Context Engine · semantic layer
Every line names and measures things its own way. The semantic layer gives each signal one meaning and one unit, set once, so alarms, charts, dashboards and reports agree.
What it solves
Here is what it does.
TodayLine 4 came from another vendor. Its numbers cannot sit next to the others, and every alarm needs a second set of limits.
With a meaningSay once what the signal is. From then on every chart, alarm and reader gets °C. The device never changes.
Todayproduct_temp, ProductTemp, and a third tag in the blending hall. Nobody can ask for every product temperature.
With a meaningGive them one meaning in one step, whatever each tag is called. New look-alikes are suggested, and a person decides.
TodaySix pumps on three lines means six alarms to keep in step.
With a meaningSet the limit once on the meaning. Before you save it, see how often it would have fired.
TodayA transmitter freezes and keeps sending its last value, marked good. The PLC never notices.
With a meaningA meaning knows how a real signal behaves. A value that stops moving is flagged in plain words, with what usually causes it.
TodayDashboards, scripts and reports each convert Line 4 themselves, each a little differently.
With a meaningMQTT readers and the REST API receive the converted value with its unit attached. Nobody converts it again.

Questions
It gives each signal in the Unified Namespace one meaning: what it measures and the unit it is shown in. Signals from different lines, named differently or sent in other units, then read as one, so alarms, charts, MQTT readers and the REST API agree.
No. The device keeps sending what it sends and every tag keeps its name. The meaning is set in MaestroHub, and the conversion happens there.
No. Start from your data: MaestroHub reads your signals, recognises what it can, and asks only where two answers are possible. One press applies it, and Undo takes it back.
Status: Live. How MaestroHub works shows how a raw tag gets its name, unit and checks today.
