you could define certain patterns you expect to be typical for imports
and then elaborate through all the changesets and flag them automated
or manual (you could exclude the changesets which are already flagged
by the uploader as bot-edit to reduce the computational effort). Then
you could use the full history to find out for every object if they
had been created in an import and whether they have been modified in
the meantime. I guess this will take some time ;-)
