As program manager of the "DARPA Agent Markup Language" initiative, I
am pleased to announce the first release of a significant piece of
the DAML language. DAML is an effort to help bring the "semantic
web" into being, focusing on the eventual creation of a web logic
language. It represents joint work between DoD, industry and academia
in both the US and the European Community and we hope it will lead to
the eventual web standard in this area.
This first release is a draft language for the "ontology" core of the
language (roughly corresponding to a frame-based or description logic
starting place) - this allows the definition of classes and
subclasses, their properties, and a set of restrictions thereon. The
language does not yet include any specification of explicit inference
rules, which we hope will follow.
We believe this ontology core will be a useful starting place for
extending the language, and for experiments in a web-based semantic
language that is accessible to a wide audience.
The language is based on RDF (actually RDF Schema) and extends it to
include new concepts.
A group of researchers from MIT's Laboratory for Computer Science had
primary responsibility for developing this language core. This was
then extended by a number of people including representives from the
OIL effort, the SHOE project, the KIF work, and DAML contractors.
Some of the primary contributors are listed below.
Details of the language release and pointers to the above named
projects (and others) can be found at http://www.daml.org
