Common questions
FAQ
Can one resource have both?+
Rarely — usually it's one or the other. A dataset attached to a Crossref-DOI'd article might appear in both metadata records but holds a single canonical DOI.
Which should I use for my software?+
DataCite (via Zenodo or Software Heritage). Crossref DOIs for software exist but are rare.
Do they share metadata?+
Yes — both expose metadata via the Public Data API; many tools (OpenAlex, Scholia) aggregate across both.
