UWA

The Ubiquitous Web Applications Activity was launched on 30 March 2007 with the vision of enabling value-added services and business models for ubiquitous networked devices, based upon W3C's strengths in declarative representations. The Activity includes the Geolocation Working Group, the Ubiquitous Web Applications Working Group and the Device APIs and Policy Working Group.

• The Geolocation Working Group is defining a secure and privacy-sensitive interface for using client-side location information in location-aware Web applications. A geolocation API for accessing device location is under development, and in addition, the Working Group may explore exposing location information via markup or HTTP headers. The Working Group is tasked with identifying and addressing requirements for security and privacy protection.
• The Ubiquitous Web Applications Working Group focuses on mechanisms to reduce the cost for developing and delivering applications to a wide range of devices, including the means to adapt to user preferences and environmental conditions. A key part of this work is the Delivery Context Ontology. Other work is addressing the role of Web technologies for distributed applications of consumer electronic devices (the Web of things).
• The Device APIs and Policy Working Group is creating client side programming interfaces to enable Web applications and widgets to access device services, including the calendar, contacts, camera, etc. The group will also provide a framework for expressing security policies to govern access to these APIs.

Highlights Since the Previous Advisory Committee Meeting

• The Geolocation Working Group's Last Call Working Draft Geolocation API specification was published on 7 July 2009.
• The UWA Working Group published the Delivery Context Ontology Last Call Working Draft on 16 June 2009. In addition a Working Group Note entitled W3C Personalization Roadmap was published on 9 April 2009.
• The Device APIs and Policy Working Group charter was approved, and the Group has begun holding regular meetings.

Upcoming Activity Highlights

• Candidate Recommendation for the Geolocation API
• Candidate Recommendation for the Delivery Context Ontology
• UWA Working Group recharter to focus on DCO, DIAL and DCCI deliverables with an emphasis on context awareness and personalization.
• First Public Working Drafts from the Device APIs and Policy Working Group, with an expected priority put on Filesystems and Personal Information Management APIs.
• The Model-based User Interfaces Incubator Group has requested a charter extension, and is planning to hold another workshop in 2010.
