JSON to JSON-LD Creator App

hi Everyone

>From the past few days I was pondering over the implementation of a JSON to
JSON-LD Creator app and unfortunately I wasn't able to think anything
concrete.
I would like to thank Dave Longley to provide me a better understanding of
the problem in question and help me achieve it :)

So foremost, my question was how to deal with JSON (thinking of his
vastness and diversity) and followed it was how would I be in a position to
understand and make sense out of it so that the JSON-LD is actually not a
misleading one!

The following solution (to my understanding is awesome :-)) is provided by
Dave during the course of brainstorming! A simple Form-based structure app
which will have basic input fields Like Name, Age, etc and have other
fields that can be added to it using dropdowns or other mechanism. This way
I will be able to get a well defined JSON and will help me in developing
the creator app. I loved this idea also for the reason because it scrapes
the possibility of generating garbage JSON-LD.

I plan to rely upon @vocab of Schema.org.

Adding to thing, Dave suggested to go with AngularJS over Backbone and use
an MVC :) [and I have started digging this]

I would really love if the community could provide me with some more inputs
over this so I could start the implementation of this phase :-)
