@alivedise  you mean which part ? `initRegisteredKeywords` is just a handy function that it will fetch out keywords registered in manifest can automatically register them in iac_handler and will emit related event back to the function who catch iac-* events. Can you tell more ?

Because In your comment , you mentioned that each IAC consumer have to do *something* but in my implementation, IAC consumer *dont* have to do anything. 

Are we talking about the same thing ?
