add service product #1584

[viktorwichern]

Summary of the discussion

Discussions (e.g. in #1487 and #1239) have shown that we sometimes have to aggregate good and service which is difficult as good is a continuant and service is an occurent.

For this reason, we decided to add a continuant that expresses the value of a service.
We decided on a similar solution to how good is implemented and added a role and an equivalent class.

service product role
definition: A service product role is the role of an immaterial entity that is the result of a service process, and whose value is determined by the value and the costs of the service.

service product
definition: A service product is an immaterial entity that has the service product role.

I am wondering, if oeo-shared is the right place. good lives there, but service is in oeo-social. Since we try to maintain the modular stucture, for which we did the restructuring after all, I am tending to suggest oeo-social here, too. @l-emele any opinion?

PR should be good to go, do you want to wait for an answer?

I agree that these should be in oeo-social.
