It is best if you always tell LexEVS if a terminology is the default, even if you only have one copy of it loaded. Some queries, like queries to terminology metadata, do not work without setting a terminology as the production copy. You do this by tagging a terminology. The LexEVS Administrative GUI has a button to change the tag of any loaded terminology. The LexEVS loader commands have a flag that can be used to set the tag. The tag is a simple string. You can assign any tag you want, but the string recognized by LexEVS is "PRODUCTION" (all caps, no quotes). You should get in the habit of marking loaded terminologies as PRODUCTION. The opposite of that might be "TEST" or just left blank. The reason for having the tagging function is to allow for multiple versions of the same terminology to be loaded with no ill effect because one of them can be designated as the default with this approach.
