CRUD promises
From AMTech WikiDocs
Most operations in the DAP are executed through promises. It means that they are queued for execution and the real execution occurs asynchronously. This is the case of CREATEs, UPDATEs and DELETEs of things coming from the Activity's Execution Engine. In case of errors in the execution of queued promises, this error is reported through the sensors_network topic in the form of an observation.
