In Aerospace industry, the strategy of the main aircraft manufacturers is to outsource more and more sub-assemblies. Thus, level 2 Subcontractors (STR2) develop more complex relationships and high value-added with level 1 sub-contractors (STR1) and their subcontractors (STR3 and following ranks STRN). These relationships, as part of the design and manufacture of composite parts, use different methods of work and are handled through various tools for Design, PLM, Technical Data Management, Production Management.... These tools must be interoperable in a flexible and economical way (fast adaptation to new cooperation ...).
In this context, the Interoperability for Enterprise Software and Applications (IESA) becomes a major issue.
ISTA3 is a research-oriented project, which means it uses research results, which target is to produce prototypes; industrially tested, for which one or several companies showed some interest to obtain a competitive advantage. It is integrating the best of current research in Enterprise Interoperability: EM/ BPM (Enterprise Modeling / Business Process Modeling), Performance Evaluation, MDI (Model-Driven Interoperability), SOA (Service-Oriented Architecture ) Ontology.
