Optional jsonld: anyOptional options: IManifestoOptionsreturns the PropertyValue which in turn allows a language-specific string encoded in the json as the "label" property
var label = manifest.getLabel().getValue(); // returns the string for default locale
var label = manifest.getLabel().getValue(locale); // locale a string , examples
// would be "fr", "en-US",
A function that wraps the getProperty function, which client code can use if it is needed to identify when the json value of a property is an IRI -- Internationalized Resource Identifier
If the value of the json value is a bare string, then it will be wrapped in a json object with the string in the property 'id', additionally that property will have a property 'isIRI' which will be true for the literal string case, otherwise false meaning the returned getProperty should be parsed as before.
With the 3D extensions to the IIIF Presentation API the name of this class is misleading, but for now is being retained for the sake backward compatibility with earlier manifesto code and tests.
The 3D extensions allow that the body property of an annotation can be a light, camera, or model, or a SpecificResource object wrapping a light, camera, or model. *
