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 and the Ubiquitous Web Applications 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).

Highlights Since the Previous Advisory Committee Meeting

The Geolocation Working Group's First Public Draft Geolocation API specification was published on 22 December 2008.
W3C Workshop on Security for Access to Device APIs was held in London on 10-11 December 2008, hosted by Vodafone.. See the Workshop Report
A UWA Working Group Note on Personalization has been approved for publication
The Model-Based UI Incubator Group, a spin off from the UWA WG, is now up and running. This was set up to study the potential of model-based approaches for authoring of Web applications, drawing upon ten years plus of research.

Upcoming Activity Highlights

Last Call Working Draft for the Geolocation API
Last Call Working Draft on the Delivery Context Ontology together with a Working Group Note for an associated primer
Working Group Note on terminology, use cases and requirements for device coordination
Further work on exposing the Delivery Context Ontology and combining it with markup languages such as XHTML and SVG
