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 - Jim Hendler DAML Program Manager --------- Preliminary release - DAML-ONT 0.5 The documents in this collection reflect the contributions of a large number of people and projects.
