standard semantics

Unified the information standard on the foundation of Ministry of Education, in view of each semantic conflict type, we used the concept of metadata, described mapping from the unified information standard to semantics definition of various data sources, and defined mapping transformation rule.

在教育部统一信息标准的基础上，针对各种语义冲突类型，引入元数据的概念，描述统一的信息标准到各数据源语义定义的映射，并制定映射转换规则。

例如，UML的标准语义和符号就是用元模型描述的，工具的提供商以一种标准的方法使用元模型来实现UML。
