RDF Validation Workshop - Practical Assurances for Quality RDF Data

Coralie Mercier — 2013-05-22T09:54:58-05:00

W3C announced today a RDF Validation Workshop - Practical Assurances for Quality RDF Data, 10-11 September 2013, in Cambridge, USA. The Semantic Web has demonstrated considerable value for collaborative contributions to data. Adoption in many mission-critical environments requires data to conform to specified patterns. Validation in a banking context shares many requirements with quality assurance of linked clinical data. Systems like Linked Open Data, which don't have formal interface specifications, share these validation needs. Most data representation languages used in conventional settings offer some sort of input validation, ranging from parsing grammars for domain-specific languages to XML Schema or RelaxNG for XML structures. While the distributed nature of RDF affects the notions of "validity", tool chains need to be established to ensure data integrity. The goal of this workshop is to discuss use cases for data validation on the Semantic Web with development of technologies to enable those use cases. W3C membership is not required to participate. The event is open to all. All participants are required to submit a position paper by 30 June 2013.

Updated Candidate Recommendation of XPath and XQuery Functions and Operators 3.0

Coralie Mercier — 2013-05-21T07:24:29-05:00

The XML Query Working Group and the XSLT Working Group have published a new version of the Candidate Recommendation of XPath and XQuery Functions and Operators 3.0. The new version reflects changes and clarifications that have been made during the CR period, primarily as a result of feedback from implementors outside the two Working Groups. The document describes various functions and operators that work on XML Schema-compatible data types for use in XPath, XSLT, XQuery, XQueryX, SPARQL and other languages. Learn more about the Extensible Markup Language (XML) Activity.

Last Call: Internationalization Tag Set (ITS) Version 2.0

Coralie Mercier — 2013-05-21T07:10:33-05:00

The MultilingualWeb-LT Working Group has published a Last Call Working Draft of Internationalization Tag Set (ITS) Version 2.0. The Internationalization Tag Set (ITS) 2.0 enhances the foundation to integrate automated processing of human language into core Web technologies. ITS 2.0 provides metadata to foster the adoption of the multilingual Web. The draft reflects all changes since the first last call publication. Comments are welcome through 11 June.

W3C Workshop on Social Standards: The Future of Business

Coralie Mercier — 2013-05-16T09:08:45-05:00

W3C announced today a Workshop on Social Standards: The Future of Business, 7-8 August 2013, in San Francisco, USA. The event is hosted by AppFusions, sponsored by IBM, and jointly organized with the OpenSocial Foundation. The goal of this workshop is to bring together social business experts and social technology experts to discuss the use-cases that existing specifications and standards don't adequately address, and understand where new standards are needed. This Workshop is open in particular to social business leaders and strategists, federated and decentralized social Web technologists, security experts, and developers. W3C membership is not required to participate. The event is open to all. All participants are required to submit a position paper by 1 July 2013.

W3C Workshop Report on the MultilingualWeb workshop in Rome

Coralie Mercier — 2013-05-16T09:00:10-05:00

A report summarizing the MultilingualWeb workshop in Rome is now available from the MultilingualWeb site. It contains a summary of each session with links to presentation slides and minutes taken during the workshop in Rome. The workshop was a huge success, with approximately 150 participants, focus sessions on topics like Internationalized Domain Names, Best Practices for Multilingual Linked Open Data (BP-MLOD) and an implementation showcase of the upcoming ITS 2.0 specification. The Workshop was hosted by FAO, sponsored by the EU-funded QTLaunchPad project and by Verisign. A new workshop in the MultilingualWeb series is planned for 2014.

Last Call: JSON-LD 1.0 Processing Algorithms and API

Coralie Mercier — 2013-05-16T08:58:33-05:00

The RDF Working Group has published a Last Call Working Draft of JSON-LD 1.0 Processing Algorithms and API. This specification defines an Application Programming Interface (API) and a set of algorithms for programmatic transformations of JSON-LD documents. Restructuring data according the defined transformations often dramatically simplifies its usage. Comments are welcome through 06 June. Learn more about the Semantic Web Activity.

Last Call: Indexed Database API

Coralie Mercier — 2013-05-16T08:53:57-05:00

The Web Applications Working Group has published a Last Call Working Draft of Indexed Database API. This document defines APIs for a database of records holding simple values and hierarchical objects. Each record consists of a key and some value. Moreover, the database maintains indexes over records it stores. An application developer directly uses an API to locate records either by their key or by using an index. A query language can be layered on this API. An indexed database can be implemented using a persistent B-tree data structure. Comments are welcome through 07 June. Learn more about the Rich Web Client Activity.

Two Drafts Published by the System Applications Working Group

Coralie Mercier — 2013-05-16T08:51:11-05:00

The System Applications Working Group has published two Working Drafts today:

The app: URI scheme. This specification defines the app: URI scheme and rules for dereferencing an app: URI, which can be used to address resources inside a package (e.g., a packaged application). The dereferencing model relies on HTTP semantics to return resources in a manner akin to a HTTP GET request. Doing so allows this URI scheme to be used with other technologies that rely on HTTP responses to function as intended, such as XHR.
Messaging API. This specification defines a System Level API which offers a simple interface to get access to mobile messaging services. A typical use case of the Messaging API is the implementation of a messaging client application that allows the user to send SMS and MMS messages as well as to access and manage the received SMS and MMS messages.
