Value Set Definition Standard Project

A New Normative Standard for Value Set Definitions

Overview

[From the PSS] Describe the elements that make up a “Value Set Definition”, and ballot this as a normative HL7 specification, including a demonstration of how this is met in FHIR profiles and HL7 Model Interchange Format (MIF).

The definition of value sets is a required activity in completing the specification of most health information technology artefacts. To date, the approach for doing so has not been consistent within HL7 constructs and elsewhere. Many of the required elements and approaches are embedded in existing HL7 artefacts but not consistently. Currently, an explicit list of all the fields in an HL7 value set definition are surfaced only in the informative balloted MIF, with a general description of them in the normative Core Principles specification. A more accessible and standardized list of these fields is required to facilitate interoperability and sharing of value set definitions across HL7 artefacts and the Health IT community at large.

Success criteria: Publishing of the normative standard, and a demonstration of value set definitions that conform to this published normative specification.
