Mapping - the resources
Post coordination resources
Enclosed are two spreadsheets of the mapping of HPO (Human Phenotype Ontology) to SNOMED. The first is a list of the complete mappings of 17960 HPO terms, including direct maps and expressions, the second contains just the expressions. These expressions have been authored using the following resources and validated against the April 2024 Release of SNOMED International;
- Machine Readable Concept Model
- https://browser.ihtsdotools.org/mrcm/?branch=MAIN%2F2020-07-31
- Postco-ordination demonstrator - expression validation (classification)
- Ihtsdo.github.io/ii-postcoordination/
- Postcoordination Implementation Demo (ihtsdo.github.io)
- Practical Guide to Post-coordination
- https://snomed.org/postcoordination
- SNOMED International browser
