"Interoperability of technical enterprise applications " thesis

This thesis was initiated at in 2007 after the end of the ATHENA program, and was successfully defended the 27th of November, 2009, in front of an international jury mixing both academic research and industry. As a result Nicolas Figay was unanimously congratulated and awarded as doctor in computer science from the University Claude Bernard Lyon1.


Within the current economic context, enterprises are facing new interoperability issues due to increasing needs of eBusiness Collaboration within the emerging digital ecosystems they belong to. They also need to be able to keep in pace with their heterogeneous internal legacy systems. In addition, they should not have to modify their infrastructure or applications for fast and short collaboration implying information and knowledge interchange with new partners of their ecosystem. In one hand, current solutions are less and less adapted to face increasing needs and complexity in term of interoperability. In the other hand, legacy interoperability standards and frameworks can’t be replaced as it can be imagined to propose new disruptive approach and technologies.

The research work undertaken for the thesis “Interoperability of Technical Enterprise Applications” consists in proposing an innovative approach allowing a given and mature ecosystem to build an enterprise application interoperability framework based on simultaneous and coherent usage of eBusiness standards used by a given ecosystem, combining usage of the different relevant frameworks supporting these standards. The goal is achievement of "pragmatic" interoperability. Proposed innovative approach takes advantage of simultaneous usage of Model Driven Engineering, Enterprise Modeling, Ontology and Service Oriented Architecture. It promotes systematic usage of commodities on the WEB based on open and governed standards. Doing so, semantic preservation between ecosystem’s standards, application engineering artifacts and communication infrastructures is crucial. To support semantic preservation within the context of the innovative proposed approach, the concept of “extended hypermodel” is developed and demonstrated within the context of Product Lifecycle Management within networked organizations.
