Interface OntVocabulary

All Known Implementing Classes:
OntVocabulary.Impls.BaseImpl
public interface OntVocabulary
An Ontology Vocabulary. This is a generic interface that simply maps an uri-key to a Set of RDF Resources or RDF Properties, that are defined in vocabulary schemas and represent some family determined by that key. A schema is a java class containing public static final constants. Schemas are usually located inside the packages org.apache.jena.vocabulary and org.apache.jena.vocabulary. There are two kinds of property/resources described by this vocabulary: system and builtin. A system resource/property is simply a URI defined in any scheme. A builtin resource/property is a URI with a known type that does not require explicit declaration. Note that all methods of this interface return unmodifiable Sets.

    • get

      Set<? extends org.apache.jena.rdf.model.Resource> get(String key)
      Answers a Set of system/builtin Resources for the specified URI-key. A URI-key - is a schema URI that determines a family of desired resources. For example, to get all resources a key rdfs:Resource should be used, because it is a supertype of everything.
      Parameters:
      key - String, not null
      Returns:
      a Set of Resources (possibly empty)

    • get

      default <X extends org.apache.jena.rdf.model.Resource> Set<X> get(org.apache.jena.rdf.model.Resource uri)
      Answers a Set of system/builtin Resources for the specified URI-key.
      Type Parameters:
      X - either Resource or Property
      Parameters:
      uri - a URI-Resource, not null
      Returns:
      a Set of Xs, not null but possibly empty
