Submission Request to W3C: OWL 1.1 Web Ontology Language

We, W3C members:

  1. SRI International (AC rep: David Martin),
  2. TopQuadrant (AC rep: Ralph Hodgson),
  3. University of Manchester (AC rep: Ian Horrocks), and
  4. webMethods, Inc. (AC rep: Prasad Yendluri)

hereby submit to the Consortium the following specification, comprising the following documents attached hereto:

  1. OWL 1.1 Web Ontology Language Overview
  2. OWL 1.1 Web Ontology Language Structural Specification and Functional-Style Syntax
  3. OWL 1.1 Web Ontology Language XML Syntax
  4. OWL 1.1 Web Ontology Language Model-Theoretic Semantics
  5. OWL 1.1 Web Ontology Language Mapping to RDF Graphs
  6. OWL 1.1 Web Ontology Language Tractable Fragments

which collectively are referred to as "the submission". We request the submission be known as the OWL1-1 submission.


OWL 1.1 extends the W3C OWL Web Ontology Language with a small but useful set of features that have been requested by users, for which effective reasoning algorithms are now available, and that OWL tool developers are willing to support. The new features include extra syntactic sugar, addition property and qualified cardinality constructors, extended datatype support, simple metamodelling, and extended annotations.

Change control

The authors expect to continue evolution of OWL 1.1 until such time as a W3C working group is formed. After that time, we would expect future versions to be produced by W3C process.
