The idea is to have the notion of a 'resource' that is being edited. This isn't a hard rule,
but generally most edit patterns follow this structure. Anything custom can be easily made
to be different.

Let's say I have the notion of a 'prospect' in the system that I can modify. The number of
attributes it has are unimportant at the moment, it's more about the high-level logical
resource that is being modified. Using REST-based resource routing, most frameworks
would give you something like this (this is Rails-based, but others are similar):

  endpoint        | verb   | controller file              | action (function to be executed)
