A crucial prerequisite for the deployment and success of peer-to-peer data management applications is the availability of metadata in a way that makes it easy to access and combine data from different sources and domains. In this paper, the authors argue for a unified and distributed infrastructure providing a repository for semantic data by offering location transparency and advanced query services. After discussing the challenges of such an approach, they present their solution which applies extended SPARQL-like query features for dealing with large and possibly heterogeneous data sets.
