The schema for Gistbook entities.
View gistook.md

A Gistbook is a JSON file. Individuals are encouraged to build applications that render the Gistbook format in a variety of ways. One example of this is Gistbook.io, which happens to be linked to Github Gists for convenience.

Gistbook

title: The name of the Gistbook
author: The author
updatedAt: The datetime that the Gistbook was last updated as an ISO8601 string
createdAt: The datetime that the Gistbook was created as an ISO8601 string
pages: An array of Pages
resources: URIs to external resources that are necessary to render the Gistbook

toJSON is bad for serializing stuff.
View to-json-shim.js
/*
* toJSON Shim
* Marionette 1.8.7 uses toJSON to serialize the model data for views,
* which goes against the specifications of Backbone. toJSON should be
* used for serializing your data back into JSON, primarily for the purposes
* of returning it back to the server. Views should include their own version
* of toJSON for display purposes.
*
* This is an open PR on Marionette and will be merged soon.
