Federated Aggregate Cohort Estimator (FACE): An easy to deploy, vendor neutral, multi-institutional cohort query architecture

- FACE is a federated, multi-platform approach for clinical study cohort estimation.
- Data is aggregated from both i2b2 and Virtual Data Warehouse (VDW) data models.
- The architecture helps meet IRB and security requirements easily with local control.
- RESTful web services preserve security, logging, and features for i2b2 sources.
- The virtual machine delivery model reduces the burden at each data sharing site.
