The W3C Ubiquitous Web Applications Working Group has posted the first working draft of Delivery Context Ontology:
The Delivery Context Ontology provides a formal model of the characteristics of the environment in which devices interact with the Web. The delivery context includes the characteristics of the device, the software used to access the Web and the network providing the connection among others.
The delivery context is an important source of information that can be used to adapt materials from the Web to make them useable on a wide range of different devices with different capabilities.
The ontology is formally specified in the Web Ontology Language [OWL]. This document describes the ontology and gives details of each property that it contains.
