Permissions are used to publish attributes of components to the just:play and just:live user interface. In simple words this means you can specify which attributes of a component will be modifiable in the Inspector of just:play/just:live, for example the text of a lower third. This ensures that you can dynamically change the displayed content of a graphic template.
