It's great you have this fine API!
thanx for your effort - this' all working now :)

why, no, good idea, that is feasible for us - just tested this, it works:

wget
'http://ckan.net/api/1/search/package?filter_by_openness=1&publishingInstitution=http*//lobid.org/organisation/DE-605*'

Being myself a programmer I eventually *had to* think about tuples
because searching in tuples would be easier for solr. But as far as the
machines are not complaining I won't either ;)

these may be more elegant when it comes to more complexity, thanks.

oo
