Mission
Ingest data from their native formats—PCORnet, ACT, OMOP, TriNetX—and harmonize the datasets into a common data model (CDM) based on the OMOP 5.3.1 standard to maximize analytics.

Office hours are held on Thursdays from 9:00-10:00 am PT/12:00-1:00 pm ET to answer data ingestion questions and address issues. (Regulatory paperwork does not have to be complete to attend.) Register Here.

FAQs
The Phenotype & Data Acquisition team will contact the contributing sites directly if there are concerns with the data ingestion and harmonization process.
Existing OHDSI OMOP data conformance tools and processes are all available in the N3C Data Enclave and are run on the data prior to ingestion into the full dataset. The data quality checks are a hybrid across all data models.
Common data models used by sites are consolidated and harmonized to the OMOP common data model and then ingested into the N3C Data Enclave as a new dataset.
