Using SDC to describe files of works/objects without creating Wikidata items for them

Structured data that describes the file, and structured data that describes the work or object, can be distinguished by using qualifiers:

• Qualifier for statements that pertain to the file: applies to part (P518) Wikimedia Commons file (Q51954352)
• Qualifier for statements that pertain to the work or object: applies to part (P518) analog work (Q112134971)

Using these qualifiers, the structured data of the file can contain data about both the file (e.g. its creation date, photographer, source, ...) and the object depicted in the file (e.g. its creation date, collection, inventory number, ...). Both sets of structured data can coexist.
