I.e.
    has-occupation(person: joe-cocker, occupation: plumper)
    has-occupation(person: joe-cocker, occupation: composer)
    has-occupation(person: joe-cocker, day-job: musician)

It depends how you define "has-occupation" if it is defined as "has
knowledge about it", the 1st association does need a scope, if it's
defined as "works as", the 1st association should maybe have a scope
which represents a period of time.

Best regards,
Lars
