A method and system for interfacing SPARQL front ends of SPARQL systems to a non-SPARQL system is provided. A translated SPARQL ("tSPARQL") system inputs a translated SPARQL query, generates commands for a non-SPARQL system based on the tSPARQL query, and provides those commands to the non-SPARQL system for executing the SPARQL query corresponding to the tSPARQL query. The tSPARQL system translates the tSPARQL query into commands that are provided to a non-SPARQL query engine for executing the SPARQL query represented by the tSPARQL query. When the tSPARQL system receives results of the commands, it provides the results to the SPARQL front end.
