Vocabulary Tooling Requirements

From HL7Wiki
Jump to navigation Jump to search

Purpose

The scope of this project is to identify software solutions that are able to manage the HL7 Vocabulary (code systems, value sets, concept domains and bindings) in a manner that facilitates HL7’s creation and maintenance of that content.

Project Scope Statement (approved by HL7 TSC, project #947 in Project Insight)

Project Need

HL7 has developed and maintains a vocabulary resource consisting of code systems, concept domains, and value sets, and bindings that are used in the development and use in HL7 artifacts. This content is reviewed and maintained three times a year during HL7 Vocabulary and RIM Harmonization meetings.

The set of tools currently used to maintain the HL7 content is insufficient to manage the complete set of operations needed to support terminology management activities, requiring a number of manual enhancements that are proving increasingly difficult to maintain. As a result, it is often necessary to perform direct database updates, as well as manual file merges. These tooling insufficiencies result in errors and inconsistencies in the vocabulary content over time.

Additionally, there is a requirement to promote the use of standard terminologies from external terminology providers such as the IHTSDO and Regenstrief.

Success Criteria

1. Demonstration of the ability to load the HL7 vocabulary into a running instance of the software.

2. The ability to perform HL7 vocabulary maintenance operations.

3. The ability to represent and build value set based on standard external code systems such as SNOMED CT and LOINC.

4. The ability to export the updated vocabulary in a format that is consistent with the balloted HL7 Value Set Definition specification.

5. Must be able to export the HL7 content to a MIF based representation to meet existing HL7 publishing requirements.
