WoT Runtime, Scripting, Bindings Zoltan Kis, Intel

WoT Runtime WoT RT Script 1 Things Things Process view ● WoT RT: one process ● Bindings: separate processes TDs ● System APIs / OS Kernel Script n System APIs ● Socket → protocol stack Scripting API (client, server, discovery) (CoAP/UDP, BLE, etc) ● file system Things ● secure storage manager ● local sensors. Runtime implementation (process) System Scripting access Use the Scripting API to ● Interact with remote Things ● ...and services (e.g. fetch TD) plugin iface plugin iface plugin iface ● Access System APIs, via Protocol Protocol System Thing + bindings) system binding binding ● Manage Things (create, delete, run, stop, …), via ManagerThing + bindings System API
