HL7 Version 2 Conformance Methodology Release 1

This standard explains the procedures and processes for constraining HL7 Version 2 message specifications, encompassing both message profiles and implementation guides that contain message profiles. A message profile provides a precise and unambiguous specification of a single message definition. An implementation guide provides a broader context in which, typically, a set of message profiles is used to satisfy one or more use cases. The base HL7 Version 2 standard is a framework that contains numerous message events, and for each event it provides an initial message template (starting point) that is intended to be constrained for a specific use and context.
