WoT RT: one process
Bindings: separate processes
System APIs / OS Kernel

System APIs

Socket → protocol stack

(CoAP/UDP, BLE, etc)

file system
secure storage
local sensors.

Scripting Use the Scripting API to

Interact with remote Things
...and services (e.g. fetch TD)
Access System APIs, via

System Thing + bindings)

Manage Things

(create, delete, run, stop, …), via ManagerThing + bindings

WoT Runtime

network→ system/socket→ binding→ runtime→ manager/action → run script → API→ runtime (eval) → [fetch TD: system APIs→ bindings→ socket→ runtime→ API→ TD] → impl (create Things+bindings)→ manager/reply → bindings→ system/socket→ network.
