Sažetak

Traditional mediators are usually developed as monolithic systems which envelope the data source's semantics as well as its location. Furthermore, their architecture based on wrappers involves a high degree of coupling among the mediators' components. This coupling does not allow sharing services with other organizations or the dynamic integration of new data sources. Therefore, wrappers must be re-designed and manually added for each mediation system. We propose an architecture based on P2P philosophy for semantic mediation in which the sources ' query capabilities are published as web services. These services can be registered in one or more resource directories (Semantic Directories), which are the core of this architecture because they provide the needed flexibility and scalability for dynamic integration.
