METS Profiles are intended to describe a class of METS documents
in sufficient detail to provide both document authors and programmers
the guidance they require to create and process METS documents
conforming with a particular profile.
Institutions creating profiles
for their METS objects may register those profiles with the Library
of Congress Network Development and MARC Standards Office after
they are approved by the METS Editorial Board; such profiles will
be made publicly available so that those wishing to produce METS
documents in accordance with a particular institutions' requirements
may examine them.
