19. Future
work:
• Improved
annotation
tools
(e.g.
with
typed
links)
• Annotating
additional
types
of
objects
• Publish
open
data
for
DH
researchers
Challenges:
• Limited
resources
• Developers
not
familiar
with
Linked
Data
• [
Data
modelling
]

20. Linked
Digital
Collection
“Rainis and
Aspazija”
• Rich
collection,
various
types
of
content
• Object
annotations
– additional
links
between
objects
• Linked
Data
interface
– publishes
open
data
(for
reuse)
– links
to
objects
in
other
Linked
Data
systems
