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

Hi Maxime!

Sounds interesting! Some related work to that is from university of 
Vienna: http://data.wu.ac.at/odgraph/ → They extract geo-semantic labels 
from Open Datasets and create a search interface across this.

Next, do you convert your dataset to Linked Data and then export it to 
the data package format? Because the latter really applies to non Linked 
Data. For what exactly is this useful?

Finally, is there some code we can look into, or some dataset that was 
the end result of your process?

Looking forward to meeting you at Open Belgium 2018!
