Hi Alexander,
I just wanted to take the opportunity to discuss a side-comment about
"Marc-Based JSONs" you made on a different thread ("A propos de
Z39.50". Starting a new thread as I am deviating from the original
topic):

How does this MARC JSON looks like? How "nice" is it?
Internally we have been briefly musing about the various ways to encode
MARC in JSON. It would be interesting to know which path you have
chosen.
For the record here are some possibilities explored:
1.
<http://dilettantes.code4lib.org/blog/2010/09/a-proposal-to-serialize-marc-in-json/>
(contains some discussion on the various alternatives)
2. <http://www.oclc.org/developer/content/marc-json-draft-2010-03-11>
3.
<http://dilettantes.code4lib.org/blog/2010/09/a-proposal-to-serialize-marc-in-json/>
("Deprecated")
4. Libray of Congress added some JSON export of their photos cataloged
in MARC, but do not seem to have released any spec:
<http://www.loc.gov/pictures/item/2008660390/marc/?fo=json&at=marc>
They also have this hybrid output:
<http://www.loc.gov/pictures/item/ggb2004008550/marc/?fo=json>
<http://phenotypical.com/library-of-congress-prints-photos-goes-json>
5. Various more "user-friendly" alternatives, using labels instead of
MARC codes.
There have been some (old) prototype for a JSON export in Invenio here:
<http://invenio-software.org/repo/personal/invenio-jerome/commit/?h=bibformat-json-output&id=ac8c8d3c3c8e5d45274b0ba83af784009089ff37>
Some might have already been a bit further than the above attempt.
We might also ask the "users" mailing list for the preferred type of
JSON output.
Best regards
