IIIF is a set of open standards for delivering high-quality, attributed digital objects online at scale. Once installed (see installations notes) it can be configured in the admin area at the IIIF tab.
Be aware that
IIIF is optional for an OpenAtlas installation
Although already working and in use we still consider it experimental
Enabling it can expose used files to the public (without login)
IIIF - Select this checkbox to enable IIIF
URL - Set the complete URL to the Image API Server, e.g. https://yourserver.eu/iiif/
Version - The manifest version provided by OpenAtlas. Currently only version 2 is available.
Path - Set the absolute path to the IIIF image drop zone which corresponds with the Image API Server folder, e.g. /var/www/iipsrv/ if you followed the default OpenAtlas installation. Be aware that this folder has to be accessible (write and execute) for the webserver.
Conversion - Controls if images get converted into pyramid-TIFFs
none - no conversion
deflate - lossless but files size may be large
jpeg - much smaller files size but not lossless
In case you are running multiple OpenAtlas instances you should create a sub directory for every instance at /var/www/iipsrv/ and also add these to URL and Path accordingly.
These formats have been successfully tested with OpenAtlas:
