Objective: Standard encoding of descriptive, administrative, and structural information for objects within a digital library using METS—Metadata Encoding and Transmission Standard. METS enables digital media files to be responsibly managed and transferred by bundling the appropriate metadata with the files.

Overview: This standard is powerful and flexible, with a growing number of uses. RLG, in addition to participating on the METS Editorial Board and exploring best practices for METS' use in certified digital archives, promulgates the standard by using it in services like RLG Cultural Materials.
