Was talking today about interoperability with GeoCommons/GeoIQ, and one thing they use for lots of federated search is OpenSearch.
Realized that we may get it 'for free' with GeoNetwork. Looked in to it and looks like we're close: http://demo.geonode.org/geonetwork/srv/en/portal.opensearch The only major problem is it refers to localhost instead of the web location. I guess that's something that has to be configured in GeoNetwork? And then it's generic metadata that could be better configured. Would be nice to have it configured somehow automatically out of the box, or at least include configuration instructions in the set up. C
