[Dspace-general] (no subject)

Hi,
I have a problem with OAI-PMH of DSpace.
we have a digital repository (https://drtc.isibang.ac.in) and also a
harvester (http://drtc.isibang.ac.in/sdl)

When we use in our submission 'Citation', we got into problems.

DSpace uses Qualified Dublin Core for submission and exposes UnQualified
DC for OAI-PMH.

When we use OAI command ?verb=ListIdentifers&metadataPrefix=oai_dc

we will have
<dc:identifier>Citation</dc:identifier>
<dc:identifier>http://hdl.handle.net/1849/212</dc:identifier>

Now when we harvest our DL with our harvester (we use PKP Harvester), it
picks up citation as URI, not the handle. (Citation appears first rather
than uri)

I changed OAICrosswalk.java to suppress the element idetifier.citation and
exposed only identifier.uri, to get the desired result.  But somehow I am
not comfortable supressing some information, rather I would have preferred
to expose first identifier.uri then identifier.citation.  This requires
more change in the code of OAICrosswalk.java.

I believe that DC itself should give an element exclusively of Handle as
this is going to be a very important and unique identifier.

Has anybody come across this problem?
Does anybody think they have better way to deal with this problem?

regards
ard
