Old Release

This documentation covers an old version of Fedora. Looking for another version? See all documentation.

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.
