Media Source Extensions™ is a W3C Recommendation
17 November 2016 | Archive
The HTML Media Extensions Working Group has published a W3C Recommendation for Media Source Extensions™. This specification fulfills a vital part of putting video on the Web by extending the HTML5 video capabilities and facilitating a variety of use cases like adaptive streaming, time shifting and video editing, as well as 360° video players. Flexible and powerful, Media Source Extensions™ provides commercial quality IP streaming video for Web applications, across different platforms and between unrelated companies, and is already deployed in major browsers and video services, such as Youtube.

Web Annotation Data Model and Vocabulary are W3C Candidate Recommendations
22 November 2016 | Archive
The Web Annotation Working Group has published a Candidate Recommendation for two documents:
- 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.
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.
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.

W3C Workshop Report: Web & Virtual Reality
17 November 2016 | Archive
W3C published today the report of the
W3C Workshop on Web & Virtual Reality held on October 19-20 2016 in San
Jose, California, USA. During the workshop, 120 participants
representing browser vendors, headset and hardware manufacturers, VR
content providers, designers and distributors analyzed the opportunities
provided by making the Web a full-fledged platform for VR experiences.
They recognized the strong prospects already opened by existing and
in-development Web APIs, in particular the WebVR API that
was highlighted as an important target for near-term standardization, as
well as the high priority of making the Web a primary platform for
distributing 360° videos. They also identified new
opportunities that would be brought by enabling traditional Web pages to
be enhanceable as immersive spaces, and in the longer
term, by making 3D content a basic brick available to Web developers and
content aggregators.
