As a final note - CVEI is a convention for which order to pick for a typical task.
The advantage of using these particular orders isn't as much functional as it is conventional. In fact, the order you assign is just an integer value.
import pyblish.apiclass MyValidator(pyblish.api.ContextPlugin):order = pyblish.api.ValidatorOrder # == 1
The benefits of sticking with CVEI are two-fold.
The ordering provides a common language with which to discuss publishing.
And under the hood, they allow Pyblish to make assumptions about your plug-ins, such as when to abort.
This language fuels our community, and the assumptions are what fuels the mechanics of Pyblish.
With this in mind, saving plug-ins are typically named after what they are.
