License Signed

Emitted when an author (or an authorised signer on their behalf) signs a licence for a publication. Alongside the signing details — who signed, when, and which licence applies — the payload carries a shared manuscript-context block (publication and manuscript identity, journal, corresponding author, and any institutional agreement) so the event can be reconciled against a manuscript without a separate lookup.

dateSubmitted	string (ISO 8601 date-time, UTC) or null	Timestamp at which the manuscript was submitted. null when not recorded.
dateAccepted	string (ISO 8601 date-time, UTC) or null	Timestamp at which the manuscript was accepted. null when not recorded.
dateArticleWithdrawn	string (ISO 8601 date-time, UTC) or null	Timestamp at which the article was withdrawn, if applicable. null for a normal signed licence.
institutionalAgreementName	string	Name of the institutional agreement that applies to the publication (for example, Italy CARE-CRUI Agreement, Research 4 Life - AL, German Academic Consortium Discount). Empty string when no agreement applied.

licenseId	string	Identifier of the licence record in ChronosHub. Stable and suitable for use as a foreign key on the partner side.

Notes

• All timestamps are serialised as ISO 8601 strings.
• The manuscript context block (identity, journal, corresponding author, and institutional agreement) is shared with the Invoice Paid event, so a partner can build or reconcile a manuscript record from either post-acceptance milestone.
• Nullable date fields (dateSubmitted, dateAccepted, dateArticleWithdrawn, agreementDate, dateLicenseSelected) are emitted as null when no value is recorded. String fields default to an empty string rather than null.
• The corresponding-author fields describe the first listed corresponding author and their primary affiliation.
• This payload describes the event data only — not the transport-level envelope (event id, event type, signature headers, and so on).
