Topic Design for Automotive Use Cases

Publish datasets mentioned above can follow this topic pattern.

<TenantID>/<AppId>/vehicles/<VIN>/tx/data/<dataType>
<TenantID>/<AppId>/vehicles/<VIN>/tx/geohash/<geohash>
<TenantID>/<AppId>/vehicles/<VIN>/tx/event/<eventType>
<TenantID>/<AppId>/vehicles/<VIN>/tx/command/<commandType>
Eg.
(BMW/telemetry/vehicles/ABCDEF/tx/data/json)
(BMW/v2x/vehicles/ABCDEF/tx/geohash/pqrs/t/u/v/BSM/binary)

Subscribe datasets mentioned above can follow this topic pattern.

<TenantID>/<ApplicationId>/vehicles/<VIN>/rx/data/<dataType>
<TenantID>/<ApplicationId>/vehicles/<VIN>/rx/geohash/<geohash>
<TenantID>/<ApplicationId>/vehicles/<VIN>/rx/event/<eventType>
Eg.
(BMW/telemetry/vehicles/ABCDEF/rx/data/geohash/pqrs/t/#)(BMW/telemetry/vehicles/ABCDEF/rx/command/door/open)
