Sorry mixed up references/subjects but you got it right.
Wow, did not think that I did open up a big pot. I did not think about different layers and did not try it yet but nice if it is working.
- Not touching the other layer is perfect.
- I am not sure if you really need the distinction per match as I think it is much faster to do several conflation actions than to check match after match.
- My request was to move tag/membership from reference to subject but keeping the reference object in place without tag/membership.
- To only copy tag/membership in the same layer leads to duplicate data which does not seem to be right.
- Only replace geometry but removing/deleting all tags/memberships is not needed as it is not hard to manually delete them first. It also leads to some other direction as for me the most difficult action is the moving of tag/membership. Only useful with different layers.
I am still in favour of setting this option either in the reference/subject dialogue or in the toggle dialogue.
- Replace geometry (removes reference if it's in the same layer as the subject)
- Keep reference object (only move tag/membership)
- Keep copied tags from reference (only if 2 is checked and different layers)
By default 1 will be checked (3 is N/A) if reference and subject are in the same layer otherwise 1 to 3 will be checked.
