    Description
    static Map<String,​Set<String>>
    getAnnotationLiteralsForEntity​(org.semanticweb.owlapi.model.OWLOntology ontology, org.semanticweb.owlapi.model.OWLEntity entity, org.semanticweb.owlapi.model.OWLAnnotationProperty annotationProperty)
    Return a Map that contains all known values for a given annotation property for a given OWL entity, grouped by language tags.
    static Set<String>
    getAnnotationLiteralsForEntity​(org.semanticweb.owlapi.model.OWLOntology ontology, org.semanticweb.owlapi.model.OWLEntity entity, org.semanticweb.owlapi.model.OWLAnnotationProperty annotationProperty, List<String> langs)
    Extract literal values for an annotation property applied to an OWL entity in an ontology for a particular set of languages.
    static org.semanticweb.owlapi.model.OWLAnnotationProperty
    getLabelProperty​(org.semanticweb.owlapi.model.OWLOntology ontology)
    Returns OWL property rdfs:label, using a cache so we don't need to load the property using the data property.
    static Set<String>
    getLabelsInEnglish​(org.semanticweb.owlapi.model.OWLNamedIndividual individual, org.semanticweb.owlapi.model.OWLOntology ontology)
    Return a list of labels for an OWLNamedIndividual in English or (if no such label is known) with no language provided.

    • getLabelProperty

      public static org.semanticweb.owlapi.model.OWLAnnotationProperty getLabelProperty​(org.semanticweb.owlapi.model.OWLOntology ontology)
      Returns OWL property rdfs:label, using a cache so we don't need to load the property using the data property.
      Parameters:
      ontology - The ontology whose OWLAnnotationProperty we want.
      Returns:
      The OWLAnnotationProperty of rdfs:label.

    • getLabelsInEnglish

      public static Set<String> getLabelsInEnglish​(org.semanticweb.owlapi.model.OWLNamedIndividual individual, org.semanticweb.owlapi.model.OWLOntology ontology)
      Return a list of labels for an OWLNamedIndividual in English or (if no such label is known) with no language provided.
      Parameters:
      individual - The OWLNamedIndividual whose labels need to be retrieved.
      ontology - The ontology within which this individual is defined.
      Returns:
      A list of labels as Java Strings.

    • getAnnotationLiteralsForEntity

      public static Set<String> getAnnotationLiteralsForEntity​(org.semanticweb.owlapi.model.OWLOntology ontology, org.semanticweb.owlapi.model.OWLEntity entity, org.semanticweb.owlapi.model.OWLAnnotationProperty annotationProperty, List<String> langs)
      Extract literal values for an annotation property applied to an OWL entity in an ontology for a particular set of languages. If no literals are found for any of the specified languages, we will return literals that don't have an explicit language tag (i.e. an xsd:string instead of an rdfs:langString). If no such literals are known, we return an empty set.
      Parameters:
      ontology - The ontology containing the entity and the annotation property to extract
      entity - The entity to extract annotations for
      annotationProperty - The annotation property to extract (usually rdfs:label)
      langs - Languages to extract annotation literals for, in order of importance
      Returns:
      Set of annotation property values for the first matched language, or those associated with no languages

    • getAnnotationLiteralsForEntity

      public static Map<String,​Set<String>> getAnnotationLiteralsForEntity​(org.semanticweb.owlapi.model.OWLOntology ontology, org.semanticweb.owlapi.model.OWLEntity entity, org.semanticweb.owlapi.model.OWLAnnotationProperty annotationProperty)
      Return a Map that contains all known values for a given annotation property for a given OWL entity, grouped by language tags. The special language tag "" is used as the key for literals without an explicit language tag.
      Parameters:
      ontology - The ontology containing the OWL entity and the annotation property to query
      entity - The OWL entity to query
      annotationProperty - The annotation property to query
      Returns:
      A Map of annotation values organized into Sets by language.
