Abstract: The task of WP6 is to evaluate the CONNECT technologies under realistic situations. To achieve this goal, WP6 concentrated its 3rd year effort on the development of a main scenario in the context of GMES, which requires the connection of highly heterogeneous and independently built systems provided by the industry partners. The resulting scenario allows the consortium to assess the validity of CONNECT claims and to investigate the exploitation of CONNECT technologies in the context of the integration of real systems. Another objective of this report is to provide a first assessment of CONNECT solutions against the project's objectives stated in the DoW. The proposed assessment spans: (i) the project's overall objective of enabling on-the-fly interoperability among heterogeneous networked systems as well as (ii) the project's specific objectives related to the foundations and associated enablers to be elaborated for learning and reasoning about the interaction behaviours of networked systems and for synthesizing mediators so as to make systems interoperate.
