A report for the Mix'n'match tool. This page will be replaced regularly! Please note:
- If you fix something from this list on Wikidata, please fix it on Mix'n'match as well, if applicable. Otherwise, the error might be re-introduced from there.
- 'External ID' refers to the IDs in the original (external) catalog; the same as the statement value for the associated property.
