Hello Ashok, Asio Semantic Bridge for Relational Databases(SBRD) maps/rewrites SPARQL queries to SQL and converts SQL result set to RDF. The approach we have taken for semantically merging data from one or more RDB(s) is to keep data source ontology(or ontologies) separate from the domain ontology and use SWRL mapping rules for mapping data from RDB(s) to the domain ontology. My colleagues @BBN have published a paper for OWLED2008DC that might be of interest to us. The paper is "Use of OWL and SWRL for Semantic Relational Database Translation" and can be downloaded from [3]. Regards Prakash [1] Asio http://asio.bbn.com/ [2] Semantic Bridge for Relational Databases (SBRD) http://asio.bbn.com/sbrd.html [3] http://www.webont.org/owled/2008dc/papers.html >Do any of you know about or have been involved in work that maps SPARQL >queries to SQL? >I'm assuming a Relational database that has been mapped virtually to >RDF. SPARQL Queries >on the RDF representation would need to be translated to SQL queries on >the underlying Relational database. -- All the best, Ashok
