W3C today published the report of the Workshop on Data and Services Integration, hosted on 20-21 October 2011 by MITRE in Bedford, Massachusetts, USA. This workshop provided a way for the community to meet and discuss some of the challenges of integration of heterogeneous data and services. With the emergence of the Web, the need for reusing data and services has become even stronger as the number of available services has grown. Different services stacks now exist from Web Services to Cloud-based services. One goal of this workshop was to figure out the needs in the domain of integration that would benefit from standardization, or where discussion via Community or Business Groups could gather a critical mass.

The participants came to the conclusion that solutions to the data integration issues can be the result of better integration of tools helping going cross-stacks. They also discussed how to architect RESTful services in the enterprise, with a plan to create a group to work on Linked Data Patterns, specifically REST-based patterns on RDF and other formats.

The Media Analysis Management Interface Incubator Group published its final report, Media Analysis Management Interface XG Final Report. The Media Analysis Management Interface (MAMI) enables the understanding of the real world at a low cost by using analysis engines such as video image processing engines, sensor data analysis engines, and so on. It also enables various services to be easily provided, such as physical security, environmental load reduction, and intelligent accessibility services. The MAMI Incubator Group described the requirements of the MAMI and six use cases in three fields: energy saving, video surveillance, and operational improvement. The Incubator Group expects to collaborate with other W3C working groups, in particular the Multimodal Interaction Working Group.

This publication is part of the Incubator Activity. This work is not on the W3C standards track.

The Multimodal Interaction Working Group has published a Group Note: MMI interoperability test report. This document describes an interoperability test, executed by various members of the Multimodal Interaction Working Group, to demonstrate interoperability of multimodal components which are implementing the "Multimodal Architecture and Interfaces" specification.

The XML Processing Model Working Group has published a Last Call Working Draft of XML processor profiles. This specification defines several XML processor profiles, each of which defines how any given XML document should be processed, both operationally and in terms of what information must be made available to applications. It is intended as a resource for other specifications, which can by a single normative reference establish precisely what input processing they require as well as what information they require. Comments are welcome through 29 February. Learn more about the Extensible Markup Language (XML) Activity.

The XML Security Working Group invites implementation of three Candidate Recommendations: XML Signature Syntax and Processing Version 2.0, Canonical XML Version 2.0, and XML Signature Streaming Profile of XPath 1.0. 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 XML Security 2.0 specifications are designed to update the XML Signature and Canonical XML specifications to improve performance, streaming support, robustness, and reduced attack surface.

The Working Group has also published a W3C Note: XML Security RELAX NG Schemas, a document that provides RELAX NG schemas corresponding to the normative XSD schemas for XML Signature 1.1, XML Encryption 1.1, and related specifications.

To address patent disclosures related to the XML Signature 1.1 and XML Encryption 1.1 specifications, W3C has chartered a Patent Advisory Group. Concerns related to XML Signature 1.1 may also apply to XML Signature 2.0.

The XML Schema Working Group has published Proposed Recommendations of two specifications: W3C XML Schema Definition Language (XSD) 1.1 Part 1: Structures, W3C XML Schema Definition Language (XSD) 1.1 Part 2: Datatypes. The former specifies the XML Schema Definition Language, which offers facilities for describing the structure and constraining the contents of XML documents, including those which exploit the XML Namespace facility. The schema language, which is itself represented in an XML vocabulary and uses namespaces, substantially reconstructs and considerably extends the capabilities found in XML document type definitions (DTDs). This specification depends on XML Schema Definition Language 1.1 Part 2: Datatypes, which defines facilities for defining datatypes to be used in XML Schemas as well as other XML specifications. The datatype language, which is itself represented in XML, provides a superset of the capabilities found in XML document type definitions (DTDs) for specifying datatypes on elements and attributes. Comments are welcome through 20 February. Learn more about the Extensible Markup Language (XML) Activity.

The XML Print and Page Layout Working Group has published a Working Draft of Extensible Stylesheet Language (XSL) Version 2.0. XSL-FO is an XML vocabulary that uses CSS and additional properties for formatting documents to paged media. Learn more about the Extensible Markup Language (XML) Activity.
