OpenPub : Cards

Everything in OpenPub is represented as a card. Cards define their own arbitrary structure and can be combined and composed.

Each type of card is comprised of several fields which can store certain ranges of values (see below).

A value of null implies that the network is free to select a default value if one isn’t specified.

{
  "type": "Example",
  "help": "http://format.example.com/openpub/version/1",
  "version": 1,
  "revision": 1
