javax.xml.registry.infomodel Interface Concept

All Superinterfaces:
ExtensibleObject, RegistryObject
public interface Concept
extends RegistryObject

Implements: RegistryObject

Concept 接口用于表示分类元素及其彼此之间的结构关系，以便描述内部分类。Concept 实例用于定义树结构，其中树根是 ClassificationScheme 实例，树中的每个节点是 Concept 实例。可以定义两个 Concept 相等。

图 1 展示了如何使用 Concept 实例表示分类元素及其彼此之间的结构关系，以便描述内部分类。

英文文档：

The Concept interface is used to represent taxonomy elements and their structural relationship with each other in order to describe an internal taxonomy. Concept instances are used to define tree structures where the root of the tree is a ClassificationScheme instance and each node in the tree is a Concept instance. Two Concepts may be defined as being equivalent.

Figure 1 shows how Concept instances are used to represent taxonomy elements and their structural relationship with each other in order to describe an internal taxonomy.
