Athena
Athena is the OHDSI (Observational Health Data Sciences and Informatics) standardized vocabulary repository that provides access to standardized terminologies and vocabularies for observational healthcare data. It includes SNOMED CT, RxNorm, LOINC, ICD codes, and many other standard vocabularies, along with mappings between them. Athena enables the transformation of healthcare data into the OMOP Common Data Model format for federated research across multiple healthcare systems. Access to vocabulary selection and download workflows is mediated through the Athena web application rather than stable public download URLs.
