[datahub-discuss] Datahubio outdated datasets

Mon Aug 18 19:56:10 UTC 2014

Tim,

I thought about this. In that case it should be clearly possibly to see the
border between the historical metadata (which point to non-existent
datasets) and the actual metadata. The three possible ways at the moment
are:
1. Special tag
   + easy to add (everyone can add tags to his/her datasets)
   - tag space is quite big http://datahub.io/api/3/action/tag_list
   - tag descriptions are somewhat lacking
http://datahub.io/api/3/action/tag_show?id=access-commercial (is it
possible to have some more metadata for tags?)
   - "Historical" and "historical" are two different tags (i.e.
case-sensitive) - users will have several tags in the end

2. Special group
   + no groups at the moment http://datahub.io/api/3/action/group_list
   + group can have a description
http://demo.ckan.org/api/3/action/group_show?id=data-explorer
  + user can only choose from existing ones it seems (can't test it,
because no groups exist on datahubio)
   - I couldn't add a group to my own dataset
   - was it deprecated in favor of "organizations"?

3. Key/value pair (custom field)
  - No description for the field
  - Case-sensitive and need typing from dataset maintainer.
  - I created a key/value pair for my dataset, now can't delete it. Looks
like bug =\

Therefore, I would go for creating a special group (organization?) for the
historical datasets, if we want to keep them.

Kind regards,
Ivan.
