85. 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)

90. Benefits
• Linking to the world
• Increased “International visibility”,

• Many journals are picked up by major
abstract databases

91. Benefits
• Quality, reliability, and trustworthiness in
the discovery of Korean medical research
information
• Strong bonds among KAMJE journals
• Many new journals to join KAMJE

95. Challenges
95

96. 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

97
97

98. 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
98
98

99. 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”?
