3a. Project Scope
To describe a flexible self-describing standard logical model for format and distribution of terminology knowledge bases. The logical model will include the ability to represent structures/collections like value sets, refsets, etc.
The resulting logical model is aimed to standardize representation of machine-processable semantics, consistent representation of language and dialect, and change over time.
References and previous standards that will be considered include:
- The Data Management Requirement re: reference data (DMBOK 2019)
- Existing ISO Standards including https://www.iso.org/standard/32881.html, https://www.iso.org/standard/61979.html
- Existing HL7 standards including CTS2, MIF and FHIR
Specifically, the scope includes 1) outlining how the standardized terminology knowledge base can support FHIR resource generation, perhaps closing gaps that are currently covered as extensions 2) a gap analysis of CTS2 logical model, including an evaluation of why it may be considered a unsuccessful attempt to provide a single logical model, so that those pitfalls may be avoided with this attempt
3b. Project Need
This project is intended to create a logical model and distribution format to represent represent HL7 Codesets, SNOMED, LOINC, RxNorm, and other clinical terminologies. This model is needed to represent machine-processable semantics for standard terminology and local content/concepts. More specifically, the guidance is needed to describe how a "sanctioned standard terminology knowledge base" can allow integration of standard content (e.g., currently LOINC can’t be modeled in a SCT model or published in SCT format).
