The following content model diagram is for an item in Avalon 6, with an example video recording provided from Northwestern University's instance of Avalon. Avalon began development using Fedora 3 and has transitioned to Fedora 4 for its content model but does not use PCDM for identifying its object types. Ordering of sections within a single Avalon item is managed using the optional ordering recommendation from PCDM through proxy objects. IndirectContainers connect MediaObjects to MastFiles so that the same MasterFile can be used in multiple MediaObjects. Derivative files for access and playback are not stored in Fedora but are served from an external streaming server.
