Jerry may want to give his thoughts on this (since he wrote the
schemas). My take is the following.
I would see PREMIS metadata in the admSec if using mdWrap or could be
pointed to if using mdRef. There might be 2 different ways of doing this
and we would expect people to experiment with them.
1. Include event metadata (from event.xsd) in digiProv under admSec and
technical metadata in object.xsd under techMD. One could include both
PREMIS defined metadata and more specific MIX metadata within techMD using
the appropriate namespaces in the METS document. PREMIS technical metadata
is that which applies to all or most types of digital objects, while MIX
is for image material. In the revision of the NISO data dictionary
(Z39.87) there was an attempt to use the same element names for those
elements that overlapped with PREMIS ones.
2. Bundle all PREMIS metadata together using the PREMIS container schema
(premis.xsd) and put under admSec/techMD.
Jerry had said that one of the advantages to the entity-specific schema as
they are drafted is that you have a bit more freedom to pick and choose
which parts of the PREMIS metadata set you want to use, and where you put
them. He included the slightly redundant XML ID/IDREFs allowing you to do
things like link a rights statement to a related object, so that you could
have an independent rights record within the appropriate portion of METS
and have it point to a technical metadata record in which you might have
PREMIS Object metadata. He had said that it would be best to let people
try to use the schemas as is and then start working on a more METS
specific implementation once there's experience using the schemas.
