Hi Steve,

There is a well document External Term Format protocol. I am not here to judge that protocol but it is implementable on other languages as well (https://github.com/rustyio/BERT-JS). Yes, it make sense in scopes of that protocol specification. 

Long time ago, I've been trying to use it for WebApp development and … switched to JSON. :-)
But I strongly believe that External Term Format make sense for other use-case...


Best Regards,
Dmitry
