INTERFACE BETWEEN SPARQL SYSTEMS AND A NON-SPARQL SYSTEM

摘要

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.

1. A computing system for executing SPARQL queries generated by SPARQL systems, the SPARQL systems having a SPARQL front end and a SPARQL query engine, the computing system comprising:
an RDF data store; a non-SPARQL query engine that
receives commands in a format specific to the non-SPARQL query engine, the commands for accessing the RDF data store;performs instructions for accessing the RDF data store in accordance with the commands; andprovides results of accessing the RDF data store; and a translated SPARQL processor that
receives from the SPARQL query engine a translated SPARQL query representation of a SPARQL query;process the translated SPARQL representation query to generate commands in a format specific to the non-SPARQL query engine, the commands for directing the non-SPARQL query engine to access the RDF data store for execution of the SPARQL query;sends the generated commands to the non-SPARQL query engine;receives results of the generated commands; andprovides the results to the SPARQL front end.
