BagIt Profile for SWORDBagIt

[richard-jones]

Can we do a formal bagit profile for swordbagit?

https://github.com/bagit-profiles/bagit-profiles-specification

We should also be clear in the spec that bag-info.txt isn't required, and that the repository won't necessarily unpack any useful metadata from it. We are not attempting to use bag-info.txt as a metadata format, only for completeness.

[richard-jones]

• add a BagIt Profile JSON document

• reference the profile document in 21.3

• add extra info about not transferring metadata in bag-info.txt
