Development of a Mapping-Layer between document oriented and graph oriented databases

Due to their performance, flexibility and ease of use are document oriented databases like MongoDB becoming more and more important. This simplicity is achieved through limited query capabilities. For example joins are only feasible to a limited extend. For this reason the goal of this theses is to combine the advantages of a document oriented database with the advantages of a graph based database system. Therefore mappings between the two data models RDF and JSON on the one hand and the query languages on the other hand have to be developed. These mappings will be integrated into the rdf-database spiderstore and finally evaluated against the document oriented database MongoDB.
