is an Aggregator.
It is part of the OMOP collection.
Observational Health Data Sciences and Informatics (OHDSI) is an open, international collaborative that develops and maintains the OMOP Common Data Model, standardized clinical vocabularies, and open-source analytics tooling for observational health research. In KG-Registry, this entry represents the parent OHDSI ecosystem that publishes OMOP specifications and distributes standardized vocabulary access through Athena.

OHDSI is the open collaborative behind the OMOP Common Data Model, the OHDSI standardized vocabularies, and a broader ecosystem of open-source methods and tools for observational health research.
This KG-Registry entry is intended to capture the parent OHDSI/OMOP context that
ties together the data model and the standardized vocabularies. The vocabulary browsing
surface itself is represented separately in the existing athena resource.
The main OHDSI site for community information, documentation, working groups, and software links.
The community-maintained OMOP CDM specification and implementation artifacts, including documentation and DDL downloads for supported database platforms.
The OMOP CDM page also points to the main software stack used to build, validate, characterize, and analyze OMOP-formatted data, including HADES, the CDM R package, Data Quality Dashboard, Achilles, ARES, ATLAS, Rabbit-In-A-Hat, Feature Extraction, and Cohort Diagnostics.
The standardized vocabularies used across OMOP clinical domains and distributed through Athena for browsing and download.
