Items with multiple digitizations
Subitems represent a digitization of part of a real world object, such as a page of a book, or a scan of one side of a document. You will need to submit metadata for both the top level item (the document) and for each subitem that represents an individual page or image of that document, for example.
Please follow these guidelines when structuring metadata for items with multiple digitizations:
- Each subitem should be submitted in a separate row
- All subitems and the top level item should share the same unique item id
- For the parent item, set the
filetypetosequenceand leave thefilespecempty - The rows for subitems should specify a unique
subitemid, meaning that it should not be repeated under the corresponding top level item - The rows for subitems should also specify an
orderidwith an integer (1,2,3...) denoting the order of subitems within the top level item
