[ckan-discuss] csw harvester

Mon Apr 29 09:48:24 BST 2013

Ketty,

The error message "local list type: A type, derived by list or union,
must have the simple ur-type definition as base type, not
'{http://www.opengis.net/gml}doubleList'" is due to a bug in libxml
which is fixed in 2.9.0 (released Sept 2012). There are instructions
for updating in the readme:
https://github.com/okfn/ckanext-spatial/blob/master/README.rst

The URL you need for the GeoNetworks server is probably:
http://myckaninstance.net/geonetwork/srv/en/csw
instead of what you have:
http://myckaninstance.net/geonetwork/srv/en/csw?request=GetRecords&
