[ckan-discuss] Difficulty deleting resources

[Brian Lee Yung Rowe]

Adria,

Thanks so much for the guidance. I looked at the ckanapi project, and it doesn't seem to include the file upload capabilities of ckanclient. Is the idea that ckanapi will replace ckanclient or should I consider them to serve different purposes?

Many Thanks,
Brian
