statistics about source=* in changesets

4

Does anyone know if we can find anywhere some statistics on the tag source=* used on the changeset? I mean, for example:

  • percentage of changesets having this tag
  • amount of primitives in the database that have at least one changeset tagged with a given source=* value

It can be usefull for measuring the use of a datasource, in a more precise way that only use taginfo (that is great btw).

Thanks

I'd be very interested in this as well. ChangesetMD might help out with this, but it still requires some database know-how: https://github.com/ToeBee/ChangesetMD

The source tag is very seldomly used, about 0.5% of all changesets uses the source tag. But 2% of all changed/created/deleted objects have a source tag on the changeset, according to num_changes in the changeset header.

This is based on a small perl script (feel free to use it, it will be buggy).
