Why DOI?

• CrossRef: Since 1999 has issued 78,722,137+ DOIs on behalf of scholarly and professional Journal publishers.
• DataCite: Founded in London on 1 December 2009 to support methods to locate, identify and cite data and other research objects and has issued 7,220,204+ DOIs.
• What a DOI does: These two agencies issue DOIs on request to a publisher and in exchange receive Metadata back from the publisher about the item.
• In 2015, together with ORCID, the two organisations started to co-operate, allowing:
  • Auto-population of metadata from CrossRef and DataCite into ORCID Record
  • Researcher DataCite profiles specifying metadata harvesting
  • Exchange of metadata connecting Journal articles ⇔ data/other research objects
  • and hence future rich searches of this superset
• The infrastructure underpins CRIS Systems (Current Research Information Systems)
