Metamodeling for Requirements Reuse

Correct requirements determination is a critical factor in software development as it takes resources and it is an error prone activity which can bring tragic consequences to the rest of the software life cycle. Having stored reusable requirements elements, both qualified and classified, in a repository might contribute to taking advantage of software development resources and to reducing the error probability in requirements specifications. However, the diversity of notations and formats, as well as the existence of different levels of requirements description make requirements reuse difficult. In this paper we present a metamodel to integrate some different types of semiformal diagrams into a requirements reuse approach. The description of reusable elements constitutes the basis for benefiting from diverse representations of requirements in the development of specifications by reusing requirements.
