3. What
cita)on
offers
• To
aid
scien)fic
reproducibility
• To
provide
fair
credit
• To
ensure
scien)fic
transparency
&
accountability
• To
aid
in
tracking
the
impact,
including
– helping
data
authors
verify
use
of
their
data
– helping
future
data
users
iden)fy
how
others
have
used

8. What
is
an
iden)fier?
What
you
see:
alphanumeric
string
(never
changes)
Associated
with:
loca)on
of
object
(such
as
a
URL)
OpDonal:
who,
what,
when,
etc
(i.e.
metadata)

12. Create
&
manage
persistent
identifiers
and
associated
metadata
• Allows
precise
identification
of
a
dataset
• Allows
credit
for
data
producers
and
data
publishers
• Provides
a
link
from
the
traditional
literature
to
the
data
• Potential
for
research
metrics
for
datasets
Example:
Sidlauskas,
B.
2007.
Data
from:
Tes)ng
for
unequal
rates
of
morphological
diversifica)on
in
the
absence
of
a
detailed
phylogeny:
a
case
study
from
characiform
fishes.

19. DOIs
and
ARKs
Both:
• Work
like
regular
hyperlinks
• Refer
to
a
subset
or
por)on
of
a
resource
• Become
persistent
when
the
target
URL
is
maintained
