My name is Vishal Dave and I am working on one project which requires combination of Spatial database and ontology knowledge base. For spatial database I am using postgreSQL database. I am going to use RESTful web service to fetch data. Can you describe how I can fetch data from postgreSQL database and RDF file by executing one query ? I mean is there any way to convert postgreSQL database into RDF format ? Or is there any common format through which I can access the data from these both at a time ?
