         This structure could be extended in the future to add EXIF and IPTC metadata as child nodes.
         For example, EXIF metadata is structured as tags in directories, where the directories form something like namespaces,
         and which are used by different camera vendors to store custom metadata.
         This structure could be mapped with each directory (e.g. "EXIF" or "Nikon Makernote" or "IPTC") as the name of a child node, with the EXIF tags values stored as either properties or child nodes.
