Frameworks Generate Domain-Specific Languages: A Case Study in the Multimedia Domain

摘要

We present an approach to software framework development that includes the generation of domain-specific languages (DSLs) and pattern languages as goals for the process. Our model is made of three workflowsȁ4;framework, metamodel, and patternsȁ4;and three phasesȁ4;inception, construction, and formalization. The main conclusion is that when developing a framework, we can produce with minimal overheadȁ4;almost as a side effectȁ4;a metamodel with an associated DSL and a pattern language. Both outputs will not only help the framework evolve in the right direction, but will also be valuable in themselves. In order to illustrate these ideas, we present a case study in the multimedia domain. For several years, we have been developing a multimedia framework. The process has produced a full-fledged domain-specific metamodel for the multimedia domain, with an associated DSL and a pattern language.
