Hello Ant,

our department is about to adapt CKAN for managing our research data, 
and metadata seems to be the main obstacle. We are considering to write 
a similar feature as you have developed. So, yes, we would also be 
interested to look at your code. It would be great if we could get this 
turned into a standard extension.

Thanks a lot for sharing.

Best wishes,
Felix
