policy instrument roles/qualities/functions

[l-emele]

Description of the issue

In #1545 we added economic instrument, regulatory instrument, information instrument, education instrument, voluntary agreement instrument and voluntary agreement to bring structure in the policy instruments.

However, there are instruments that fit in more than one category. E.g. the European Union Emissions Trading System can be seen both as an economic instrument (as certificates are traded) and as a regulatory instrument (as the emissions market only exists due to regulatory intervention).

Ideas of solution

Create a multihierarchy by introducing policy instrument roles/qualities/functions and convert the existing subclasses of policy instrument to equivalent classes.

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

[l-emele]

First try:

• An economic instrument quality is a quality of a policy instrument that expresses that the policy instrument has aspects of an economic instrument.
• A regulatory instrument quality is a quality of a policy instrument that expresses that the instrument has aspects of an economic instrument.
• ...

(I know, these are definition proposals are bit cyclic...)

@stap-m : any thoughts on this proposal?

[stap-m]

• An economic instrument quality is a quality of a policy instrument that expresses that the policy instrument has aspects of an economic instrument.
  • A regulatory instrument quality is a quality of a policy instrument that expresses that the instrument has aspects of an economic instrument.

I replaced "quality" with "property" for now. I hope that we can find a def that expresses, what we mean, and see, which classification fits in the next step. I also made some changes to find a clearer definition. Does this express, what we mean?

• An economic instrument property is a property of a policy instrument that promotes, amongst others, economic measures.
• A regulatory instrument property is a property of a policy instrument that promotes, amongst others, regulatory measures.
• ...

Axioms:

• 'economic instrument' EquivalentTo ('policy instrument' and 'has property' some 'economic instrument property' ...

[l-emele]

Do we have property resp. has property?

[stap-m]

No, its just a placeholder for now...

[l-emele]

No, its just a placeholder for now...

Do you have any proposals instead of quality? Or any argument why it is not a quality?

I also made some changes to find a clearer definition. Does this express, what we mean?

• An economic instrument property is a property of a policy instrument that promotes, amongst others, economic measures.
  • A regulatory instrument property is a property of a policy instrument that promotes, amongst others, regulatory measures.
• ...

Axioms:

• 'economic instrument' EquivalentTo ('policy instrument' and 'has property' some 'economic instrument property' ...

I am fine with this structure.
