Identifier in the metadata is a Dublin Core identifier, identifier in 
the header is a unique identifier within your repository.

Dublin Core is a list of unordered, repeatable string values (although 
you should use proper URIs, ISO dates etc. where applicable).

See the Dublin Core docs for what Type, Format, etc. are:
(Dublincore.org seems to be down atm so I can't check that's the 
description doc ...)

Header.identifier = "oai:myrepos:uniqueid10"

DC.identifier = "http://www.myrepos.com/item/10"
DC.identifier = "oai:myrepos:unique10" (i.e. you could also include the 
OAI identifier in the metadata)
DC.identifier = "New Order Journal, V202 30-40"
DC.type = "Text"
DC.format = "text/html"
DC.date = "2002-04"
and so on ...

All the best,
