A new concept for Sector Activity

0UmfHxcvx5J7JoaOhFSs5mncnisTJJ6q commented 3 years ago

Description of the issue

This originates from OEO Dev Meeting 24. We do have different sectors as entities in the ontology (e.g. the energy transformation sector and the industry sector), but do not have a concept/class describing the sectors' activity. This is needed to annotate energy use and emissions (as activity subclasses) of sectors.

Workflow checklist

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

I am aware that

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

If I remember yesterday's discussion correctly we need to describe the following two general concepts which are applicable to all sectors:

In a sector occurs some energy consumption and this has to be quantified with some energy amount value,
In a sector occurs some (greenhouse gas) emission and this has to be quantified with some emission value.

My spontaneous idea is to introduce the following two classes:

sectoral energy consumption: A sectoral energy consumption is the consumption of energy of a sector. (Axiom: 'has quantity value' some 'energy amount value')
sectoral emission: A sectoral emission is the emission of a sector. (Axiom: 'has quantity value' some 'emission value')

With these classes, post-composition outside the OEO for the specific subclasses like energy transformation sector and industry sector should be possible. But we can also include pre-composed subclasses in the OEO.

Anyway, some relations would be helpful. Something like consumes and emits which connect the sectors with sectoral energy consumption and sectoral emission. I think participates in (a relation between a continuant and a process, in which the continuant is somehow involved in the process) is a suitable parent relation. Such new relations are not limited to the use cases of this issue but can e.g. also be used to describe the connection of artificial objects like power plants to the respective energy consumption and emission.

I tried to find definitions, but I don't think these would fit perfectly. But maybe it helps a bit to move on. First ideas for definitions: consumes: A relation between a continuant and a consumption, in which the consumption quantity value of the continuant is somehow increased by the consumption. emits: A relation between a continuant and an emission, in which the emission quantity value of the continuant is somehow increased by the emission.

Relations like consumes / emits should rather relate to a continuant than a process. An axiom like industry sector emits some greenhouse gas makes sense. For the relation to the processes, we could create smth like "causes" or "induces": e.g. industry sector causes some sectoral emission (process)

In #582 we decided to use has part to connect emission to other processes. For some classes we have already implemented this; one example is the axiom fuel-powered electricity generation has part some emission.
