The METS schema is a standard test for encoding descriptive, administrative, and structural metadata regarding objects within a digital library, expressed using the XML
schema language of the World Wide
Web Consortium. The standard is maintained by the METS Board
in collaboration with the Network Development
and MARC Standards Office of the Library of
Congress and started as an initiative of the Digital Library Federation.
