Class DefaultKeywordClass

  • All Implemented Interfaces:
    Serializable, Emptiable, Lenient­Comparable, Identified­Object

    @TitleProperty(name="className")
    public class DefaultKeywordClass
    extends ISOMetadata
    Specification of a class to categorize keywords in a domain-specific vocabulary that has a binding to a formal ontology. The following properties are mandatory in a well-formed metadata according ISO 19115:
    MD_Keyword­Class   ├─class­Name……………………… Character string to label the keyword category in natural language.   └─ontology………………………… Reference that binds the keyword class to a formal conceptualization of a knowledge domain.       ├─title……………………… Name by which the cited resource is known.       └─date………………………… Reference date for the cited resource.
    Note on International Standard versions
    This class is derived from a new type defined in the ISO 19115 international standard published in 2014, while GeoAPI 3.0 is based on the version published in 2003. Consequently this implementation class does not yet implement a GeoAPI interface, but is expected to do so after the next GeoAPI releases. When the interface will become available, all references to this implementation class in Apache SIS will be replaced be references to the Keyword­Class interface.

    Limitations:

    • Instances of this class are not synchronized for multi-threading. Synchronization, if needed, is caller's responsibility.
    • Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS. For long term storage, use XML instead.

    • Constructor Detail

      • DefaultKeywordClass

        public DefaultKeywordClass()
        Constructs an initially empty keyword class.
      • DefaultKeywordClass

        public DefaultKeywordClass​(CharSequence className,
                                   Citation ontology)
        Creates keyword class initialized to the given key name and ontology.
        Parameters:
        class­Name - a character string to label the keyword category in natural language.
        ontology - reference that binds the keyword class to a formal conceptualization of a knowledge domain.
      • DefaultKeywordClass

        public DefaultKeywordClass​(DefaultKeywordClass object)
        Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, since the other metadata contained in the given object are not recursively copied.
        Parameters:
        object - the metadata to copy values from, or null if none.

      • getClassName

        public InternationalString getClassName()
        Returns a label for the keyword category in natural language.
        Returns:
        the keyword category in natural language.
      • setClassName

        public void setClassName​(InternationalString newValue)
        Sets a label for the keyword category in natural language.
        Parameters:
        new­Value - the new keyword category in natural language.
      • getConceptIdentifier

        public URI getConceptIdentifier()
        Returns the URI of concept in the ontology specified by the ontology citation.
        Returns:
        URI of concept in the ontology, or null if none.
      • setConceptIdentifier

        public void setConceptIdentifier​(URI newValue)
        Sets the URI of concept in the ontology specified by the ontology citation.
        Parameters:
        new­Value - the new URI of concept in the ontology.
      • getOntology

        public Citation getOntology()
        Returns a reference that binds the keyword class to a formal conceptualization of a knowledge domain.
        Returns:
        a reference that binds the keyword class to a formal conceptualization.
      • setOntology

        public void setOntology​(Citation newValue)
        Sets a reference that binds the keyword class to a formal conceptualization of a knowledge domain.
        Parameters:
        new­Value - the new reference that binds the keyword class to a formal conceptualization.
