[ckan-dev] Fwd: Harvesting Group data

Fri Dec 6 09:07:45 UTC 2013

Hi Philip,

I'm not entirely sure, but in our harvesters we used to specify groups as a
list of group names and not as a list of dictionaries, so the data should
look like this:

{'authors': [],
 'extras': {'alternative_title': u'Proteomics informed by
transcriptomics raw dataset ',
            'author_string': '',
            'contributor_string': '',
            'doi': u'10.5523/bris.12mjtnrtsdjfs17sl4pq2ucqrk',
            'language': u'eng',
            'publication_date': '29 Nov 2012',
            'publisher': u'University of Bristol'},
 *'groups': ['medical-and-veterinary-**sciences'],*
 'id': '12mjtnrtsdjfs17sl4pq2ucqrk',
 'license_id': 'uk-ncgl',
 'name': '12mjtnrtsdjfs17sl4pq2ucqrk',

I think it even doesn't matter if it's the group's name or id, both should
work.

Regards Stefan
