The brackets < > are not part of the identifier itself.

To identify a born-digital or a digitised object in the managed digital collections of the National Library of Australia, an intelligent identifier has been constructed which utilises a sub-namespace to encode the collection type and, based on the type, rules for accessing component parts of the object.
