Supporting OCL as Part of a Family of Languages

With the continued interest in Model Driven techniques for software

development more and more uses are found for query or expression languages

that navigate and manipulate object-oriented models. The Object Constraint

Language is one of the most frequently used languages; however, its original

intended use as a constraint expression language has been succeeded by its

frequently proposed use as a basis for a more general model query language,

model transformation language and potential action language. We see a future

where OCL forms a basis for a family of languages related in particular to

Model Driven Development techniques; as a consequence we require an

appropriate tool suite to aid in the development of such language families. This

paper proposes some important aspects of such a tool suit.
