Tetsuro
Basically we need to write a little code that transforms the biolod
RDF metadata to the CKAN JSON format.

To do a one-off import then you should use the CKAN API [1]. You could
do it in Python and use the ckanclient library [2].

Or to do a daily automatic import you would write a harvester. Derive
from the base class [3]
and write a custom "_create_or_update_package" method.

This way has the advantage that the original RDF is stored alongside
the CKAN version. We'd be happy to install this harvester in
thedatahub.org or another CKAN instance.
