Rational software architect: a tool for domain-specific modeling

Rational Software Architect (RSA), the latest generation Rational® modeling tool, is based on Eclipse™ Modeling Framework (EMF) technology. RSA offers all the important features of the previous generation of Rational modeling tools, while supporting a much wider range of model formats. RSA diagrams can be used in editing and displaying models derived from any EMF-based metamodel. The combination of RSA and EMF provides a powerful capability for integrating domain-specific languages (DSLs) with UML® in a single toolset. This paper describes how RSA and EMF provide these capabilities and explores some of the ways that IBM is currently exploiting them.
