Based upon Bill Ingram request:

This is how file-level deposits into DSpace look like:

https://seadtest.ideals.illinois.edu/handle/123456789/563
https://seadtest.ideals.illinois.edu/handle/123456789/565
https://seadtest.ideals.illinois.edu/handle/123456789/564

The idea was that each of the parts could have their own detailed metadata, rather than a single metadata set for the whole. That use case doesn't seem to hold up, at least not with this test data.

Need to consider pros and cons of file-level and collection-level deposit.
