its logical model

Others are derived through the "shredding" of a key-type service description document into its logical model.

其他属性是通过将关键类型的服务描述文档“分解”为其逻辑模型来派生的。

Each system has its own proprietary semantic meaning, but is mapped to a logical data model which can be instantiated as a physical federated model or a canonical message model.

每个系统都有其专有的语义，但是被映射到一个逻辑数据模型，可以将此模型实例化为一个物理联合模型或规范消息模型。

This section shows you how to do this using a physical model and its objects. A similar approach can be used for logical models as well.

本节展示如何使用一个物理模型及其对象来实现这个目标——对于逻辑模型也可以使用类似的方法。
