SPARQL
The SPARQL Plugin allows a user to SPARQL queries over ontologies loaded into the NTK. It receives an OWL ontology and a query expressed using SPARQL syntax as inputs and outputs the answers in a table. In addition to querying local ontologies, the SPARQL Plugin allows for evaluating queries over a Linked Data substrate, i.e. translates SPARQL queries to Linked Data lookups on the web.
The SPARQL plugin can be applied in the reuse activities, i.e. to find out about already existing ontological resources, and in the evaluation activity to test if specified queries can be answered using the modelled ontology.
