Calculated values and alignments

[lecoqlibre]

Currently, our ontology does not store the total price of an Order. Applications need to compute that value by themselves by summing the price of each OrderLine.

I was wondering how can we align with ontologies that do provide a total price property for an Order. Are there some mechanisms to express the logic to compute the total price so the aligned ontology can fill its total price property?

Do we have any examples of ontologies that currently calculate this, for a definition?

As a first stab I'd guess: sum OrderLines and any Price associated with DeliveryOption,

I think we've discussed this before but I can't recall... where do we hold Taxes? 🤔

Actually, the Order has the property hasPrice too, so it is possible to have this value. However, it could be a problem if this value is different of the calculation of orderline_price*discount. I'm not aware of numeric calculation directly implemented in the ontology as possible, but maybe it is possible. However, the question is do we have to manage this calculation or let the ontology users do it themselves ?

@Alcoz Is there a way to align a calculated property from an ontology A to a non-calculated property from a ontology B?
