Both are only a single metadata. Each UTI has an associated human- readable description in the same way it has an array of associated extensions… this is visible in Apple spec. Behind the scene, you have an UTI db, you just query the db to know the various fields bound to a particular UTI. > - Creator What do you mean by Creator? The application which 'owns' the document (most of time by creating it) or something different. If you mean the first case, it's probably better to call it Default Editor/Viewer (or simply Editor/Viewer). The user should be able to modify it. This won't be stored in term of metadatas strictly speaking, but like UTI description this would be stored in a specific db which relates each UTI to an Editor and a Viewer. > - Creation Date > - Last Modification Date > - Last Accessed/Opened Date > - File size > - Other users/devices sharing this Document Not sure to understand.

All document-type specific metadatas like Authors, Copyright, Summary, Languages, Company and more for a text document. EXIF and IPTC for pictures. Ditto with sounds, videos. We should probably make some metadatas like Authors, Copyright available for any elements.
