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.

cp <archive>/<datetime>/* /priv-file-repo/Production-History

cp cumulative_ncitconcept_history cumulative_ncitconcept_history.bak

cat ncitconcept_history >> cumulative_ncitconcept_history

The cumulative_ncitconcept_history must be reformatted in order to be loadable into the LexEVS terminology server.   

 .  This is done using Format_History.  The output file "concept_history.txt" should be copied back to the Production-History folder as a backup.
