Our catalog is organised hierarchically into “collections”, “items”, and “files”. A depositor can have any number of collections, each of which contains one or more items, and each item in turn contains one or more files.
Items contain files and there can be no duplicate item names. Related files can have the same name, for example an .eaf file would have the same name as the media item and both are stored inside an item,
e.g. ITEM EG1-Fred has the file ‘Fred20150108’ so its name then is EG1-Fred-Fred20150108.wav and its transcript is EG1-Fred-Fred20150108.eaf. The description is at the level of EG1-Fred.
You don’t need to list filenames in the metadata. Only item names and the files need to be named correctly so they are associated when uploaded.
