Status of the Document


This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.

This document was published by the Second Screen Presentation Working Group as a Candidate Recommendation. This document is intended to become a W3C Recommendation. If you wish to make comments regarding this document, please send them to public-secondscreen@w3.org (subscribe, archives). W3C publishes a Candidate Recommendation to indicate that the document is believed to be stable and to encourage implementation by the developer community. This Candidate Recommendation is expected to advance to Proposed Recommendation no earlier than 12 September 2016. All comments are welcome.

Please see the Working Group's implementation report.

Since publication as Working Draft on 10 May 2016, the Working Group has added a new URL fallback mechanism for requests to initiate or reconnect to a presentation, re-written the algorithm to create a receiving browsing context, clarified interactions between iframes and the sandboxing flag, and resolved to postpone new features currently mentioned in the group's issue tracker to a possible future version. The Working Group also made further progress on the test suite.

No feature has been identified as being at risk. However, the working group notes that it expects the definitions in the 6.8 Sandboxing and the allow-presentation keyword section to be integrated in HTML (see issue #437 in the Web Platform Working Group issue tracker) and dropped from this specification.

The Second Screen Presentation Working Group will complete the test suite for the Presentation API during the Candidate Recommendation period and update the preliminary implementation report. For this specification to advance to Proposed Recommendation, two independent, interoperable implementations of each feature must be demonstrated, as detailed in the CR exit criteria section.

Publication as a Candidate Recommendation does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
