[ckan-dev] using a java client to upload files to a dataset created through the datahub.io website

Thu Jan 24 09:34:32 UTC 2013

Hi,

Yes, sorry Sean is right, it doesn't support uploading of files.  I don't have any time at present to add this, but will gladly accept a PR if you have time and inclination to add it?  Unfortunately with it being Java it is overly verbose given the simplicity of the CKAN API :(
