IIIF: Access to the World's Images / 7 Dec 2015
mark@dp.la / @anarchivist / @dpla
DPLA as cultural heritage
aggregator
● 11 million+ items aggregated from US
libraries, archives, and museums
● 27+ “Hubs” (primary partners)
● 1,600+ contributing institutions
DPLA partner breakdown
DPLA: more than an aggregation
● Over 21 million hits over 6 months;
57% traffic via portal; 43% through API
● Support development of open,
community sustaining work
● Facilitate re-use of collections, software,
and standards
● Amplify our own efforts, as well as those
of communities that are like-minded
Motivations for DPLA network
adoption of IIIF
● Promotion and support for open
standards
● Improving usability
● Lowering bar for image delivery and
reuse both within and outside DPLA
● Supporting annotation on and across
cultural heritage resources
Evaluating user experience of
delivering images
● Unclear pathways to access objects
● Too many clicks to get to content
● Various image viewers lead to interface
inconsistency across providers
● Not only true for portal users, but API
users as well!
Impacts on developers using the
DPLA API
DPLA Hubs with IIIF
implementations
● Production: image & presentation APIs
○ Harvard University Library
○ Internet Archive (beta)
● Production: image API only
○ California Digital Library (Calisphere beta)
○ Digital Commonwealth/Boston Public Library
● Under development
○ ARTstor
○ David Rumsey Map Collection
Implementation issues for DPLA
● Representation of IIIF resources in
EDM/DPLA Metadata Application Profile
● Metadata about IIIF images not available
from harvest sources
● UX consistency for IIIF/non-IIIF images
● Impact of IIIF on Hubs’ use statistics;
guidance on analytics
● Uncertainty about provision of IIIF
services
Next steps for a DPLA pilot …?
● Resolve modeling issues with EDM
maintainers and IIIF editors
● Ensure IIIF resources are identifiable in
metadata, either through harvesting or
creating URIs from available identifier(s)
● Prototype, prototype, prototype!
Thanks!
