javax.xml.registry.infomodel Interface ClassificationScheme

All Superinterfaces:
ExtensibleObject, RegistryEntry, RegistryObject, Versionable
public interface ClassificationScheme
extends RegistryEntry

Implements: RegistryEntry

ClassificationScheme 实例表示可用来对 RegistryObject 实例进行分类或归类的分类法。科学中常见的 ClassificationScheme 示例是生物的分类，生物是按树状结构进行归类的。另一个示例是图书馆使用的 Dewey Decimal 系统，它可以对书籍和其他出版物进行归类。电子商务中常见的示例是 North American Industry Classification System (NAICS)，这是一个根据业务和服务所属的行业对它们进行分类的分类方案。

图 1 展示了 Classification 如何使用 ClassificationScheme 对 RegistryObject 进行分类。

英文文档：

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

英文文档：

VALUE_TYPE_UNIQUE 

static final int VALUE_TYPE_UNIQUE
Each taxonomy value in ClassificationScheme is unique.

See Also:
Constant Field Values

英文文档：

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

英文文档：

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.
