Owl:equivalentClass

  

Note: The use of  does not imply class equality. Class equality means that the classes have the same intensional meaning (denote the same concept). In the example above, the concept of "President of the US" is related to, but not equal to the concept of the principal resident of a certain estate. Real class equality can only be expressed with the owl:sameAs construct. As this requires treating classes as individuals, class equality can only be expressed in OWL Full.

Note: Because this is a OWL Full Standard we may not support this Syntax for garanteed computability.
