[ckan-dev] Accessing Data.gov's CKAN API through JavaScript

[Alessio Dragoni]

It might be because catalog.data.gov is using  different ckan version of
demo.ckan.org

You can check it with http://catalog.data.gov/api/action/status_show

You can use the legacy v1 api in case you need just informatin about
groups. Such api is present in all versions
