Museums Community Letter to Digital Asset Management (DAM) Software Vendors

Led by the IIIF Museums Community Group, with support from museums and other 
cultural heritage institutions across the globe, an open letter has been sent 
to a number of DAM software vendors encouraging the adoption of IIIF in DAM 
products. The letter is available for viewing and sharing online at

Europeana IIIF Task Force

The Europeana IIIF Task Force is working to identify the current trends and 
tendencies among Europeana content providers towards the handling of the 
emerging IIIF technology.

Technical Work
A/V Technical Specification Work

The IIIF A/V Technical Specification Group<> 
has been modeling various A/V use cases using IIIF manifests and canvases. 
Wider discussions about ranges within manifests have informed modeling work for 
both IIIF A/V and other objects with complex hierarchies. Experiments are 
currently underway to implement the current IIIF A/V 
model<>, as 
the group looks to test the model and address issues related to syncing 
multiple video and/or audio files in a single 
 The Avalon Media System team at Indiana University and Northwestern University 
has been working on a proof of concept for 
 towards a new 
release<> that 
will include an audio and video player that works with IIIF manifests. The 
group is still seeking A/V material to experiment with, unencumbered by rights 
issues that would prevent reuse, and suitable for all audiences, such as:
o    A variety of single formats in common use today (mp4, webm with common 
o    MPEG-DASH and HLS file sets (no live streaming yet though)
o    Media accompanied by common sidecar files (webvtt appears in a few 
o    No objections to anyone turning your webvtt to web annotations and also 
publishing those
o    Sets of mixed media if you have them - oral history interviews plus 
transcriptions, albums and images of their covers and inner sleeves; again 
unencumbered by rights (appreciate that might be tricky for some things)

See the A/V group page<> for details on how 
to join in the discussion and learn more.

Discovery of IIIF Resources

The IIIF Discovery Technical Specification 
Group<> is working to solidify a 
specification for the “IIIF Drag and Drop” functionality that has already been 
implemented at various institutions across the community. The group is 
currently soliciting use cases for drag and drop as well as other cases for 
importing IIIF images to viewers. Use cases may be submitted in the 
iiif-stories GitHub repo<>. The 
group has also been exploring the pros and cons of various mechanisms for 
crawling and harvesting IIIF collections and objects. To join the discussion 
and learn more, visit the IIIF Discovery group 

IIIF Text Granularity Technical Specification Group

As more institutions and vendors are working with annotations and text in the 
context of IIIF, a need has grown to specify degrees of granularity for text 
annotations (such as word, sentence, paragraph, etc.) in relation to the IIIF 
Search API<>. The IIIF Text Granularity Technical 
Specification Group has just formed to begin this work. If you are interested 
in participating in Text Granularity group discussions, please review the group 
 and indicate your interest. Stay tuned to the 
IIIF-Discuss<!forum/iiif-discuss> email list 
for more details.

OpenJPEG Improvement Project

Several institutions in the IIIF community have come together to launch the 
first phase of a collaborative effort to facilitate improvement of 
OpenJPEG<>, an open source JPEG 
2000<> codec, freely available under a BSD 
license<>. A project 
is currently underway to improve performance, scalability, security, and 
robustness of OpenJPEG, with the initial phase focused on improving decoding 
speed, region-of-interest decoding, and memory footprint. Project status can be 
tracked via GitHub<>, and more 
details can be found on the OpenJPEG 
website<>. The 
project team welcomes additional funding institutions to contribute to future 
phases and sustain the effort to bring OpenJPEG up to speed with proprietary 
implementations of the JPEG 2000 standard. To learn more and get involved, 
please contact Sheila Rabun, IIIF Community and Communications Officer, at<>. See more details at

Community Groups:

Please see the IIIF Community Groups page<> for 
a calendar of group and community calls, as well as links to more information 
about each group. All of the community groups will be meeting in person at the 
2017 IIIF Conference<> in June.

Manuscripts Community Group

In addition to making preparations for a number of manuscripts-related 
presentations and a manuscripts discussion session at the IIIF Conference, 
participants from the IIIF Manuscripts Community 
group<> have been involved in 
ongoing training and pedagogical outreach at Kalamazoo, DHSI, Rare Book School, 
Medieval Academy, and elsewhere. The manuscripts community is looking to 
coalesce on basic metadata for manuscripts that might be passed in a IIIF 
manifest, as well as looking toward discoverability hubs for manuscript 
materials and creating user-facing documentation and training materials. The 
group would like to increase collaborative efforts to move the community 
forward, particularly through integration of existing projects and repositories 
and developing advocacy lines for encouraging additional digitization efforts 
and IIIF compliance for manuscript materials.

Museums Community Group

The museums community recently sent an open letter to Digital Asset Management 
(DAM) software vendors<>, urging 
the adoption of IIIF. As interest in institutional adoption of IIIF grows in 
the museums community, the group is working on adding information to the 
general IIIF FAQ<>, including details on examples 
of museums that are already using IIIF in their digital repositories. The IIIF 
Conference in The Vatican (first week of June) will feature a museums 
track<> on 
Thursday, 8 June.

Newspapers Community Group

The IIIF Newspapers group<> 
congratulates the Bavarian State Library on their implementation of IIIF for 
 and the National Library of Wales’ recent release of IIIF-compliant 
journals<>. Interest in IIIF and text is 
growing, and the group is preparing to contribute to work on specifying text 
granularity for IIIF annotations. The community is also preparing to work with 
Boston Public Library and the University of Utah on their recently awarded IMLS 
grant<> to develop 
IIIF-compliant Hydra solutions for digitized newspapers.

Software Developers Community Group

The IIIF Software Developers group<> 
continues to work on developing and documenting IIIF client components that can 
be mixed and matched in various viewing environments. While demonstrations of 
IIIF implementations typically occur on the bi-weekly IIIF Community 
Calls<>, the Software Developers group invites 
more in-depth technical discussion of implementations, for sharing strategies 
and advice on the technical aspects of IIIF implementation in software.
