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.

VALUE_TYPE_UNIQUE

static final int VALUE_TYPE_UNIQUE

Each taxonomy value in ClassificationScheme is unique.

常量字段

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.

常量字段

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.
