2021-06-03 20:22:48 +0200 asked a question Orion Context Broker in production environments

Hello,

Is there a recommendation when using Orion Context Broker in a production environment (even if this production is on small scale): using Docker containers or installing the software?

Thanks. Guy

Hello,

I have an architectural question regarding data exchange between external organisations and mine.

I was thinking of subscribing to the partner organisations Orion context brokers and instead of directly storing the data from their CBs into my DB, first publish the partner messages to our CB and then store them in my DB?

E.g. advantages of the latter approach - I stil have the digital twin (last situation) what I don't have when storing directly in the DB. - Same approach for treating internal IoT devices data as well as for external data - All contextual data in the CB (also the external data)

Does this makes sense (I mean the approach passing via the CB for partner data)?

Thanks. Guy

2020-05-08 11:55:58 +0200 asked a question DeviceModel - Device

"A DeviceModel captures the static properties of a Device." Can I interpret that a DeviceModel is a "class" of Devices: meaning I can have several Devices ("instances") with the same DeviceModel: DeviceModel 1 -> N Device?

Or is there a 1:1 relationship between DeviceModel and Device?

Thanks.

Hi,

What is the manner to model a gateway device to which several end devices are connected?

My idea was: For the Gateway: DeviceModel -> category -> network All End devices: Device -> refDeviceModel (the above defined DeviceModel)

Is this correct?

Thanks.

2019-12-03 12:06:57 +0200 asked a question IoT Agent - HTTP & MQTT command (southbound)

Hello,

To me it's not clear if a device needs to take the initiative (pull) to get southbound/commands from the IoT Agent (http transport) or the IoT Agent takes the initiative (push) to the device?

For MQTT I suppose the IoT agent subscribes to the MQTT (Mosquitto) broker and subscribes and/or publishes to the MQTT broker?

Thanks for the clarification.

2019-10-21 09:09:13 +0200 asked a question Context Broker and Geo Location Visualization

What is the best approach for visualizing geo location data (e.g. polyline, polygon layers geo data in a leaflet app) with Context Broker: get the data directly from context broker or using something like geoserver between context broker and the data visualization?

Thanks.
