[okfn-be] Request use cases - feedback - tool in development

Mon Feb 19 11:00:59 UTC 2018

Hi Maxime,

For connecting the data package community with the Linked Data 
community, there happened some discussion recently on the Datahub.io 
gitter: https://gitter.im/datahubio/chat

Looks interesting in each case!

Kind regards,

Pieter
