RDF Store integration

[shinhokang]

two functions and RDF store should be integrated.

getIDOntologies(): GET /ontologies getOntology(): GET /ontologies/{id}

[shinhokang]

I think this can be done without using another database (for the xml)

storing RDF would be another task

for RDF store - check this out. https://jena.apache.org/documentation/tdb/

I implemented the first version of the RDFStore and the correspondent endpoints listed below, three points to take into account:

• The ontologies are generated by hard code (because the transformation is in process).
• Right now the ID is not an Integer, I think that we can use an String as the ID.
• In the folder js there are some simple Node.js example scripts implementing the call to the endpoints
