Description

The Product that has been ordered (1 and only 1)

Definition

• Predicate: dfc-b:concerns
• Range: string (literal)
• Inverse: concerned_by
• Cardinality: Single-valued on OrderLine — the ontology restricts those classes to exactly one value. On that class the property is a scalar; elsewhere it may be a collection, because the ontology is silent.

Notes

• Declared on 2 class(es) in the ontology, but inherited by 2. The connectors place a slot on every root class when its domain names no schema class, so it is available everywhere.
• The schema records no required or multivalued flag for this slot.
