Capability Management and Discovery in Heterogeneous Environments

Abstract : This thesis addresses the general problem of capability management and capability discovery in heterogeneous environments. We increased a Description Logics language to support capability description, management and discovery. Our main contributions are: 1. the definition of a capability description language ALNr+, based on Description Logic, to support capability management and the associated inference services; 2. The definition of a capability discovery algorithm whose characteristics is, in case of failure when seeking for an "exact" answer, to try to find a composite answer, i.e. to find several individuals whose capabilities complementarily satisfy the capability which is looked for; 3. The design and the partial implementation of a federated mediation system that serves as a platform for the experimental validation of our proposals. A distinguishing feature of this system is that it deals with the situations where capabilities descriptions are distributed among the federated mediators and where they are homogeneous (i.e. they are expressed in the same capability description language) as well as heterogeneous (i.e. they are expressed in different capability description languages).
