Definition

Telos (From the Greek word τέλοζτΘ which means end; the object aimed at in an effort; purpose.) is a knowledge representation language designed especially to support the development of information systems. Telos is based on the premise that information system development is knowledge-intensive and that the main design goal of any language intended for the task should be to formally represent the relevant knowledge. Telos is founded on core concepts from data modeling and knowledge representation, and shares ideas with semantic networks and frame systems, semantic and object-oriented data models, logic programming and deductive databases. The main features of Telos include: a structurally object-oriented framework which supports aggregation, generalization and classification; a novel treatment of attributes as first class citizens in the language; a powerful way of defining meta-classes; an explicit representation of time; and facilities for specifying integrity constraints...
