Good morning everyone,
I hope you guys had a great Easter holiday.
We would like to ask you for a consolidated feedback on our suggested
Fiware implementation.
Florian sent an email on March 27th and José confirmed the setup on the
same day. Florian also had a call with the Knowage team to get their
advice and during the call our setup was confirmed.
Now Davide wrote another mail on March 29th saying that he sees some
issues with the Knowage implementation. However it doesn't really
contain a concrete advice what we can improve.
Therefore we'd be very happy if you could confirm the setup as soon as
possible or otherwise provide detailed specification what you expect so
that we can present a proper solution on Friday.
Thanks a lot in advance and have a great week!
Best regards
Martin

Replied by email to martin.bruecher@fashion.cloud, florian.klemt@fashion.cloud, josemanuel.cantera@fiware.org, juanjose.hierro@fiware.org, Alessandro.Portosa@eng.it:
Dear Martin
your proposed implementation seems fine, except the part with Orion Context Broker, Knowage and MySQL.
As already stated, you can use MySQL and Knowage for hystorical analyses, not for real-time analyses. If you want to display real-time data coming from the Orion Context Broker, you have to retrieve data directly from Orion Context Broker by a NGSI dataset in Knowage (Florian should know how to do that, in any case documentation is here: https://knowage.readthedocs.io/en/latest/user/NGSI/README/index.html) and display it into a Knowage cockpit.
My concern I tried to explain to you in my last email was about the usage of the Orion Context Broker: there was only 1 entity defined! therefore I thought it was a poor usage and your application not "context-aware".
The more your application can get meaningful information from real-time data, the more your application is "context-aware"; therefore I suggested Florian to define many more entities in the Orion Context Broker and to exploit them properly (displaying it in Knowage or implementing some business logic).
Hope this helps
Best regards
Davide
