[ckan-dev] Allow CSW harvesters to define CQL filters

Tue Mar 18 18:23:14 UTC 2014

Ciao Adrià,

great, I see you merged the pullreq! Thank you :)

A point of discussion here: since now the harvested records may be filtered, an 
admin may want to create different sources pointing on the same server, but 
with different CQL filters. This may be done for instance for assigning different 
organizations or whatever to the different set of records.
This can't be done at the moment because you can't create more sources with an 
identical entrypoint URL. Should an issue be opened about the relaxing of this 
constraint?

   Ciao,
   Emanuele
