We will most likely ask for the original identifier. The template
structure on Commons is already based on states, so e.g.
{{Kulturdenkmal Hessen|12345}} works already, the database ID for that
image will then be 06-12345 with 06 being the code for the state Hesse
(this is, as I said, an official code scheme, all municipalities in
Hesse have a code starting with 06).
As far as I know today, there are only two states that have numbered
lists on lower levels. We're not exactly sure how to handle them on
Commons even, but it will either be something like {{Baudenkmal
Nordrhein-Westfalen|Köln|12345}} (which I prefer) or {{Baudenkmal
Nordrhein-Westfalen|05 3 15 000|12345}} with the 05... being the code
for Cologne. But since all municipality codes are known, we can ask to
provide the municipality and monument ID, a simple matching table will
do the rest. Same for areas where the counties keep the lists and
assign the IDs, just with a shorter code as prefix (in the code for
Cologne, 05 is the state, 3 the district and 15 the county).
When uploading directly from the lists, it's obviously much easier
since we can provide all necessary information automatically.
You can see that this method has a clear advantage over generating new
IDs from scratch: It keeps the official IDs and is based on an
official code scheme, so it's not an OR issue to actually display the
prefixed IDs in some Tools. On Wikipedia, only the official IDs are
shown and included in the lists.
