Overview: HL7 V2 ADT Message Specifications

The ITK HL7 V2 ADT messages are a constraint on the HL7 V2 A3 profile from HL7 UK. The A3 profile is predominantly based on the HL7 V2 international version 2.4 standard with some pre-adoption of the HL7 V2 international verison 2.5 standard.

This subpack is designed to be used in conjunction with ITK Core version 1.0

This pack contains following artefacts -

- Message structure in HTML format
- Message profile specifications in HTML format.
- Message schema to be used for on-the-wire validation.
- Message schema with field and vocabulary bindings (for conformance purpose).
- Message examples in pipe-and-hat encoding and XML encoding.
- Vocabularies used in HL7 v2 ADT specifications in XML and HTML format.
- Tool to convert pipe-and-hat encoded message instances to XML encoded and vice-versa.
