Consistent-but-all-unsat Uli Sattler An ontology that is consistent, but all named classes are unsatisfiable. Ideas by Alan Ruttenberg
One equals two Alan Ruttenberg Start with 3 classes, a,b,c and relate them so instances have to be in a 1:1 relationship with each other.

The class b-and-c is the union of b and c. Therefore there have to be 2 instances of b-and-c for every instance of a.

Relate the class 2a to b-and-c so that *their* instances are in 1:1 relationship.

Now relate 2a to a so that *their* instances are in a 1:1 relationship. This should lead to a situation in which every instance of 2a is 1:1 with an instance of a, and at the same time 2:1 with an instance of a.

Unless all the classes have an infinite number of members or are empty this doesn't work. This example has a is the enumerated class {i,j,k} (i,j,k all different individuals). So it should be inconsistent.

For two triples with the same inverse functional data property as their predicates and with the same data object, the subjects are the same. This test shows that the OWL 2 RDF-Based Semantics allows for IFDPs.

TestCase:WebOnt-FunctionalProperty-003 Jeremy J. Carroll If prop is an owl:FunctionalProperty, then its inverse is an owl:InverseFunctionalProperty.
TestCase:WebOnt-I5.1-001 Dan Connolly stateCode example using an inverseFunctionalProperty and literals
TestCase:WebOnt-I5.1-010 Jeremy J. Carroll There are 128 different bytes that are also unsigned integers; and hence also 127.
TestCase:WebOnt-InverseFunctionalProperty-002 Jeremy J. Carroll If prop belongs to owl:InverseFunctionalProperty,

and object denotes a resource which is the object of two prop triples, then the subjects of these triples have the same denotation. Hence any assertion made

using one of them can be transferred to the other.
