Dynamic component assessment on PvC environments

We aim at automating an integration process for component-based systems. Hence we describe a reference model where its first phase (qualification) is our current work. We intend to compare components data by semantic analysis, i.e. interoperability at a semantic level. Assessment is based on meta-data added to components: their context, assertions, and interface protocol. In a previous work we showed a component interface matching. In this paper we explain the assertions matching, that uses a technique based on abstract syntax trees, which detects similar pieces of code (´clones´). We aim to enhance the procedure by a semantic component treatment using ontologies. Thus the whole assessment procedure is highly improved both on efficacy and reliability.
