#initialize(attributes_or_id = nil) {|_self| ... } ⇒ Object

Constructor. You may supply a custom :id, or we call the Fedora Rest API for the next available Fedora id, and mark as new object. Also, if attrs does not contain :id but does contain :namespace it will pass the :namespace value to Fedora::Repository.nextid to generate the next id available within the given namespace.

Yields:

  • (_self)
