[transferred from OEO] Add terms regarding the load of vehicles

[lumi321]

Description of the issue

Add some terms for the number of passengers/amount of goods in a vehicle including a maximum capacity.

Ideas of solution

• vehicle load: A vehicle load is a quantity value indicating the magnitude of the load (passengers or goods) of a vehicle.

  • passenger load: A passenger load is a vehicle load that results from passengers.
    • passengers per vehicle: Passengers per vehicle is a passenger load averaged over a number of vehicles.
  • freight load: A freight load is a vehicle load that results from freight.
    • freight per vehicle: Freight per vehicle is a freight load averaged over a number of vehicles.

• vehicle capacity: A vehicle capacity is a maximum value that indicates the maximum load of a vehicle.

For the units I suggest:
'passenger load' 'has unit' some ('mass unit' or 'count unit')
'freight load' 'has unit' some ('mass unit')
'vehicle capacity' 'has unit' some ('mass unit' or 'count unit')

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

This issue is a bit beyond the scope of the OEO, but it might be something for the planned transport ontology (working name "Open Transport and Trade Ontology", OTTO).

I transfer this issue to the OTO repo 🥳
