OriginalThe unified namespace, explained
One broker, one topic tree, every producer and consumer decoupled. What a UNS is, what it demands, and where it goes wrong.
MQTT
MQTT messaging for telemetry, UNS architectures, and device connectivity.
OriginalSparkplug B in one page
The topic namespace, birth certificates, and state awareness that turn MQTT from a transport into a plug-and-play OT data fabric.

The three MQTT features that decide whether your telemetry is lossy, stale, or exactly-once — and when each setting is correct.
Protocol conversion, buffering, and context at the edge — the four gateway patterns that connect legacy equipment to modern platforms.
