[GeoNetwork-devel] GeoNetwork harvesting

I have been trying GeoNetwork harvesting for a while and I'm a bit
disappointed with the results, as I could not fully replicate a remote
category in my local node:
- None of the tested protocols (GeoNetwork, OAI, CSW) is able to
retrieve the metadata thumbnails
- GeoNetwork and CSW protocols are not able to filter by GeoNetwork
category (at least this option is not available from the UI)
- OAI protocol is able to filter by GeoNetwork category, but it
retrieves a small part of each metadata record when using oai_dc
prefix. When using iso19139 prefix, some records are not harvested due
to bad XML. I guess this is not strictly a GeoNetwork error, but
malformed metadata on the remote node.

Questions:
- Is it feasible to implement the harvesting of thumbnails on any of
the protocols? If yes, could you provide some hint on how to do it and
what would be the relevant files to modify?
- If we implement a filter by category in the Geonetwork protocol,
would you be interested on including this feature on Geonetwork?

Thanks in advance,

César
