oh…
• Ran
into
trouble
with
each
agency
– BHL
isn’t
a
publisher
– BHL
is
a
consor)um,
not
a

– BHL
doesn’t
own
all
the

it
serves
– “We

8. Challenge:
Ownership
of
Backfiles
• Who
owns
public
domain
works?
– Some
publishers
consider
they
have
ownership
of
backfiles
for
journals
they
currently
publish
• Long
running
series
in
natural
history
• Cur$s’s
Botanical
Magazine,
since
1787
• Those
publishers
assign
DOIs
to
their
current
volumes
• BHL
assigns
DOIs
to
the
public
domain
works
we’ve
digi)zed

15. I
also
asked
CrossRef
support
• Turns
out
it’s
a
bug!
• CrossRef
DOI
API
wasn’t
returning
results
for
ISBN-‐less
books
– And
remember,
we
don’t
have
those
because
of
the
ugly
problems
• We
iden)fied
&
resolved
a
problem
via
Twiqer!
– Crowdsourcing
#FTW!
@cajunjoel
– Talk
about
#lod
bringing
people
together!
@asaletourneau
• And
all
because
of

16. And
then
a
dash
of
reality
@rdmpage
• “…why
bother
with
linked
data?
Obviously
I
know
the
stock
answer,
but
the
reality
is
that
most
"linked
data"
isn't
linked.…CrossRef
RDF
for
an
ar)cle
the
only
external
link
(eventually)
is
to
hqp://
periodicals.dataincubator.org/
via
the
ISSN.
Author
names
have
arbitrary,
non-‐resolvable
URIs.
So
effec)vely
the
data
is
a
silo.
Linked
data,
yes,
RDF,
yes,
but
s)ll
a
silo.”

17. Takeaway
• Assigning
modern
iden)fiers
to
legacy
content
is
challenging
– “We
know
we
need
a
policy
on
that…”
– Benefits
are
there,
but
may
be
slow
to
realize
• Working
with
an
agency
like
CrossRef
has
its
advantages
– Support
– Tech
advances:
they
flip
a
switch,
instaLOD
– Disadvantages:
Co$t,
may
s)ll
need
custom
solu)ons
for
emerging
technologies
• Linked
Data
is
conceptually
promising,
but
fraught
with
uncertainty
in
produc)on
systems
