorithms, XML types and elements necessary to enable use of generic hybrid ciphers in XML Security applications. The final document summarizes XML Security algorithm URI identifiers and the specifications associated with them. Last Call comments are welcome through 10 June.

The Voice Browser Working Group has published a Working Draft of State Chart XML (SCXML): State Machine Notation for Control Abstraction. SCXML is a general-purpose event-based state machine language that can be used in many ways. It can be used as a high-level dialog language controlling VoiceXML 3.0's encapsulated speech modules. It can also be used as a voice application metalanguage, where in addition to VoiceXML 3.0 functionality, it may also control database access and business logic modules.
