Short for
DARPA Agent Markup Language, DAML is a
semantic markup language that is specifically an extension to
XML and the
Resource Description Framework (
RDF). DAML is used for the U.S. Defense Advanced Research Project Agency (DARPA) and compared to the
XML standard it offers a better capacity to express semantics (describing objects and the relationships between objects), which means a much higher level of interoperability between
Web sites.
