[ckan-dev] Fwd: Issues using Geo plugins

Tiago,

Great to hear that helped.

The data.gov.uk harvester is currently set to:

ckan.spatial.validator.profiles = iso19139eden,constraints-1.4,gemini2-1.3
ckan.spatial.validator.reject = true

If you're not on the dgu branch of ckanext-spatial already then you'll
need to switch to it to get these validators and the second option.

However that still gives us 48 validation errors for spatialni.gov.uk
data. This is not uncommon - producing XML that is valid Gemini2
appears to be tripping up a lot of publishers. UKLP makes some effort
to help, but at the end of the day it is NI's responsibility.

It sounds like the datasets you see on data.gov.uk were harvested
before we switched on the 'rejection', which was April. Previous to
this, datasets were still harvested into CKAN even if they didn't
fully validate. You can do this with this config:

ckan.spatial.validator.reject = false
