Great news for me to see such a nice solution based on Python and OData version 4.0! So good when "our" standards are being followed by the implementers so closely. There are still some OData v2 and v3 solutions out there not yet being upgraded to v4. Note: OData v4.0 is now also an ISO standard (unchanged from the OASIS version including applied errata): 20802-1:2016(E) "Core" and 20802-2:2016(E) "OData JSON Format". Thanks a lot for presenting to Ken and for implementing to David and the developers! One nit: The article still has a placeholder "", I think.
