The DARPA Agent Markup Language (DAML) was the name of a US funding program at the US Defense Advanced Research Projects Agency (DARPA) started in 1999 by then-Program Manager James Hendler, and later run by Murray Burke, Mark Greaves and Michael Pagels.
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.
This submission was the starting point for the language (later called OWL) to be developed by W3C's web ontology working group, WebOnt.
DAML+OIL had its roots in three main languages - DAML, as described above, OIL (Ontology Inference Layer) and SHOE, an earlier US research project.
Much of the work in DAML has now been incorporated into RDF Schema, the OWL and their successor languages and technologies including schema.org
