Frederick Hirsch, Nokia
Chair, W3C DAP Working Group


For your information, the Device APIs Working Group (DAP) [0] has just published a set of Working Group Notes stating work on certain  Recommendation track publications has been discontinued and that they should not be referenced or used as a basis for implementations.

No further action is required on your part.

The specifications are the Messaging API, System Information API, Pick  Contacts, Calendar, Pick Media Intent, and "Web Intents Addendum - Local  Services":


The primary reason for discontinuing the work has been concerns related to privacy and security for a general web API with no generalized  security/privacy model.

The Messaging API was defined to enable API access to a variety of  messaging mechanisms, including SMS, MMS and e-mail. While working on this  specification the DAP WG reduced the functionality to address security  concerns, reducing the scope to the point where the group decided to  discontinue the work.

The "System Information API" provided a wide variety of information about  the user interface in one specification, including sensors, power, network  interfaces and other information. While working on this specification the  Device APIs Working Group decided there would be advantages to working on  specifications focused on specific modules, enabling faster specification  development, reduced scope of testing as well as the potential for reduced  privacy and security attack surfaces. Work on the System Information API  specification was discontinued in favor of the current modular  specifications, including the Battery Status API [1] , Ambient Light  Events [2], Proximity Events [3], and the Vibration API [4] .

Based on community feedback the DAP WG attempted a shift from a device  centric security model to a general web approach, based on Web Intents  [5], a user-mediated model that offered a generic and promising approach.  Once implementers discovered issues with this underlying approach and  discontinued support, the DAP WG discontinued work on these  specifications, realizing more experience is needed before  standardization. The specifications in this category included Contacts  (Pick Contacts), Calendar (planned to follow Contacts approach), Gallery  (Pick Media Intent), and the "Web Intents Addendum - Local Services".

This set of Note publications is intended to provide clarity for these  publications in the TR space.

The areas of work for these deliverables remain in the scope of the DAP  working group charter, so if the DAP WG receives new information or  interest, it may resume work on a new version of those items. Currently  
there is no plan to continue work on these deliverables. In addition, the  System Applications WG has work related to contacts and messaging on its  roadmap [6].

Thank you,
