Every number the collector samples becomes a sensor with a stable dotted ID (cpu.core.3.usage, fan.nct6775.fan2, fs.root.used_pct). Clients discover them from the catalog and ask for exactly what they want, including as a shaped query: send the object you want, get it back with the values filled in.
