Tgr added a comment. `?` does not come from any internal logic in CommonsMetadata - if the author or source is not specified, the relevant key will simply be missing from the response:
- https://commons.wikimedia.org/w/api.php?action=query&titles=File%3ABathsOfCaracalla.jpg&prop=imageinfo&iiprop=extmetadata&format=jsonfm - https://commons.wikimedia.org/w/api.php?action=query&titles=File%3ADomusAurea.jpg&prop=imageinfo&iiprop=extmetadata&format=jsonfm The required logic is: `AttributionRequired` is true(-ish - https://phabricator.wikimedia.org/T86726) but `Artist` and `Attribution` are both missing. (This assumes you are using the Attribution field, which did not exist at the time the above patch was made against OCG.) I can put this logic into CMD if you prefer that.
