The current UML semantics documentation has made a significant step towards providing a precise description of the UML. However, at present the semantic model it proposes only provides a description of the language's syntax and well-formedness rules. This paper describes work currently being undertaken by the precise UML group (pUML), an international group of researchers and practitioners, to address these problems. A formalisation strategy is presented which concentrates on giving a precise denotational semantics to core elements of UML. This is illustrated through the development of precise definitions of two important concepts: generalization and packages. Finally, a viewpoint architecture is proposed as a means of providing improved separation of concerns in the semantics definition.
