EXIF(-like) data
editMetadata from files' EXIF information will be extracted upon upload and stored in Wikibase at Commons. The original EXIF metadata stays embedded in the file itself, unmodified, even if the extracted metadata in Wikibase is modified by the Wikimedia Commons community.
Non-image media files (e.g. sound and video files, 3D files…) strictly have no EXIF data, but similar metadata applies to them which can be stored in Wikibase at Commons in the same way. More generic properties will help to describe various file types in a similar way.
