Metadata Encoding and Transmission Standard

METS is intended to promote the preservation of, and interoperability between digital libraries.

The customization of METS makes it highly functional internally, but creates limitations for interoperability.

These profiles document the implementation of METS specific to that institution helping to map content in order for exchanged METS documents to be more usable across institutions.

In 1998 this work was expanded upon by the Making of America II project (MoAII).

This revision was the foundation for the current METS schema, officially named in April of that year.
