I'm looking for a solution to get a version identifier in a METS representation of a Digital Object. I could not find anything related to versioning in the METS schema.
Naively i thought something like this would be possible:
<mets:mets xmlns:mets="http://www.loc.gov/METS/" OBJID="some-id-xxx" VERSIONID="version-xxx" LABEL="some-label"> ... </mets:mets>
But there is no such thing as VERSIONID in the METS specs
Is there a general way to do this? Does a new Version always require to be created with a distinct OBJID and a reference to the former Version in the Source metadata?
