Hi Hian,

This is how a basic function looks like in libckan:

---
def name_action(client=client.Client(), id=''):
    resp = client.request(action='name_action', data=args)
    if not resp['success']:
        raise exceptions.CKANError(resp.error)
    return resp
---

For the moment, it raises a generic CKANError. The Client object (basically it is a wrap around a urllib2 http request and json utils) raises CKANErrors, too.

After I cover the whole get actions, I will think about a clever way to subclass CKANError according to resp.error.
