 Data typeExample data
TBox

"Terminological data"

Defines classes, properties, and relationships in your ontology.

          foaf:Person
   a owl:Class ;
   rdfs:subClassOf owl:Thing ;
   rdfs:label "Person"@en . 
ex:preferredName
   a owl:DatatypeProperty ;
   rdfs:subPropertyOf skos:prefLabel,
                      foaf:name, 
                      rdfs:label ; 
   rdfs:domain foaf:Person ;
   rdfs:label "preferred name"@en .
ABox

"Assertion data"

Enumerates the individual instances of your classes and describes them.

          local:tobyink 
   a foaf:Person ;
   ex:preferredName "Toby Inkster" .
Full

The TBox and the ABox together, treated as a single model.

For example, when you use the RDF tools to remove statements, you want them removed regardless of whether they are found in the TBox or the ABox.

Statement typeMeaningExample data
AssertionsStatements that you explicitly add to the model, either through setup, ingest, or editing. local:tobyink rdfs:type core:FacultyMember .
InferencesStatements that the semantic reasoner adds to the model, by reasoning about the assertions, or about other inferences.
          local:tobyink rdfs:type foaf:Person .
        
          local:tobyink rdfs:type foaf:Agent . 
        
          local:tobyink rdfs:type owl:Thing .
Union

The combination of Assertions and Inferences.

For most purposes, this is the desired model. You want to know what statements are available, without regard to whether they were asserted or inferred.

Notes:

  • The default WebappDaoFactory is the one backed by the unionOntModelSelector. On the request level, this is also known as the "fullWebappDaoFactory". The convenience methodsgetWebappDaoFactory() and setWebappDaoFactory(wdf) support this use.

  • "baseWebappDaoFactory" and "assertionsWebappDaoFactory"  are both previous terms for the WebappDaoFactory backed by the baseOntModelSelector. The convenience methods getBaseWebappDaoFactory() and setBaseWebappDaoFactory(wdf) support this use.

  • Nobody was using the "deductionsWebappDaoFactory", so we got rid of it.
