Detailed Description

The object carousel is transmitted as a directed graph. The leaves are files and the intermediate nodes are directories. A directory can contain references to files or to other directories. Certain directories, known as gateways, are special and represent roots of the graph i.e. they are not themselves referred to by other directories. One of these gateways is referenced by a DownloadServerInitiate message and is the root for the particular carousel. Crucially, directories and files may be shared between directories and gateways. For example, the BBC radio channels Radio 1, Radio 2, Radio 3 and Radio 4 all share the same object carousel and differ only in the DownloadServerInitiate message.
