[okfn-help] CKAN questions...

Mon Jul 7 13:04:01 BST 2008

Hi Jonathan, Hi Rufus,

Thanks for doing the system updates so quickly. I'm taking it easy today 
cos I did a fair amount of work on CKAN/datapkg over the weekend. :-) 
Got lots done, still one of two niggles though (esp.: tags are breaking 
the datapkg ckanregister command and its causing a 500 error; the recent 
changes log entries are blank; etc.).

Thanks!

Not immediately at the moment. But is this something you will want to do?

(It would be quite easy to use the ckanclient to get the list of 
packages, then get each package, and count packages per tag.)

Not very readily at the moment. But is this something you will want to do?

If these are valuable stories (not my call!) we can plan to develop 
support for them. The second one will take a bit more chewing than the 
first.

Great. :-) Have a nice day.

Best wishes,
