---|---|---|

Datatype-restrictions-different-types | Birte Glimm | The individual a must have dp fillers that are in the sets {3, 4} and {2, 3} (different types are used, but shorts and ints are integers). Furthermore, the dp filler must be 3, but since 3 is in both sets, the ontology is consistent. |

Owlreal-plus-oneOf | Birte Glimm | The individual a must have either negative Infinity or 0 (-0 as integer is 0) as dp fillers and all dp successors must be from owl:real, which excludes negative infinity, but allows 0. |

Consistent-dataproperty-disjointness | Birte Glimm | The datatype properties dp1 and dp2 are disjoint, but the individual a can have 10 as a filler for dp1 and 18 as filler for dp2, which satisfies the disjointness. |

Consistent-dateTime | Birte Glimm | The datatype restrictions leave exactly one dateTime value as dp filler for the individual a, so the ontology is consistent. |

Consistent-integer-filler | Birte Glimm | The individual a is in the extension of the class A, which implies that it has a hasAge filler of 18 as integer, which is consistent with the all values from integer assertion for a. |

Inconsistent-pattern-disjointness | Birte Glimm | The data properties dp1 and dp2 are disjoint. The strings ab and ac are dp1 fillers for the individual a and can, thus, not be used as dp2 fillers for a. The pattern a(b|c), however, admits only ab and ac as values, which makes the ontology inconsistent. |

Qualified-cardinality-restricted-int | Evren Sirin | The cardinality restriction states there are exactly 3 dp values where the allowed values should be greater than or equal to 1 and less then or equal to 3. Obviously there are only 3 such values so we can conclude that the individual a should have dp values 1, 2, and 3. |
