13. DINI Issues on a
Global Scale?
• BASE as the global source for Open Access
items
• An Open Access repository is not a matter of
size but a matter of content!

20. • small Data Base (268k) • large Data Base (36m)
• Metadata • Metadata
• 5% unknown Languages • 34% unknown Languages
• 11% unknown Doctypes • 61% unknown Doctypes
• 30% unknown DDC • 92% unknown DDC
DINI Certificate makes Sense!

27. Have the really grown?
y
• OAN shows the importance of DINI and
the DINI Certificate in Germany

issues in Germany have to be tackled

28. Bottom line:
„Some (repositories have grown,
)
others ne more support than ever
ed
to catch up
