Abstract

Designing object models with concurrency features was a preoccupation of numerous researchers for the past two decades. UML, the standard object-oriented modeling language adopted by the OMG, does not tackle the issues of concurrency in its object model in a systematic way. In this paper we outline the position of the UML object model within the design space of concurrent object models described in [10], discuss the inconsistencies in the UML semantics and finally propose an object model, comprising features from UML and ATOM - a state-of-the-art concurrent object model.
