? Why HL7 V3?

Compare/contrast HL7 V2 and V3 Messaging

Introduction to HL7 V3 Reference Information Model (RIM)

Understanding the RIM foundational classes

moodCode versus statusCode

Refining the RIM Comparing HL7 V2 and V3

HL7 V2 HL7 V3 Development Model Ad hoc, ground up Formal object-oriented

design methodology Controlled Vocabulary

controlled vocabularies Encoding and

specification (e.g., XML) Optionality Supports localization

through Z segments

The Act class is central to the RIM

Everything revolves around an Act Reading the RIM:

Class Names and Attributes

Class name Attributes Data Type Reading the RIM:

Specializations (Is-A Associations) Attributes of

the Act class Denotes Specialization

Attributes specific to

the Procedure class Attributes specific to

the Observation class RIM Foundation Classes Act: Something that is being done, has been done, can be done, or

is intended or requested to be done

Entity: The ?thing? that participates in the Act

Role: The role that each Entity plays Act statusCode moodCode M moodCode and statusCode are not the same!

moodCode Values: Role Entity Refining the RIM R-MIM Example Summary

In this unit, we learned why V3 was created and explored key

differences between HL7 V2 and V3. We also examined the RIM -the basis for every HL7 V3 product -- and learned that iterative

refinements to the RIM are needed to ?get down? to the details that

an HL7 V3 developer needs to construct a message or document.

Subsequent units will show how to navigate the HL7 V3 standard

and do a deeper dive into one of the most popular HL7 V3 products:

the HL7 V3 Clinical Document Architecture (CDA). References
