Islandora is an open-source software framework designed to help institutions and organizations and their audiences collaboratively manage, and discover digital assets using a best-practices framework. Islandora was originally developed by the University of Prince Edward Island's Robertson Library, but is now implemented and contributed to by an ever-growing international community.
Built on a base of Drupal, Fedora, and Solr, Islandora releases solution packs which empower users to work with data types (such as image, video, and pdf) and knowledge domains (such as Chemistry and the Digital Humanities). Solution packs also often provide integration with additional viewers, editors, and data processing applications.
Islandora operates under a GNU license.
For information about Islandora integration with Fedora 4, please check out the CLAW project.
