Abstract

Data Type which consists of an object and an execution submodel. Both are influenced by the context and 4 organization in which their instances are used -- large communities of software developers, users, and managers. Change, complexity, and heterogeneity of representation are ubiquitous in specification management. They must be addressed in the object submodel, e.g., by representations for versioning, configuration, and mapping between different object views. The execution model has to cope not only with the problems of multi-version concurrency control but also with explicit communication and coordination in large development teams, possibly distributed in space and time. The meta data model that supports such a setting could in principle be very loose (e.g., hypertext), or it could require full formalization of the available language concepts, methods, and tools, even of the roles of human developers. Probably, neither extreme should be followed. Simple hypertext structures have ...
