Page History
The publishable history files will be located at /priv-file-repo/protege/archive/Production-History. The source history files will be located in /priv-file-repo/PROD/NCIT/<hash>/<datetime>. The operations team will be responsible for updating the publishable history directory with the appropriate sources source files and generating a history file that can be loaded into LexEVS.

EVS History
This file The cumulative_ncitevs_history is the detailed history written for internal purposes. It includes editor names and the exact date of any and all modifications to the concepts. Protege creates a full, cumulative EVS history with every history export. This file needs to merely be copied from the source directory to the Production-History, overwriting the file that is there.
Concept History
The ncitconcept_history is a scrubbed version of history that removes editor names and eliminates duplicate modifies within the same month. While internal review might find it important that a concept has been edited 5 times in a month, external users are only informed that there have been modifications since the last release. The monthly history process examines the raw ncitevs_history and throws out all of the extra, uninformative modify records. The resulting ncitconcept_history only shows records since the last history export. It needs to be manually appended to the cumulative_ncitconcept_history in the Production_History folder.
The cumulative_ncitconcept_history must be reformatted in order to be loadable into the LexEVS terminology server.
