how to use node js to query a owl ontology file

I have a owl file with a ontology, now I am using php with the RAP library to query this file, but I have to change this and using a node rest service, but I have no idea how to query this file using node. May be some one has something info to reach this.

Thanks...

As far as I know there's no javascript libraries/module to handle OWL ontologies. Lot's of work as been done in Java, you can think of this language to build your application. You can look at the OWL-API or Jena for an open source and free solution.
