source for new object with info taken from other mapped objects

Let's say somebody maps a school. The school has the info about the name of the village where the school is located. But the village isn't mapped with a name (there may be a node already stating it is a village, but no name yet).

My question is:

If I add the name to the village node, what should be the best source tagging?

I use to tag it as source=osm, but maybe there are better tagging schemas, like source=node 123456789, source=changeset 987654321 or similar.

I think I've used source=inference for similar cases (it being implicit that the inferences are made from OSM data).

It looks one possibility. I've checked taginfo and only 86 appearances of inference (although some others combined with other values). But I've seen that there are more than 3900 of source=OSM...

When it comes to noting your sources, nobody will ever complain to you that you're being too specific. If you want to put "node 123456789" go for it. If, after a month of this, you're feeling lazy: "OSM" is fine... Nobody will be able to know exactly where the info's from, but they'll get the general idea.

"inference" imo doesn't really say anything about the source. It's a fancy way of saying "source=I figured it out". Figured it out from what? Inquiring minds wanna know. It's still better than nothing, of course.
