A few follow up notes:

Save link doesn't work. Right now it just logs all the 'db' data in the console. I'm thinking I'll need to implement a back-end to be able to save the updated pages, but totally open to suggestions.

Kinda cool.

But I'm not sure I understand the reasoning for this though.

Essentially, you've created a way to parse and query objects using an object structure to hold them? so json.

Then I assume you are storing this in localStorage or something similar?

If you are going to go down the back end route though you'd surely just opt to be using mongoDB no?

All good points - I'm not sure about the practicality of it, just intrigued by the ability to store and retrieve data from HTML elements.

I can't imagine at the moment any project where it would be used, but who knows, maybe someone would, or maybe not. Mainly just seeing what it possible to create and then seeing if there are any ideas to help take it away.
