KAMJE’s DOI history

• What is it? (2005)came across “DOI” in literature

• Many discussions, workshops with KAMJE member journal editors

• Visited JST (2007.5)• 1st DOI prefixes assigned (2007.6.28)• DOI submission test, 1 article (2007.11.28)• 1st DOI submissions, 25 articles

(2007.11.29)

Benefits

9090

• Linking to the world• Increased “International visibility”,

“Discoverability”and “Retrievability”• Many journals are picked up by major

abstract databases

Benefits

9191

Benefits

• Quality, reliability, and trustworthiness in the discovery of Korean medical research information

• Strong bonds among KAMJE journals• Many new journals to join KAMJE

Challenges

9696

Challenges

• DOI Resolution errors – DOI conflicts/Wrong DOIs/Workflow control

• Full text XML to CrossRef DOI deposit XML -XML converters

• DOI deposit submission queues– At the end/beginning of a month, 1-3 days

sitting in the queue– The problem seems gone after the DOI

submission system transition in October 2012

DOI resolutions and error rates

• DOI resolutions % share increased• Error rates decreased

9898

Challenges

• Persuading societies to use DOI• Communicate with societies what to

do and what to not do• Back issues–Most societies will begin putting DOIs for

current and on-going articles– Sometimes for the last 1 or 2 years– But not for the last 5 or 10 years– Only a few journals from the 1st issue

9999

DOIs for back issues

• Limited budgets• No Born digital files

can not easily OCR• Keying in “References” all over again?• Will be very nice if “Cited-by linking” is

available to back issues• Would it be o.k. to apply “cited-by

linking” to articles with no “reference linking”?

Concluding Remarks

106106

What CrossRef Services are you participating in?

• Reference Linking• CitedBy Linking• CrossCheck• CrossMark• CrossRef Metadata Services

107107

To what types of content are you assigning CrossRef DOIs? How many of each?

• Journal articles• Data• Figures, Tables• Supplementary materials• Journal titles• Books (3)• Proceedings titles• Proceedings papers Components• Reports, theses

108108

Concluding Remarks

• KAMJE plays an important role as an Open Access publisher for Korean medical journals to promote and facilitate– Global distribution of Korean medical

research information– International visibility, discoverability

and retrieavability

109109

Concluding Remarks

• KAMJE’s recent activities (especially database related activities) are very much focused on keeping up with international collaborative efforts by adapting international norms and standards in publishing and database industry.

• DOIs and other CrossRef services have been and are very effective means to achieve these goals.
