Hi,

In Ukraine, we have two problems Wikidata is not able to deal so far:

1) Our monument IDs are the ones we invent ourselves. We have 4 types of monuments times 27 regions (+1 nationwide list), some of these lists have identifiers, some not. Identifiers are not unique even within the same list, e.g. one list has a few monuments with identifier "1", and in total we have several dozens monuments with identifier "1". Thus our governmental IDs are pretty useless, but does Wikidata accept original IDs created by Wikimedians?

Oo.
That's gonna be complex. Not sure how to deal with that. You can ask on https://www.wikidata.org/wiki/Wikidata:Property_proposal for a property « Wiki monument ID » for creation but not sure if it will be accepted (in fact, pretty sure it won't but I think it's worth the try).

2) Many of our monuments do not have precise addresses like "city, street, house number", but something like descriptions, e.g. "1.2 km north of the railway station, 500 m east of the road to (some village), 300 m west of the cemetery"  or "in the centre of the village, in the park behind the shop". Is there a way to describe this on Wikidata?

It is a bit exotic but there will be no problem to use P969 for that : https://www.wikidata.org/wiki/Property:P969 (it's a string type so you can put whatever you want).

In addition, we would be glad to know if there are any tools to migrate 70,000+ items to Wikidata, as doing this manually would be probably impossible... If not, we would be still interested in old good erfgoedbot who  did its job pretty well in our case.

Same question for France.
We have already a lot of monuments in Wikidata but not all of them (generally, all monuments with an article on fr.wp have an item on wikidata).
We have a project on Wikidata : https://www.wikidata.org/wiki/Wikidata:WikiProject_France/Monuments_historiques but nobody there has a high wikidata-fu / technic skills.
