Meta: roles vs single-Person contexts

[saerdnaer]

Not a problem of this ontology itself, but probably an frequently asked question when modelling organisations:

One has to decide how reusable the role definitions should be for example when you want to model the coffee machine operations, you have two options:

• A) define a "coffee machine" context with includes the service aka the coffee pouring devices and the persons maintaining these. You can also modell interactions with external context like the company you got the maschines from, or which delivers your coffee beans etc.
• B) You define a new role "coffee machine maintainer" in the parent context
