CLASSIC is a data model that encourages the description of objects not only in terms of their relations to other known objects, but in terms of a level of intensional structure as well. The CLASSIC… (More)

We describe Telos, a language intended to support the development of information systems. The design principles for the language are based on the premise that information system development is… (More)
classic is a recently-developed knowledge representation system that follows the paradigm originally set out in the kl-one system: it concentrates on the de nition of structured concepts, their… (More)
