[ckan-dev] CSW Harvesting from GeoPortal and GeoNetwork

[Konrad Reiche]

Hi Ryan,

I had problems with the Error gathering the identifiers from the CSW 
server ['NoneType' object has no attribute 'find']  as well. Here is 
what worked for me:

Check what version you are using with

pip freeze | grep -i owslib

For me OWSLib 0.4.0 works, so I suggest you uninstall your current 
OWSLib installation with

pip uninstall owslib

and install the 0.4.0 version from the GitHub repository:

pip install -e git+https://github.com/geopython/OWSLib.git@0.4.0#egg=OWSLib

When I tred the latest version 0.5-dev the error stayed the same. I am 
using CKAN 1.8
and Harvest + Spatial [latest] as well.

Best,
Konrad
