The amount of semantic data on the Web has increased exponentially in the last years. One of the main reasons for this is the use of RDB2RDF systems, which generate RDF data from relational databases. Most of the work on these systems has focused on increasing the expressivity of query languages, analyzing their coverage over databases and generating sound, complete and efficient query plans. However, there are still important problems associated to them, especially in terms of robustness and in the handling of data distribution. In this paper we describe how we have integrated one RDB2RDF system (ODEMapster) with OGSA-DAI in order to overcome these problems.
