Mission

As defined in its charter, the mission of the Device APIs Working Group is to create client-side APIs that enable the development of Web Applications and Web Widgets that interact with devices services such as Calendar, Contacts, Camera, etc.

Roadmap

As every Working Group, the Device APIs Working Group aims at gathering consensus on its specifications, both within the Working Group and with the community at large, working through an iterative process with implementors to ensure that the specifications are implementable and implemented.

The most recent working draft is highlighted as follows in the table below (it may be a working draft that was updated following a Last Call, for example).

As part of its technical work, the group ensures that its APIs are reviewed according to a checklist of good practices for APIs.

The history and past revisions of the documents drafts are available in the W3C public CVS server.

We use the W3C Github Web Platform Tests repository to manage our test suites, whose latest versions are available on W3C Test Server, w3c-test.org.

The Working Group has currently shelved the following work items, waiting for a better overall approach to emerge:

The Working Group is not planning to work on the following items:

APIs that have been suggested as worth consideration for the group but not currently prioritised (and therefore not up for discussion) are kept in the FutureWork page on the group's wiki.

See also coordination points with the Web Applications Working Group.

Media Capture Task Force

This is a joint activity of the Device APIs Working Group and the Web Real-Time Communications Working Group. The work on the media capture API getUserMedia is done on the publicly archived mailing list: <public-media-capture@w3.org>. Additional information is available on the Media Capture Wiki.

Web Intents Task Force

This is a joint activity of the Device APIs Working Group and the Web Applications Working Group. The aim is to review the Web Intents proposal and to see whether it can be adapted to support additional use cases for service discovery, e.g. those of the Web & TV Interest Group. The work on Web Intents is done in the Web Intents task force on the publicly archived mailing list: <public-web-intents@w3.org>. Additional information is available on the Web Intents Wiki.

History

The Working Group was first chartered in July 2009 as the “Device APIs & Policy Working Group”, as a follow-up to the workshop on Security for Access to Device APIs from the Web held in December 2008, and then rechartered in August 2011 under the name “Device APIs Working Group”.

The group used to work on the following documents, but their development has been stopped:

The following were submitted as starting points for this group's deliverables:
