This profile is derived from the profile of a real collection: http://bindings.lib.ua.edu/
This collection consists of approximately 5400 book cover objects, which are stored in Fedora using an atomistic model: the parent object contains descriptive and administrative metadata about the book, and the child objects contain images (one image per child) and technical metadata about the image.
For the sake of simplicity, I've flattened the collection into compound objects: every object contains both the descriptive and administrative metadata, and the image content streams and technical metadata. I've left out the METS structmap, RELS-EXT, RELS-INT, and DC datastreams, to give a picture of the content.
| Parameter | Suggested values | Notes |
|---|---|---|
| Number of objects | 6000 | |
| Average number of datastreams per object | see note | 1 - 4 binary TIFF datastream: average is 1 -4 XML MIX technical metadata streams, one for each image: average is 1 MODS datastream 1 PREMIS datastream Total average: |
| Standard deviation of datastreams per object | see note | TIFF datastreams: XML MIX datastreams: |
| Average size of datastream | see note | TIFF: MODS: MIX: PREMIS: |
| Standard deviation of datastream size | see note | TIFF: MODS: MIX: PREMIS: |
| Average number of properties per node | n/a | no properties set |
| Standard deviation of properties per node | n/a | |
| Is datastream data random? | Yes | Each datastream is unique; there are no constant value datastreams. |
