Import tags from a different database

[George Koulomzin]

Thomas,

It is possible to write to the DB directly (but certainly not 
supported).  I've been playing around with java code to massage my 
groups (consisting of raw + jpg), e.g. so that they always have the same 
type of image file (e.g.  jpg or raw) as the leader (that's the one you 
see when the group members are hidden), and to make the tags and labels 
the same for the entire group.

If the tags you wish to introduce are are simple, it should not be too 
difficult.  If the tags are hierarchical, it is more complicated, since 
you must build a virtual tag tree in the db.

Another possible approach might be to create/modify the sidecar files 
with something like perl.  This would lessen the risks to your db.
