Ontology: include author attributes

[akleinau]

Description of the issue

The class author should get properties:

• institution
• working field
• active time period

Ideas of solution

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

@akleinau This comes from the factsheets, too, right? So I add the 1.1 milestone

[akleinau]

not every author needs to have an institution, right? So I wouldn't state this in the ontology but when it's needed everything exists to relate an author to an institution (_author_individual_ 'has institution' value _institution_individual_).

@stap-m, @l-emele which working fields are needed or is a generic working field class enough?

active time period can be implemented by a "has active time period" relation with a one-dimensional temporal region as range.

I am not sure if _has institution_ can relate an author to an institution. According to the definition of _has institution_ it can only relate publications to institutions and according to the definition of its superproperty _has participant_ it can only relate processes and continuants (which is weird because publications are not processes). So we probably need to change both definitions to include authors as well. Another option would be to create a new object property like _member of_.

[akleinau]

member of is more generic, so I would propose to just delete has institution and create member of as a property independent of has participant

[akleinau]

ok I was too fast, has institution is still needed to relate a publication to an institution. But member of is still helpful, as well as it's inverse has member.
So:

• create has member, member of: "a relation between a person and an organisation in which the person is a member of the organisation" (adapted a bit of course depending on the relation)
• move has institution and the other not fitting relations away from has participant

[sfluegel05]

active time period can be implemented by a "has active time period" relation with a one-dimensional temporal region as range.

For active time period, maybe we could use time step, see #538

Where do we put working fields? Could they be sectors?

[l-emele]

For which purpose do we need active time period and working field? Do we intend to store such information on the OEP?

I don't think so. Also, these attributes are (constantly) changing. I'd propose to leave them out.

[stap-m]

Then it's basically the implementation of _member of/ has mamber_.

[sfluegel05]

All right. I'll do that.
