Resources
A curated, deduplicated directory of OHDSI tools, references, and working-group links. For task-specific guidance (EHR extraction, terminology mapping, data governance), see ETL & Mapping Guidance.

• CDM GitHub — source repository for the CDM specification and DDL scripts.
• Themis convention library — community conventions for consistent ETL/mapping decisions across the OHDSI network. Also on GitHub.
Vocabulary & mapping tools
• Athena — the OHDSI vocabulary repository, used to browse and download standardized vocabularies for mapping source codes to OMOP concepts.
• USAGI — a tool to support the manual mapping of source codes to standard OMOP concepts.
• SqlRender — translates SQL across database dialects (SQL Server, Snowflake, PostgreSQL, etc.) for use in OHDSI tools and cohort definitions.
Analysis & quality tools
• Atlas Demo — try Atlas, the OHDSI cohort definition and analysis platform, without installing anything.
• Data Quality Dashboard — automated data quality checks against the OMOP CDM.
• ACHILLES — characterizes and profiles an OMOP CDM database. See also the Achilles wiki.
• HADES — the Health Analytics Data-to-Evidence Suite, OHDSI’s collection of open-source R packages for observational research.
Learning
• OHDSI ETL Tutorial — walkthrough materials for building an ETL pipeline to the OMOP CDM.
• EHDEN Academy — free online courses covering OMOP CDM, vocabulary mapping, and OHDSI tools.
• [Boyce Data Science] (https://www.boycedatascience.com/research-tools#bds-omop) - an excellent suite of tools and resources built by Dr. Danielle Boyce
