In fact a link like 
http://arc.cs.odu.edu:8080/dp9/getrecord.jsp?identifier=oai:eprints.rclis.org:830&prefix=oai_dc&output=redirect
is exactly what i need.

Why do I need a similar service ?

I'm developing a service provider to collect the OAI-PMH Data Provider 
about Library and Information Science.
I'm studing how to add OpenURL to my service provider. I want that my 
service provider will be a "Source" in OpenUrl jargon, like ArXiv.
With the help of Simeon Warner I'm reading the code of ArXiv about OpenUrl.

ArXiv sends to the OpenUrl resolvers (like OpenResolver from Andy Powell) 
only the oai-identifier. The resolver reads the oai-identifier and it 
understands, from a specific OpenUrl field [called 'sid'], that the 
oai-identifier cames from ArXiv.
After those operations, the resolver send a query to a specif gateway of 
ArXiv and it recives an XML with all metadata in rfc1807.
Now, the resolver parses the XML, it extract the metadata, and after it 
builts the "special effects links"

Send only the oai-identifier is very easy for me, but it is not possible 
that resolvers have specific gateway for all OAI-PMH Data Provider. So it 
is better to have only one service to do this redirection

For me, now, I need only those archive:

Caltech http://caltechlib.library.caltech.edu/perl/oai2
ArchiveSic http://archivesic.ccsd.cnrs.fr/perl/oai20
Tel http://tel.ccsd.cnrs.fr/perl/oai20
MemSic

DLIST

biblio-eprints http://biblio-eprints.bo.cnr.it/perl/oai2
LDL  <http://drtc.isibang.ac.in/oai/>http://drtc.isibang.ac.in/oai/
E-LIS <http://eprints.rclis.org/perl/oai2>http://eprints.rclis.org/perl/oai2

Many are still present in DP9, can you add the missing ones ?

For me DP9 is quite useful as service provider. I can see it as "CrossRef 
for OAI-PMH Data Provider"

Thanks for all.
