Quick API demo
Five Events from Crossref source:
https://api.eventdata.crossref.org/v1/events?rows=5&source=crossref
What it is
Relationships from Crossref DOIs to DataCite DOIs. The data is supplied in the metadata of Crossref's Registered Content by Crossref members who are the 'owners' of the Registered Content.
What it does
Where members include DataCite DOIs in references the Crossref Event Data agent establishes the relationship between the DataCite DOI and the Crossref DOI as an event.
Where data comes from
Metadata registered with Crossref that references a DataCite DOI. For other Crossref member metadata, you can find it in the Crossref Metadata REST API.

Methodology
- A member makes an XML deposit with Crossref.
- The agent monitors new deposits (or back-fills).
- When a link is found an Event is created if:
- it is to a non-Crossref DOI
- it has not already been reported to Event Data
Evidence Record
No evidence record is created because the events come straight from the data source into Event Data.
Edits / Deletion
We do not anticipate that Events are ever deleted or edited.
Quirks
None.
Failure modes
- Member may remove references before the Agent first scans the data, in which case we will not create a new Event
- Member may deposit incorrect metadata.
