Thank you for your comments.
At this point the code serves the purposes of the gimed metadata editor.
Of course the utility is going to be re-written if it is to be included
in gdal (with different license).
All your suggestions are very welcome and will be taken under consideration.
I will look into what you propose with the CSV driver. Looks interesting.
As for your last question, this has to be handled with some kind of
external parameter from the user.
