Abstract: The identity management systems are a huge domain for users and application data management. As a voted system to work on, the federated system proved on it legibility to solve a several numbers of digital identity issues. However, the problem of interoperability between federations, still the researcher first issue to achieve the objective of creating a federation of federations which is a large meta-system composed of several different federation systems. The technical interoperability approach solved a part of the above-mentioned issue. However, they still many problems in the communication process between federated systems. In this work, the researcher target the semantic interoperability as a solution to solve the exchange of heterogeneous attribute issues. Due to the increasing number of the federated system’s users’, there is a significant requirement of managing the users’ attributes coming from different federations. Therefore the researcher proposed a semantic layer to enhance the technical previous approach with the objective to guarantee the exchange of attribute which has the same semantic signification but a different representation, all that based on an intermediate ontology which guarantees the semantic mapping between different federations. This approach is applied to the academic domain.
