The International Image Interoperability Framework community
(http://iiif.io/) is pleased to announce the release of the second major
version of its specifications intended to provide a shared layer for
dynamic interactions with images and the structure of the collections
and objects of which they are part. These APIs are used in production
systems to enable cross-institutional integration of content, via mix
and match of best of class front end applications and servers.
This release adds additional functionality derived from real world use
cases needed by partners within the community, and reflects more than a
year of experience with the previous versions and significant input from
across the cultural heritage community. It also formalizes many of the
aspects that were implicit in the initial versions and makes puts into
place a manageable framework for sustainable future development.
Detailed change notes are available.
The specifications are available at:
Image API: http://iiif.io/api/image/2.0/
Presentation API: http://iiif.io/api/presentation/2.0/
Accompanying the release of the specifications is a suite of community
infrastructure tools, including reference implementations of all
versions of the Image API, collections of valid and intentionally
invalid example Presentation API resource descriptions, plus validators
for both APIs. Production ready software is available for the full Image
API stack, with server implementations in both Loris  and IIP Server
, and rich client support in the popular Open Seadragon .
There will be a rollout and dissemination event on October 20th, 2014 at
the British Library to celebrate this release and engage with the wider
community. Further details at http://iiif.io/event/2014/london.html, all
are welcome but (free) registration is required.
