Data extraction client?

Good.

A nice way to everything is working as it should, would be to import a
data set and export it again, and verify that the content did not
change.  Do you think that would be possible with nikita and the API?

I suspect the systemID values will change, if there is no way to set
them.  Is there any control of the uniqueness of such IDs?

Right.  Perhaps we should have importing the correct one as a short term
goal, along with an extraction program?

I'll see what I can do.  I first plan to add more data using my test
script, and try to verify that the field content is controlled for
invalid and valid values. :)
