In this specific case I think the production of a function object of type EXTERNAL COATING and its identity is overkillvvagr wrote:This parameter will resolve the problem, but I can not see it in the model. More then that, such third role is completely unnecessary. In templates existential quantifier (or Scolem variable) is used to hide exactly this type of unnecessary data items. Why do we return them into patterns?
This may be appropriate for a plant maintenance system where the coating is subject to inspection repair etc but if
all we are concerned about is the color and/or specification of the coating this can be handled by simple classification
using members of ClassOfClass PROTECTIVE COATING CLASS
In the real world you normally maintain a coating specification for the piping and equipment items
on the project and point to that specn. In ISO 15926 terms this truly is a CLASS rather than
an individual.
Typical Standards include:
EN 10288 Steel Tubes and Fittings for Onshore and Offshore Pipelines - External
Two Layer Extruded Polyethlene Based Coatings
EN 10289 Steel Tubes and Fittings for Onshore and Offshore Pipelines - External
Liquid Applied Epoxy and Epoxy-Modified Coatings
EN 10290 Steel Tubes and Fittings for Onshore and Offshore Pipelines External
Liquid Applied Polyurethane and Polyurethane-Modified Coatings
