Core Properties of V3 Models

Preface

Notes to Readers

This is the first release of this document. It is intended to provide important background information for implementors trying to implement V3 Static Models, whether they are found in Messages, Documents, or Service Payloads.

Introduction and Scope

• a description of the Document at a minimum sufficient for a person unfamiliar with the work to understand the document’s business, scope and relationship with HL7.

• the need for a Specification.

V3 Static Models: Overview

All V3 Static Models are comprised of #RIM classes linked by associations. The classes have attributes which are assigned #datatypes. Some attributes are associated with controlled #vocabularies which provide clearly defined semantic meaning to the static models.

RIM

The RIM defines all the classes that are used in static models. The classes are standard classes in the UML sense, and have associations and attributes as defined in the RIM models.

Datatypes

The datatypes define the types that may be used for the attributes of the RIM classes. The semantics of the types are defined in the abstract datatypes, while the [[ITS datatypes] define an XML implementation of the datatypes
