How to deal with moving objects? #29

Open geoxanadu opened 6 years ago

geoxanadu commented 6 years ago

Trying to implement the SensorThingsAPI we came accross the issue of moving objects. The data model supports the location change over time (moving object). However, in the API only Observations are allowed to receive values via MQTT. If there are moving objects i.e. cars which needs a continuous update of their location we promote the possibility that this topic should also be able to updated via MQTT.

For some use cases FeaturesOfInterest can be used for tracking the location of moving objects. you can see more explanation in my response in issue #33. However, there are use cases that the Location is needed and it worth discussing adding MQTT for Locations in the next SensorThings meeting. Thanks for pointing that out.
