Summary

This standard provides a globally harmonized (ISO/CEN/HL7) set of representations for data used in the presentation and communication of health care information. This standardized set will be an internationally agreed upon, proper sub-set of data types currently adopted by national and trans-national health care standards development organizations. This document provides a UML and XML implementation of the datatypes, and is in effect Release 2 of the XML ITS datatypes. This document is shared and jointly balloted between HL7, CEN, and ISO.

Description

The communication of health information about individuals requires the accurate identification of specific entities and concepts, as well as the expression of complete, frequently complex semantic phrases. Experience has shown that representation of such data requires that a rich set of data types be built upon the primitive types normally specified for computer software. The set to be specified in this standard will provide the structures necessary to meet the basic requirements of health care information communication.

Benefits

The market for and the supply of healthcare software systems is global. There is an increasing demand to be able to communicate health care data between jurisdictions. Following requests from national health informatics programmes, the vendor community and, also, extensive discussion of previous ISO, HL7 and CEN work on data types, an advanced draft of a new International Standard has now been prepared. This standard will promote a common representation that meets these needs and is being advanced as common draft standard in all three communities. 1. updated datatypes for new requirements from HL7 2. simplified technical implementation path as a result of user feedback 3. shared content between HL7, CEN, and ISO.

Summary

The Abstract Data Types specification includes a Unified Modeling Language (UML) diagram that presents the semantic declarations of these data types in a standard UML fashion.

This UML ITS implements the semantics of the Abstract Data Types specification using UML in such a way that HL7 data types are mapped into the core UML and OCL kernel data types where such mappings are appropriate. In addition, this representation uses only established object-orientated formalisms. Since this specification shows how to implement the HL7 data types using the UML core data types and methodology, this specification is an ITS for the data types in UML.

Description

The desired outcomes from this specification include:

• A formally correct UML declaration of the HL7 Data Types
• Enable the use of Computer-Aided Software Engineering (CASE) tools for model validation, code generation, instance validation, etc
• Enable these same outcomes for downstream HL7 UML artifacts such as the RIM and message structures.
