Consumes Artifacts	none
Matches by	DOI

Coverage	All DOIs
Relevant concepts	External Agents, Occurred-at vs collected-at
Operated by	DataCite

When members of DataCite deposit datasets, they can include links to Crossref Registered Content via their Crossref DOIs. The DataCite agent monitors these links and sends them to Event Data. As this is an External Agent, there are no Artifacts or Evidence Records.

Example Event

{
  "obj_id":"https://doi.org/10.1007/S10518-016-9982-8",

  "message_action":"create",

}

Methodology

• DataCite operate an Agent that scans its Metadata API for new citations to Crossref DOIs. When it finds links, it deposits them.
• It can also scan for back-files

Notes

• Because the Agent can scan for back-files, it is possible that duplicate Events may be re-created. See Duplicate Data.
• Because the Agent can scan for back-files, Events may be created with occurred_at in the past. See Occurred-at vs collected-at.
