Use Case: Given a DOI, directly download & verify an RO-Crate

As a researcher (or aggregation service), when given a DataCite DOI, I'd like to be able to directly download & verify (e.g. by comparing checksums) an RO-Crate so that I can (for example) use it in a downstream workflow without having to parse the DOI landing page

Realizing this use case is beyond scope of this spec, but it should inform the spec and guidelines, so that RO-Crate can satisfy this use-case for third-parties. For discussion/examples of the need for direct download from a Persistent Identifier see:

• Freya Project Use-Case
• RDA PID Kernel Information Working Group
• MINIDs linked to BDBags

I have been giving it a thought, about a practical way to do it. If the DOI landing page of a dataset can contain schema.org annotations, a way to automate the discovery of the download links for automated systems could be through an specific annotation containing it, which should be agreed by the different actors.
