Setting up a registry

[Sebastien Derriere]

Hi all,

For the CDS/VizieR publishing registry, it was implemented in PERL using as
a base libraries developed at Virginia Tech., but modified to retrieve 
metadata from
Sybase, then PostgreSQL databases to build records.
I guess the original source code has moved, but now is here :
http://www.husseinsspace.com/research/projects/xmlfile/

I'd rather do it in Python today, using a library like :
https://pypi.python.org/pypi/pyoai
(has anyone used this one?)

If you need to test your registry for compliance with the OAI-PMH protocol,
this is a link I found useful :
