[ckan-discuss] Questions for "RDF/XML" of CKAN page

[Pablo Mendes]

David,
very helpful message for all of us! I have a similar need. I want to pull
all of the metadata in data.gov.uk about datasets that contain RDF into
CKAN.net. There are about 160 of them.

http://data.gov.uk/search/apachesolr_search?filters=sm_resource_formats%3ARDF

Would the same advice apply?

Cheers,
Pablo
