What it is

Relationships from Crossref DOIs to DOIs from other registration agencies (including DataCite) and Crossref metadata records of type dataset. The data is supplied by Crossref members.

What it does

Where members include references to datasets and DOIs from registration agencies other tha Crossref, the Crossref Event Data agent creates an event.

Where data comes from

Metadata registered by Crossref members. The data is retrieved from the Crossref REST API. Both the reference and relation fields are checked.

Example Event

Methodology

  1. A member makes an XML deposit with Crossref containing references or relationships.
  2. The Agent monitors new deposits (or back-fills).
  3. When a link is found an Event is created if:
    • it is to a non-Crossref DOI
    • it is to a Crossref DOI record of type dataset
    • 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

DOIs must be included in the reference (in a structured or unstructured form).

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.
