HL7 Version 3 Standard: XML Implementation Technology Specification - Structures, Release 1.1
The objective of this document is to present an Implementable Technology Specification (ITS) for the encoding rules for HL7 Version 3 messages based on XML (Extensible Markup Language). Several XML encoding methods could serve as a messaging syntax for HL7 V3 messages. This document represents the method that is recommended by HL7, describing the underlying rules and principles. The corresponding data type descriptions necessary for this specification are described in the Data Types XML ITS.
HL7 Version 3 Standard: XML Implementation Technology Specification - Structures, Release 1.1 may also go by the following names or acronyms:
- All implementers of HL7 V3 messaging
- Healthcare Institutions (hospitals, long term care, home care, mental health)
- Healthcare IT Vendors
- National Health Information Exchange Infrastructures
- The implementation of a consistent xml representation of HL7 V3 models provides for wire-format interoperability.
- This work has been made possible by NHS Connecting for Health in the UK
This standard describes how HL7 V3 compliant messages can be expressed using XML. It describes how the definition of the set of valid XML instance documents is derived from a specific HL7 Message Type. It covers ISO levels 5 and 6. Those familiar with V2 might call these the "XML encoding rules" for HL7 Version 3 messages.
This release of the specification introduces an additional extension mechanism allowing extensions to be included in the HL7 namespace. This is described in the section on backwards and forwards compatibility and the section on informal extensions. All other parts of this document remain unchanged from the version 1.0 of this specification.
