Problems in musicindustry.owl

  • CQ2: The end time is missing.
  • CQ3: roles are not time-indexed, they are asserted through specific properties, e.g. bassPlayerOf
  • CS4: missing name property for persons, Anthony Kiedis is using the property for bands and is inferred to be a band. Also missing the contextual statement that implies cardinality restrictions on people and bands, on the hasName property.
  • Ontology is inconsistent because the domain of releaseDate is the intersection of Album and Track instead of the union.
  • A track realising "some" song doesn't mean only one!
  • Definition of PopBand should be "equivalent class" instead of subclass restriction
  • The second reasoning requirement is missing, hence we cannot infer the genre of an album - can be done with an OWL 2 property chain.
  • Some missing domains and ranges, missing annotations etc.
