OHDSI logo OMOP Standardized Vocabularies

The Standardized Vocabularies contain all of the code sets, terminologies, vocabularies, nomenclatures, lexicons, thesauri, ontologies, taxonomies, classifications, abstractions, and other such data that are needed for:

  • Generation of the transformed (i.e., standardized) data from the raw source dataset into the OMOP CDM,
  • Searching, querying and extraction of the transformed data, and browsing and navigating the hierarchies of classes and abstractions inherent in the transformed data, and
  • Interpreting the meanings of the data.

Standardized Vocabularies are an integral part of the OMOP CDM. This asset is available for free to anyone and can be downloaded from the download page. Unless otherwise specified for a few commercial vocabularies, vocabularies and their concepts are Open Source. Please see Apache License V2.0 for details.
