[OSM-dev] Identifying when a tag was added

[Paul Norman]

I have a list of a few hundred nodes with a particular tag, say foo=bar. All
the nodes are version 2 or greater.

I want to identify either the earliest version with that tag or which
versions have that tag.

For my case it is acceptable to call /history from the API because it is for
editing.

Has anyone written anything like this?

This is to identify what versions of an object need to be redacted.

I will also be doing this with ways, but there are complications with nodes
that I haven't fully worked out yet.
