This language was followed by an extension entitled DAML+OIL which included researchers outside of the DARPA program in the design. The 2002 submission of the DAML+OIL language to the World Wide Web Consortium (W3C) captures the work done by DAML contractors and the EU/U.S. ad hoc Joint Committee on Markup Languages. This submission was the starting point for the language (later called OWL) to be developed by W3C's web ontology working group, WebOnt.
