A Framework for Service-Based Query Resolution in eEnvironments

While recent works in P2P data management systems (PDMSs) have focused only on integrating traditional data sources, the access to an increasing number of data sources has been made in the form of data-providing Web services in P2P-based e-collaboration environments. In this paper, we supplement current PDMSs with capability to handle data sources exposed as services. In our solution we model data-providing services as RDF parametrized views. Then we devise an algorithm capable of composing the different data-providing services in order to answer a received query.
