Topic Structure
- User-defined topics in the form of tenant/obsType/custom/topic/parts
- Tenant and observation type explicitly required in all topic
- Topics created as activityCreator are only for configuration purposes and are saved in DB
- They are used in reasoners configuration inside activity
- They do not include tenant in their name (creator topics in the form of /amtech/things/eventsources/<topic>/<levels>)
- Topics created as follower or as part of the execution of an activity are not persistd in DB. They are mqtt topics to hold observations
- System topics in the form of prefix/tenant (ex. topic for OTA, for new digital twin, etc.)
- Core topics
- Commands : _cmd/<tenant>/<thingtype>/<thingid>/<user-defined>/<path>
- Crud : <tenant>/observationresourcecrud/<thingType>/<thingId>/<crudOp>
- Bridge crud: _bridge/<tenant>/observationresourcecrud/amtechM2mBridge/<bridgeId>/_all/<propId>
