Identification of conflicting metadata values. Sequences from the same isolate should have identical value for certain metadata properties, such as origin. However, inconsistencies often occur, as shown in 7A. Rule-based metadata restructuring transfers the inconsistent values to the IsolateRecord resource, as shown in 7B. Since origin is declared as a functional property, an OWL reasoner can identify the inconsistency as a breach of the ontology DL constraint.
