====== OHDSI Phenotype and Knowledge Library ======

==== Overview ====

OHDSI seeks to create a validated content library to enable reproducible research.  The library touches on the activities of many working groups, including APHRODITE, CIRCE, ATLAS / HERMES, LAERTES, PENELOPE, and the PheKB definition effort.  In addition to these activities, the Library has its own standalone requirements.  This project page is designed to faciliate defining the requirements of the OHDSI library.


==== Library Requirements ====
**
//Content Types//**
  * Concept Sets (e.g., concept codes meaning Low Density Lipoprotein (LDL)) 
  * Clinical Facts (e.g., Elevated Cholesterol (e.g. [LDL Concepts] > 130 OR [Total Chol Concepts] > 200)
  * Phenotypes (e.g., Patients with Hyperlipidemia)

Note that Clinical Components are not currently implemented in OHDSI so would require development effort.
