We consider a parallel Algol-like language, combining procedures with shared-variable parallelism. Procedures permit encapsulation of common parallel programming idioms. Local variables provide a way to restrict interference between parallel commands. The combination of local variables, procedures, and parallelism supports a form of concurrent object-oriented programming. We provide a denotatio...

Let S be some type system. A typing in S for a typable term M is the collection of all of the information other than M which appears in the final judgement of a proof derivation showing that M is typable. For example, suppose there is a derivation in S ending with the judgement A ` M : τ meaning that M has result type τ when assuming the types of free variables are given by A. Then (A, τ ) is a...

As the UML attempts to make the transition from a single, albeit extensible, language to a framework for a family of languages, the nature and form of the underlying meta-modeling architecture will assume growing importance. It is generally recognized that without a simple, clean and intuitive theory of how metamodel levels are created and related to one another, the UML 2.0 vision of a coheren...
