[ckan-dev] Metadata fields

[Stefan Oderbolz]

I guess if you want to do this, you need to change the default schema of a
dataset. Although this might be possible, I would still use the extras
field. Because this ensure compatibility with other CKAN instances that you
might want to harvest, or that might harvest you. And there is not really a
disadvantage with using the extras field, only that it requires you to save
flat data (i.e. nesting is not well supported and generally discouraged).

Please correct me if I'm wrong about that :)
