Web Annotation Data Model and Vocabulary are W3C Candidate Recommendations

   22 November 2016
   <https://www.w3.org/blog/news/archives/5987>

   The Web Annotation Working Group has published a Candidate Recommendation for two documents:

   <https://www.w3.org/annotation/>
     * Web Annotation Data Model: This specification describes a structured model and format, in JSON, to enable annotations to be shared and reused across different hardware and software platforms. Common use cases can be modeled in a manner that is simple and convenient, while at the same time enabling more complex requirements, including linking arbitrary content to a particular data point or to segments of timed multimedia resources.
     * Web Annotation Vocabulary: This specifies the set of RDF classes, predicates and named entities that are used by the Web Annotation Data Model. It also lists recommended terms from other ontologies that are used in the model, and provides the JSON-LD Context and profile definitions needed to use the Web Annotation JSON serialization in a Linked Data context.

   This is a re-publication, without substantial change, of the Candidate Recommendation published on the 6th of September. The only significant change (beyond minor editorial clarifications and editorial changes) is that some features that are not expected to receive enough implementations to fulfill the exit criteria, have been moved into an informative appendix. No new features have been added and no normative features have been changed.

   <https://www.w3.org/blog/news/archives/5776>

   Candidate Recommendation means that the Working Group considers the technical design to be complete, and is seeking implementation feedbacks on the documents. There is a separate document how to use them and report on implementation results. The group is keen to get comments and implementation experiences on these specifications, either as issues on the Group’s GitHub repository or by posting to public-annotation@w3.org.

   <https://github.com/w3c/web-annotation-tests/blob/master/README.md>
   <https://github.com/w3c/web-annotation/issues>
   <mailto:public-annotation@w3.org>

   The group expects to satisfy the implementation goals (i.e., at least two, independent implementation for each of the test cases) by December 30, 2016.

First Public Working Draft: Pointer Lock 2.0

   22 November 2016
   <https://www.w3.org/blog/news/archives/5991>

   The Web Platform Working Group has published a First Public Working Draft of "Pointer Lock 2.0." This specification defines an API that provides scripted access to raw mouse movement data while locking the target of mouse events to a single element and removing the cursor from view. This is an essential input mode for certain classes of applications, especially first person perspective 3D applications and 3D modeling software. The new version of the specification introduces a few Shadow DOM accommodating changes.

W3C Invites Implementations of Page Visibility Level 2

   22 November 2016
   <https://www.w3.org/blog/news/archives/5993>

   The Web Performance Working Group invites implementation of the Candidate Recommendation of "Page Visibility Level 2." The Page Visibility API defines a means to programmatically determine the visibility state of a top level browsing context, and to be notified if the visibility state changes. This specification defines a means to programmatically determine the visibility state of a document. This can aid in the development of resource efficient web applications.

Workshops

     * 2016-11-30 (30 NOV) – 2016-12-01 ( 1 DEC)
       Smart Descriptions & Smarter Vocabularies (SDSVoc)
       <https://www.w3.org/2016/11/sdsvoc/>
       Amsterdam
       CWI with support from the VRE4EIC project
       The workshop will cover a variety of related issues: how to manage a vocabulary in a collaborative environment, how to define an application profile for human and machine consumption, how to request data using a specific profile and, as a prime example of all this - experiences of using "DCAT" that might lead to its extension.
