Yes it is "DC AND other AP"
Specifically, OAI-PMH requires oai_dc:
http://dspace.mit.edu/oai/request?verb=ListMetadataFormats
http://dspace.mit.edu/oai/request?verb=GetRecord&metadataPrefix=oai_dc&identifier=oai:dspace.mit.edu:1721.1/44628
http://www.openarchives.org/OAI/openarchivesprotocol.html#MetadataNamespaces
<snip>
For purposes of interoperability, repositories must disseminate Dublin
Core, without any qualification. Therefore, the protocol reserves the
metadataPrefix `oai_dc', and the URL of a metadata schema for
unqualified Dublin Core, which is
http://www.openarchives.org/OAI/2.0/oai_dc.xsd. The corresponding XML
namespace URI is http://www.openarchives.org/OAI/2.0/oai_dc/.
