[GeoNode-devel] Non ISO Metadata Topic Categories and Geonode Behavior

[Patrick Dufour]

Good afternoon, Eduardo.

Could you briefly recap the relevant discussion during the sprint?  I
missed that conversation.

That is the expected behavior.  We wanted to be sure that if you
imported data from a source that isn't following that ISO standard
closely that the import will work rather than throwing an error.
GeoNode will match an existing category if possible and will create a
new category if needed.

I think my preference is to maintain that existing "default" behavior.
However, I think a flag in settings like "CATEGORIES_STRICT=False"
would work.  If CATEGORIES_STRICT is true, then if a category doesn't
match on upload/import an error is thrown.  If CATEGORIES_STRICT is
false, then the existing behavior goes.

Regards,
Patrick
