> +Question:+
> FIWARE IoT Agent Framework: How to define a device with nested attributes in IoT Agent e.g geo:json?
> +Description:+
> I can't find how to define a device where its entity contains nested attributes.
> The need is to pass gps coordinates from a device to an entity having geo:json (like urn:ngsi-ld:Shelf:unit001 in tutorial https://github.com/FIWARE/tutorials.Entity-Relationships)
> Following the https://fiware-tutorials.readthedocs.io/en/latest/iot-over-mqtt/index.html the below
> curl -iX POST \
>   'http://localhost:4041/iot/devices' \
> ...
>   -d '{
>  "devices": [
>    {
>      "device_id":   "motion001",
>      "entity_name": "urn:ngsi-ld:Motion:001",
>        { "object_id": "c", "name": "count", "type": "Integer" }

>                 }
>             }
>         },
> How to replace the count above in order to get the below outcome ?
>             "type": "geo:json",

>                 "coordinates": [13.3986,52.5547]
>             },
> In all examples and documentation the attributes are defined in one level (not nested)  https://iotagent-node-lib.readthedocs.io/en/latest/api/index.html.
