Description

The goal of this internship is to design and develop a domain speci-fic language for the composition of services in the C osyV erif (http://www.cosyverif.org/) [AHHH+ 13] veri-cation platform.

C osyV erif includes tools, shown as services, developed by researchers of di-fferent laboratories. It handles several formalisms, such as automata and Petri nets. In addition it allows to specify new formalisms to combine existing ones in a new formalism.

Currently, each tool - or service - takes inputs from the user, does its job and then returns a result to the user. We would like to promote the cooperation between tools. This cooperation has several di-erent types : • a tool can take as input the result of another one, • several tools can work in parallel, the result being given by the fastest tool, • a tool can be used as a fallback when another one cannot answer, • ...

Of course, the composition must take care of the type of exchanged data. The types are not only primitive, but also covers a hierarchy of formalisms (with subtyping).

Student Capabilities : The student should have some experience with metamodeling.
