[Fiware-espoo] FW: Espo connection to FI-Lab

[Toivanen Timo]

Hi Fermin,

Thank you for the response. I have some additional questions as we are developing our Espoo connection to the Fi-Ware.


-          Is there any development instance of Orion Context Broker that we could use during the development phase? Or should create our own Context Broker instance to FI-Lab?

-          Is any context provider registration needed or is there any authentication requirement when using the Fi-ware Orion Context Broker?

-          Can we query historical data from the Context Broker? Or should query history data from Cosmos Big data? If so, does Context Broker automatically forward data to Cosmos?

Cheers,
Timo

Hi,

Sergio passed this question to me. I'm the one in charge of Orion Context Broker in FI-WARE.

The updateContext payload you send is mostly fine. However, take into account the following comments:

  *   Remove the attributes xsi:type, xmlns:xs and xmlns:xsi in contextValue tags. Orion doesn't pay any attention to them.
  *   First time you send updateContext for a new entity (in this case entity ID 101005 of type weatherStation) you need to use APPEND as actionType in order to "create" the entity at Orion. Next updateContext requests (once the entity has been created) should use UPDATE (although APPEND is also allowed in that case: an APPEND actionType on existing context elements in interpreted as UPDATE).

I hope this information helps...
Best regards,

Hi all,

As planned, we are developing context provider to send messages to FI-Lab. I started with weather data and I’m creating NGSI updateContextRequest-messages for measurements made by Finnish Meteorological Institute. The measurements are provided in every 10 minutes and they include several different parameters like temperature, wind and precipitation.

Here’s an example message, do you have any comments about it? How should I add station location and measurement timestamp information? Should they be included in their own contextAttribute-elements?

BR,
Timo

Hi,

In addition to update DoW-document description we made a short document about what data sources will be connected to FI-LAB. We have not yet fixed the showcase application.

Best Regards,

Timo
