Editing DARPA Agent Markup Language

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 program focused on the creation of machine-readable representations for the Web. 

One of the Investigators working on the program was [[Tim Berners-Lee]]. Working with the program managers and other participants, Tim helped shape the effort to create technologies and demonstrations for what is now called the [[Semantic Web]], leading in turn to the growth of [[knowledge graph]] technology.

A primary outcome of the DAML program was the DAML language, an  [[user agent|agent]] [[markup language]] based on  [[Resource Description Framework|RDF]].  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 [[European Union|EU]]/[[United States|U.S.]] ad hoc Joint Committee on Agent Markup Languages.  This submission was the starting point for the language (later called [[Web Ontology Language|OWL]]) to be developed by W3C's web ontology [[working group]], WebOnt.

DAML+OIL was a syntax, layered on [[Resource Description Framework|RDF]] and [[XML]], that could be used to describe sets of facts making up an [[ontology (computer science)|ontology]].

DAML+OIL had its roots in three main languages - DAML, as described above,  [[Ontology Inference Layer|OIL]] (Ontology Inference Layer) and  [[Simple HTML Ontology Extensions|SHOE]], an earlier US research project.

A major innovation of the languages was to use RDF and XML for a basis, and to use RDF namespaces to organize and assist with the integration of arbitrarily many different and incompatible ontologies.

Articulation ontologies can link these competing ontologies through codification of analogous subsets in a [[Objectivity (philosophy)|neutral point of view]], as is done in the [[Wikipedia]].

Current ontology research derived in part from DAML is leading toward the expression of ontologies and rules for reasoning and [[action (philosophy)|action]]. 

Much of the work in DAML has now been incorporated into [[RDF Schema]], the [[Web Ontology Language|OWL]] and their successor languages and technologies including [[schema.org]]
