METS Profiles
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.
A profile is expressed as an XML document. There is a schema for this purpose. The profile expresses the requirements that a METS document must satisfy. A sufficiently explicit METS Profile may be considered a data standard.
