Disjoint means that a given resource cannot have the same value for ex; property as for ex:property2. E.g., a pref label for resource X can’t be the same as alLabel for resource X. Is this what you meant? Or do you mean something else i.e., it either have a value for ex:property or a value for ex:property2 e.g., either foaf:givenName or foaf:firstName, but not both. If so, then use xone: https://www.w3.org/TR/shacl/#XoneConstraintComponent > > 2. Inferring data: Suppose ex:property and ex:property2 are disjoint for a > given shape, as specified above.
