Hi Jiann-Ming,

Sorry for not being more clear:  Our XSLT produces Qualified Dublin Core as 
RDF/XML which should mostly conform to the guidelines for "Expressing 
Qualified Dublin Core in RDF / XML" 
(http://www.dublincore.org/documents/2002/04/14/dcq-rdf-xml/).  This is the 
reason for the rdf-prefixed tags.  This format cannot be used directly with 
OAI, mostly because of the lack of an XML Schema.

The RDF/XML output of our transformation will need to be further processed 
(dumbed-down) to produced simple, unqualified DC before it can be used with 
OAI.  We also have an XSLT transformation which is not posted on SourceForge 
for doing this.  If you like I can also post this transformation which takes 
the qualified DC RDF/XML and turns it into OAI compatible DC.

Sorry for the confusion.
	Tom
