This project investigates distribution in querying on ontology-based data stored in a distributed collection of Semantic Web systems. With the data not being stored in a single repository, but being offered through a network of connected repositories, we come one step closer to a true Web-like platform for information sharing. Obviously, the querying and retrieval of data from that network needs to take the aspect of distribution into account without losing the benefits of the formal grounding for dealing with ontology-based information. The notion of distribution has already been studied in the field of relational databases. However, a number of characteristics of Semantic Web query systems make the reuse of these results less than trivial.
