Class RdfOwlOutputProcessor

java.lang.Object
  com.raritantechnologies.concept.rdf_owl.RdfOwlOutputProcessor

All Implemented Interfaces:

IGatewayOutputProcessor

public class RdfOwlOutputProcessor

extends java.lang.Object

implements IGatewayOutputProcessor

Uses Jena API to convert IResultSet into Resource Description Framework (RDF) fact statements (Subject-relationship-Object 'triples') that can be used by a Ontology-based query processor. Maps RDF "triples" subject-predicate-object into a repository based on an RDF or OWL schema and an RDF - SearchSource mapping. Ensures that the data corresponds to the RDF ontology.

XML Configuration Template:

   <GatewayOutputProcessor class="com.raritantechnologies.concept.RDF.RDFOutputProcessor"
                              subjectField="[ result field with subject name ]"
                              defaultSubject="[ default subject (use if no field for subject) ]"
                              valueField="[ result field with the fact 'Object' value ]"
                              defaultRelationship="[ the relationship between subject and 'Object' ]" >

     <!-- Optional table defining mapping of result fields to subject/object "relationships" -->
     <FieldRelationships>
       <Field ID="[ result field with 'Object' value ]" relationship="[ name of fact relationship ]" />
       <!-- etc. . . -->
     </FieldRelationships>

   </GatewayOutputProcessor>
