7. 2015 highlights
• Orcid round trip implemented
• Fundref funder IDs (registry) being auto inserted
• Deposit support for relations between DOIs
• Conflict simplification (greatly reducing the numbers)
• Interface for retrieving matched references
• Pilot roll-out of book co-access / auto multiple-resolution
(same book hosted multiple places)
• Deposit fee changes
• Moved search & rest-api operations into production
• Ongoing infrastructure improvements

8. Orcid round trip
publisher crossref author@orcid author@email

Article: ABC
Work ABC and any
other works for this
author posted to their
record.

9. Orcid round trip
As of November 10th
• 9,800 authors have granted permission (338 were short term)
• 11,784 works have been pushed to author records
• 539,018 orcid/article pairs
• 272,209 distinct articles
• 20,103 authors have not yet responded to our permission request
• 96 authors have denied permission

10. Orcid round trip
Best practice: Validate the author’s Orcid when the manuscript is submitted
Helps prevent sending permission requests to the wrong person

11. Orcid round trip
Bad practice:
Be careful !

16. Getting back your matched references
https://doi.crossref.org/getResolvedRefs?doi=10.1103/PhysRevE.91.062714&usr=&pwd=

17. Book co-access
• Reduces the coordination
necessary when the same
content is hosted in multiple
places.
• Preserves the metadata
integrity of each party’s DOI

18. Deposit fee change
Lower fee for very high volume book or data DOIs
(must be deposited within a single quarter)

19. Ongoing infrastructure management
• In 2016, provision adequate resources to support current
and new services for the next 2-3 years
• Continually re-architect towards a more robust/scalable
model
• Consider alternative options
• Ensure adequate staff & coverage
