摘要
Standardization experts in object modelling are having difficulties with defining the concept of role; for example, they are not sure of whether role is a type or an instance concept. This issue is a source of confusion in the UML standard, and prevents ISO experts to reach consensus and finalize a language for ODP enterprise modelling. In this paper we make an in-depth analysis of the problem, find its likely causes, and come zip with a proposal for a new ODP definition of role, as well as with definitions of related concepts. Our findings and our definitions provide a basis for reconciling the positions that people have about the concept of role.
