Control Groups:
a. Managed Content (M): Datastream content is stored and managed within the Fedora repository’s persistent storage. The content can be any MIME type including XML. b. Inline XML (X): A special case of M, restricted to well-formed XML. In this case the datastream content is stored as part of the XML structure of the digital object itself and is thus included when the digital object is exported (e.g., for archival purposes). c. Externally Referenced (E): Datastream content is external to the Fedora repository and is referenced by a URL that is recorded within the digital object. The content can be any MIME type including XML. d. Redirected Content (R): Like E, but datastream content is delivered to the client without any mediation by Fedora; i.e., via an HTTP redirect. You should use this datastream type when the external content is a web page with relative links or it is streaming audio or video. The content can be any MIME type including XML.
