Here are two Python scripts that:

• Revert simple OpenStreetMap changesets. Way and relation structural changes cannot be reverted, all other changes can. For example, if you deleted a lot of objects, or changed many tags at once.
• Restore an old version of given object(s). All of their deleted references are restored as well.

If there are no errors, scripts would ask you for OSM login and password (which are immediately forgotten) and upload the changes. Alternatively you can redirect output to a file and open it in e.g. JOSM for reviewing and uploading.

pip install --user simple_revert

Specify changeset ids as the simple-revert script arguments. E.g.

simple_revert 12345 12346 12348

To list recent changesets by a user (e.g. you), specify their name as the only argument:

simple_revert Zverik

To restore an old object version, pass its type, id and version to restore_version. For the first argument you can use following formats:

• n12345 for a node, w2342 or r234234 for ways and relations.
• node/12345, node.12345 or even "way 2343" (note the quotes).
• https://www.openstreetmap.org/node/12345 or any other similar link.
• https://api.openstreetmap.org/api/0.6/node/12345/6 includes a version to restore.

Version number should be either a positive integer, or a negative, relative to the last version. E.g. this command will revert the last change to a node:

restore_version n12345 -1

To get a list of recent versions, run the script without a version argument.

You can pass several objects to restore them all in one changeset:

restore_version n12345 -1 w1234 -1 w1235 -1
