3.2.2 RDFDB Use

The RDFDB service is already available in the distribution and one could use it either by generating a JMS client or through the OpenRDF Sesame API.

Using the RDFDB by Generating a JMS Client

Generating a Client

Using your shell, navigate to the bin directory of the deployed platform and invoke the following commands:

mkproxy -proxy com.ontotext.platform.qsg.ServiceClass $PATH_TO_EXAMPLES/target/classes/

mkproxy -client com.ontotext.platform.qsg.ServiceClass $PATH_TO_EXAMPLES/target/classes/

Both commands dump output to sysout. Get the code, clean it as appropriate and put it in your project's source code. Build the project and the client is located in your project's target directory. The client implements the interface of the service.

Generating RDF-DB Clients

In order to use RDF-DB clients, the following services must be generated:

com.ontotext.rdfdb.ordi.OrdiService

com.ontotext.rdfdb.ordi.RdfStoreService

com.ontotext.rdfdb.ordi.RdfQueryService

Using the RDFDB through the OpenRDF Sesame API

By using the OpenRDF Sesame API one could manage and query the default repository through the Sesame Workbench, or operate over it using the HTTP Repository. The OpenRDF Sesame is integrated in the RDFDB. For more details about how to use it, please see the OpenRDF Sesame User Guide.
