Editorial commentary

Work assertions can be self-claimed by the iD holder, auto-fetched via search-and-link wizards (Crossref, DataCite, Scopus, Europe PMC), or pushed by trusted-organisation members through the Member API. Each assertion carries a ‘source’ field identifying who made the claim; the same work can have multiple sources and ORCID groups them by external identifier. The CRediT contributor-role taxonomy may be encoded in the assertion when available.
