On 18 June the MultilingualWeb-LT Working Group holds a showcase event in Dublin about the upcoming Internationalization Tag Set (ITS) 2.0 specification. Group participants demonstrate implementations for authoring ITS 2.0 data categories, for using them in localization workflows, and for improving machine translation or other language technology processes with ITS 2.0. Participation is free, but registration is required.

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 paperby 30 June 2013.

The MultilingualWeb-LT Working Group has published a second Last Call working draft of Internationalization Tag Set (ITS) 2.0.

The draft implements all changes since the previous publication of 11 April 2013. There are no remaining open issues. The Working Group is planning to finalize ITS 2.0 now: this is your last time to provide feedback! The Last Call period ends 11 June.

ITS 2.0 provides metadata to foster the adoption of the multilingual Web.

The JSON-LD Community Group and the RDF Working Group have announced the 2nd Last Call publication of the JSON-LD 1.0: Algorithms and APIspecification.

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 format has already been adopted by large companies such as Google in their Gmail productand is available to over 425 million customers around the world.

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. 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 2nd Last Call publication for the JSON-LD 1.0 Algorithms and API specification. Changes since the previous publication include a shift to use a Future’s based API design approach, better base URL processing, and better translation of data from RDF.
All substantive technical work on the specification is complete. Feedback on both specifications is encouraged and should be sent to public-rdf-comments@w3.org. The 2nd Last Call period will end in 3 weeks, on June 06th 2013.

If you would like to learn more about JSON-LD, there is a helpful introductory video on the topic as well as the json-ld.orgwebsite.

A report summarizing the MultilingualWeb workshop in Romeis now available from the MultilingualWeb site. It contains a summary of each session with links to presentation slides and more detailed scribing done on site in Rome. Links to video for each session will be posted soon.

With approximately 150 attendees, the Rome Workshop focused on the theme “Making the Multilingual Web Work” and emphasized information about the best practices and standards that help content creators and localizers ensure that the World-Wide Web lives up to its name, across boundaries of language and culture. Attendees heard from a variety of perspectives, with fruitful dialogue between various stakeholder groups involved in trying to expand the multilingual scope of the Web.

Taking place over two days (12 and 13 March, 2013) at the headquarters of the UN’s Food and Agriculture Organization (FAO), the Workshop featured twenty-four conference-style presentations, seven poster presentations, and an “open space” discussion that featured six breakout sessions focusing on key topics that emerged during the Workshop. In addition, it showcased technology implementations of the forthcoming internationalization Tag Set (ITS) 2.0 standard.

The Workshop was sponsored by the EU-funded QTLaunchPad project and Verisign . It was run by the MultilingualWeb-LT Working Group.

The Semantic Web Interest Group has published a new draft for the vCard-in-RDF Ontology , edited by Renato Iannella and James McKinney. The new draft updates the previous version by aligning it with the latest IETF vCard specification, ie, RFC6350.

This is a draft; If you wish to make comments regarding this document, please send them to semantic-web@w3.org ( subscribe , archives). The goal is to publish an Interest Group Note once there is a consensus in the community.

Stefan Schumacher published a German translation of the  “RDFa 1.1 Core”, under the title  “RDFa 1.1 Core”.

上綱 秀治 (Shuji Kamitsuna) published a Japanese translation of the  “SPARQL 1.1 Overview”, under the title  “SPARQL 1.1概要”.
