周子君教授的HL7普及讲座
[QUOTE]最初由 goonyeah 发表
[B]1、What is the HL7 Reference Information Model?
The RIM is documentation of information from the healthcare domain.
It is used as a common reference for the data content of all HL7 version 3 standards.
The RIM has graphical expression and an accompanying data dictionary.
It is expressed using the Unified Modeling Language notation.
2、What is the Purpose of information Modeling
To aid in understanding information in a particular domain
To communicate the modeler’s understanding of information and allow that understanding to be assessed by others
To aid in reconciling multiple perspectives of information by combining the perspectives into a single specification
To document the design of the data component of an information system so that the design may be evaluated
所以，RIM是用UML语言表达的卫生领域的信息模型，这样就对卫生领域的信息表达有了统一的规范，有了交流的语言，有了评估其实现系统的一个基础！

从描述：

我补充一点：
RIM为一个文档式模型，是具体领域或学科对HL7所含的所有数据单元的解释集合（或词典，还有图形显示），组织成统一的规范，有利于领域或学科间相互理解。
