Exported UTI for package / package

My Cocoa document-based application opens and writes its own packages / packages.

Is this considered a proprietary format that needs to be exported through exported UTI ( UTExportedTypeDeclarations)?

If so, what should be the values ​​for:

  • Compliant ( UTTypeConformsTo)
  • Mime Types ( public.mime-type)
  • Types of Pboard ( com.apple.nspboard-type)
  • OS Types ( com.apple.ostype)

Finally, should the identifier of the exported UTI identifier ( UTTypeIdentifier) be the same value as the document type identifier ( LSItemContentTypes)?
