Interface ClassificationScheme

  • All Superinterfaces:
    ExtensibleObject, RegistryEntry, RegistryObject, Versionable 

    public interface ClassificationScheme
extends RegistryEntry
    A ClassificationScheme instance represents a taxonomy that may be used to classify or categorize RegistryObject instances. A very common example of a classification scheme in science is the Classification of living things where living things are categorized in under a tree like structure. Another example is the Dewey Decimal system used in libraries to categorize books and other publications. A common example in eBusiness is that of North American Industry Classification System (NAICS), which is a classification scheme used to classify businesses and services by the industry to which they belong.

    Figure 1 shows how a ClassificationScheme is used by a Classification to classify a RegistryObject.

    • Field Detail

      • VALUE_TYPE_UNIQUE

        static final int VALUE_TYPE_UNIQUE
        Each taxonomy value in ClassificationScheme is unique.
        See Also:
        Constant Field Values

      • VALUE_TYPE_EMBEDDED_PATH

        static final int VALUE_TYPE_EMBEDDED_PATH
        Each taxonomy value in ClassificationScheme embeds the full path from scheme to that Concept. This also implies that each taxonomy value is unique.
        See Also:
        Constant Field Values

      • VALUE_TYPE_NON_UNIQUE

        static final int VALUE_TYPE_NON_UNIQUE
        Taxonomy values in ClassificationScheme may be repeated within the same scheme. However, two Concepts that have the same parent cannot have the same value.

        Constant Field Values
