OSMPID / OSM Persistent IDs
/ Endpoint · GET /validate

Validate an OSMPID

Check a stored reference against current OSM state. The validator parses the string, resolves the object, and reports whether the version, child elements, or tags have changed — returning a refreshed ID when they have.

Reference GET / validate
Examples:
ID components
element_type required
element_id required
version required
latest_child_timestamp conditional
tags optional
Outcomes
Unchanged Version, children, tags all match.
Changed A refreshed OSMPID is returned.
Deleted Object no longer visible.
Unknown type + id never existed.
Malformed 422 — string failed to parse.

Resolved against current OSM state by the osmpid-service — the UI re-uses the service's /validate logic and never re-implements it.
