ADS shares those matches with us via its API, and we use that information to populate DOI and JREF fields on arXiv papers.
I've always wondered if this were true. I continue to wonder if arXiv uses other sources of eprint-DOI matches to corroborate or append to those from ADS.
if cross-format identifiers like DOIs are used, annotations made in one format (eg, EPUB) can be seen in the same document published in other formats (eg, HTML, PDF) and in other locations.
Whaa..? This sounds seriously hard. But remarkably clever.
The proxy service (both doi.org and the earlier but no longer preferred dx.doi.org)
Hypothesis now uses DOIs to join variants of the same document in the same way it uses PDF fingerprints. Both pieces of metadata — the DOI, and the PDF URL — are typically included in HTML metadata.
This is really cool! Thanks for the great explanation!

Each item added to the repository will be assigned a DOI, which means you can trust they will be persistently resolvable. In our exemplar role, we will ultimately be connecting the DOI to the creator’ ORCID iDs
