A Meta-Model for Textual Use Case Description.

Abstract

A Use Case is a specification of interactions involving a system and external actors of that system. The capability for use case modeling has been integrated to the Unified Modeling Language (UML) since its inception. However, use cases are only defined at an abstract level, as the UML Specification does not discuss use case description in text form. In this paper, we propose an abstract syntax for textual use case description as a meta-model extension of the UML Specification. This meta-model is based on elements commonly found in use case templates. The meta-model also includes OCL constraints for ensuring consistency with the UML specification.
