Two upcoming W3C Workshops on Digital Publishing

09 April 2013 | Archive

W3C announced today two closely related workshops, part of the W3C headlights 2013 exercise on Digital Publishing:

  • eBooks & i18n: Richer Internationalization for eBooks on 4 June 2013 in Tokyo, Japan. This workshop will investigate international functionality that needs to be added to the Open Web Platform; the goal is to make the various eBook reading platforms suitable for electronic books that use the printing and typesetting traditions of different cultures. If you are interested in participating, please submit a position paper by 30 April 2013.
  • Publishing and the Open Web Platform on 16-17 September 2013 in Paris, France. This workshop will look at the "back-end" processing to make the Open Web Platform suitable for commercial publishing, especially in print, all the way from authoring through to delivering the printed product and beyond. If you are interested in participating, please submit a position paper by 1 July 2013.

Last Call: API for Media Resources 1.0

11 April 2013 | Archive

The Media Annotations Working Group has published a 3rd Last Call Working Draft of API for Media Resources 1.0. This specification 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. These properties are used as a pivot vocabulary in this API. The core of this specification is the definition of API interfaces for retrieving metadata information in synchronous and asynchronous. It also defines interfaces for structured return types along with the specification of the behavior of an API implementation. Comments are welcome through 03 June. Learn more about the Video in the Web Activity.

Last Call: JSON-LD 1.0, JSON-LD 1.0 Processing Algorithms and API

11 April 2013 | Archive

The RDF Working Group and the JSON-LD Community Group have published two Last Call Working Drafts today:

  • JSON-LD 1.0. JSON-LD harmonizes the representation of Linked Data in JSON by describing a common JSON representation format for expressing directed graphs; mixing both Linked Data and non-Linked Data in a single document. The syntax is designed to not disturb already deployed systems running on JSON, but provide a smooth upgrade path from JSON to JSON-LD. It is primarily intended to be a way to use Linked Data in Web-based programming environments, to build interoperable Linked Data Web services, and to store Linked Data in JSON-based storage engines. JSON-LD is capable of serializing any RDF graph or dataset and most, but not all, JSON-LD documents can be directly transformed to RDF.
  • JSON-LD 1.0: Algorithms and API. The JSON-LD 1.0 Algorithms and API specification describes useful Algorithms for working with JSON-LD data. It also specifies an Application Programming Interface that can be used to transform JSON-LD documents in order to make them easier to work with in programming environments like JavaScript, Python, and Ruby.

This is a Last Call publication for both specifications. All substantive technical work on the specification is complete. Feedback on both specifications is encouraged and should be sent to The Last Call period will end in 4 weeks, on May 10th 2013

Internationalization Tag Set (ITS) Version 2.0 Draft Published

11 April 2013 | Archive

The MultilingualWeb-LT Working Group has published an updated 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 changes since the last call publication 6 December 2012 and asks for feedback on the remaining open issues. Learn more about the Internationalization Activity.

Clipboard API and events Draft Published

11 April 2013 | Archive

The Web Applications Working Group has published a Working Draft of Clipboard API and events. This document describes APIs for clipboard operations such as copy, cut and paste in web applications. Learn more about the Rich Web Client Activity.

Call for Review: Web Storage Proposed Recommendation Published

09 April 2013 | Archive

The Web Applications Working Group has published a Proposed Recommendation of Web Storage. This specification defines an API for persistent data storage of key-value pair data in Web clients. Comments are welcome through 07 May. Learn more about the Rich Web Client Activity.

Working Drafts of RDF 1.1 Semantics and TriG, N-Triples and N-Quads published as Notes

09 April 2013 | Archive

The RDF Working Group has published two Working Drafts today:

  • RDF 1.1 Semantics. This document describes a precise semantics for the Resource Description Framework 1.1 and RDF Schema. It defines a number of distinct entailment regimes and corresponding systems of inference rules. It is part of a suite of documents which comprise the full specification of RDF 1.1.
  • TriG. This document defines a textual syntax for RDF called TriG that allows an RDF dataset to be completely written in a compact and natural text form, with abbreviations for common usage patterns and datatypes. TriG is an extension of the Turtle format.

The RDF Working Group also published two Group Notes today:

  • N-Triples. N-Triples is a line-based, plain text format for encoding an RDF graph.
  • N-Quads. N-Quads is a line-based, plain text format for encoding an RDF dataset.

Scalable Vector Graphics (SVG) 2 Draft Published

09 April 2013 | Archive

The SVG Working Group has published a Working Draft of Scalable Vector Graphics (SVG) 2. This specification defines the features and syntax for Scalable Vector Graphics (SVG) Version 2, a language for describing two-dimensional vector and mixed vector/raster graphics. Although an XML serialization is given, processing is defined in terms of a DOM. Learn more about the Graphics Activity.
