The system presented in this paper uses Contextual Logic Programming as a computational hub for representing and reasoning over knowledge modeled by web ontologies, integrating the approach with similar mechanisms which we already developed. As a result of its Logic Programming heritage, the system may also recursively interrogate other ontologies or data repositories, providing a semantic integration of multiple sources. The components required to behave as a SPARQL query engine are explained
