Add something like service product or non-material good

[l-emele]

Description of the issue

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. Services are associated with some very abstract "results" that have the added value of the service, this could be something like a service product or a non-material good.

Ideas of solution

If you already have ideas for the solution describe them here

Workflow checklist

• I discussed the issue with someone else than me before working on a solution
• I already read the latest version of the workflow for this repository
• The goal of this ontology is clear to me

I am aware that

• every entry in the ontology should have a definition
• classes should arise from concepts rather than from words

My proposal is to handle this similar to how good is implemented, we define 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, 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 fine with this proposal.

@stap-m @nelekoehler @fabianneuhaus any second opinions before I implement?

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.
I added the word "process" to the definition to underline the difference between service and service product.
