Structural metadata is a type of metadata, which shows how a resource is organized and it's structure, like the order of pages in an e-book or even the tables that are in a database.
And administrative metadata, is a type of metadata that includes technical and rights information, like file type, creation date, usage rights, access controls and ownership.
Metadata is used to describe, explain, locate or otherwise make data easier to retrieve, use or manage.
