@Jura1:Hi, are you sure, that your change with URN formatter (P7470) is right? As i understand these identifiers, that's not true. Still there is warning about same identifier in more external ids. Skim (talk) 15:53, 29 October 2020 (UTC)

• It's the same formatter, not the same identifier. The assumption is that uuid would be unique in practice. Wikidata:Database_reports/uuid tries to find some exceptions. --- Jura 16:04, 29 October 2020 (UTC)
