9: * Allows to convert values between arbitrary types.
10: * <p>
11: * The main intended use is for annotation property mapping to attributes of type {@link Object}, which can hold both
12: * literal values and references to other individuals. In that case, the loaded instance is a {@link NamedResource} and
13: * needs to be transformed to a {@link java.net.URI} to prevent the internal OntoDriver API from leaking into the
14: * application.
15: * <p>
16: * Similarly, OntoDriver API's {@link LangString} is transformed to {@link MultilingualString}.
17: * <p>
18: * In all other cases, the values will be just returned without any conversion.
