Shared properties（共享属性）¶

A shared property is a property that can be used on multiple object types in your ontology. Shared properties allow for consistent data modeling across object types and centralized management of property metadata. While property metadata is shared across objects, the underlying object data is not.

For example, in Ontology Manager, you may have Employee and Contractor object types that both have the property start date. By creating a start date shared property and using it for both object types, you can model your data using a consistent property and update start date metadata in one place instead of on each object type.

Shared properties can be created directly, or existing properties on object types can be converted into shared properties. Once added to your ontology, shared properties can be used on object types as part of ontologizing your data and edited in a manner similar to regular properties.

共享属性¶

共享属性（shared property）是一种可应用于本体论（ontology）中多个对象类型的属性。共享属性支持跨对象类型实现一致的数据建模，并集中管理属性元数据。虽然属性元数据在对象间共享，但底层对象数据并不共享。

例如，在 Ontology Manager 中，您可能拥有 Employee 和 Contractor 两种对象类型，它们都包含 start date 属性。通过创建 start date 共享属性并将其应用于两种对象类型，您可以使用一致的属性来建模数据，并在一处更新 start date 元数据，而无需在每个对象类型上单独操作。

共享属性可以直接创建，也可以将对象类型上的现有属性转换为共享属性。一旦添加到本体论中，共享属性即可在数据本体化过程中用于对象类型，并像常规属性一样进行编辑。
