HL73.0消息模型(information model)问题

zouyanbiao

HL3.0中定义了三种类型的消息模型RIM/D-MIM/R-MIM,我研究了HL73.0标准一段时间，也仅仅明白D-MIM是RIM的子集，同时R-MIM是D-MIM的子集。具体到，比如说我要用HL73.0为一个人体生理参数的检测系统（客户端带有监护仪，可检测患者血压、脉搏、心率、心电图等生理参数，检测完成后要将这些数据送到服务器端数据库）建模，应该采用何种模式？
刚刚开始研究，请不吝赐教！！！
非常感谢！！！

这位老兄对HL7 v3的学习在国内应该算已经比较深入啦，估计这个问题的要自己摸索，或者问问国外的专家了

能否具体讲解一下这三种模式？为什么要定义消息模式，适用场合是什么？和具体消息的格式有什么关系？我刚刚开始学，还摸不到门路。

你说的检测系统是能否具体点说明，如果是比较通用的，例如在2.4版中定义过的，好象用RIM就可以，如果没有，需要你自己创建新的消息，用R-MIM和D-MIM中的哪一个来构件我也不明白。
大家来讨论一下好吗？

你误解了RIM/D-MIM/R-MIM的含义，RIM是对整个医学环境中信息模型的抽象，D-MIM则是对某一个业务环境中信息模型的抽象，它实际上相当于RIM在这个领域中的实例。
而在进行Hl7 V3的消息构造和解析时，一般都会使用RIM来进行处理。
如果你实现的系统要将来能够支持Hl7 V3的消息，你可以按照RIM进行建模，这样在你将来进行Hl7 V3的消息处理就比较简单。也可以完全独立建模，只要能在你的数据模型和RIM间Mapping就行。

对不起，我是没弄明白，看了introduction也不大明白，
那么D-MIM/R-MIM的关系呢？
谢谢

1. Domain Information Model (DIM)
The DIM is used to express the information content for the work of a specific Technical Committee, Special Interest Group, or project.  The model is developed or refined by the committee during the information modeling stage of message development.  The Reference Information Model (RIM) is the starting point for the DIM.  The committee uses the DIM to capture potential additions and changes to the RIM, which it may later submit as RIM change proposals for harmonization.
2. Reference Information Model (RIM)
The RIM is used to express the information content for the collective work of the HL7 Working Group.  The RIM is a coherent, shared information model that is the source for the data content of all HL7 messages.  The RIM is maintained by a collaborative, consensus building process involving all Technical Committees and Special Interest Groups.  Through a process known as model harmonization, DIM model content submitted as RIM change proposals is debated, enhanced, and reconciled by Technical Committee representatives and applied to the RIM.
3. Message Information Model (MIM)
The MIM is used to express the information content for one or more related messages.  A Technical Committee extracts this model from the RIM during the Message Design stage of the message development process.  The MIM starts out as a proper subset of the RIM.  The Technical Committee may add message specific information constraints.  No new information content is added at this point in the message development process and information constraints added at this point are not allowed to relax constraints specified in the RIM.
