This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title links to the most recent version of a document.
W3C Recommendations have been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and are endorsed by the Director as Web Standards. Learn more about the W3C Recommendation Track.
Group Notes are not standards and do not have the same level of W3C endorsement.
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.
Below are draft documents: Candidate Recommendations, Last Call Drafts, other Working Drafts. Some of these may become Web Standards through the W3C Recommendation Track process. Others may be published as Group Notes or become obsolete specifications.
These specifications have either been superseded by others, or have been abandoned. They remain available for archival purposes, but are not intended to be used.
