Property equivalence
In metadata, property equivalence is the statement that two properties have the same property extension or values. This usually implies that the two properties have the same semantics or meaning. Technically it only implies that the data elements have the same values.
Property equivalence is one of the three ways that a metadata registry can store equivalence mappings to other metadata registries.
Note that property equivalence is not the same as property equality. Equivalent properties have the same "values", but may have different intensional meaning. Property equality should be expressed with the owl:sameAs construct. As this requires that properties are treated as individuals, such axioms are only allowed in OWL Full.
