This document defines platform and language neutral programming interfaces that provide Web applications access to a hierarchy of dynamic properties representing device capabilities, configurations, user preferences and environmental conditions.
The Delivery Context Ontology provides a formal model of the characteristics of the environment in which devices interact with the Web or other services. The delivery context includes the characteristics of the device, the software used to access the service and the network providing the connection among others.
The delivery context is an important source of information that can be used to adapt materials 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.
The core, normative sections and examples of this document are generated automatically from the ontology itself.
