Source Code for Ontology Management (ONT) Cell

In the chapter titled Install i2b2 Server-Common, you extracted the files from the i2b2 Core Source Code zip file into a directory of your choosing (YOUR_I2B2_SRC_DIR). One of the files extracted was a folder called edu.harvard.i2b2.ontology and it is in this folder where the files for the Ontology installation reside.
