Hydra is an ecosystem of components that lets institutions deploy robust and durable digital repositories (the body) supporting multiple “heads”: highly feature-rich digital asset management applications and tailored workflows. Its principal platforms are the Fedora Repository, Blacklight, Solr, and Ruby on Rails.
ActiveFedora- Built on RubyFedora, this ruby gem provides an active record oriented way of working with objects in Fedora
ESciDoc - An eResearch environment developed specifically for use by scientific and scholarly communities.
The Fascinator - A front end to Fedora commons repository that uses Solr to handle all browsing, searching, and security.
Hydra - Will provide a "Lego Set" of web services and templates that can be used for a wide range of content management workflows. (Not released yet but coming soon.)
Islandora - A Drupal module that allows users to view and manage objects stored in Fedora.
RODA - An OAIS-compliant, service-oriented digital repository system designed to preserve government authentic digital objects.
eSciDoc is as a joint project of the Max Planck Society and FIZ Karlsruhe, funded by the Federal Ministry of Education and Research (BMBF), aimed at building an e-research platform for multi-disciplinary research organizations.
Islandora is an open source project underway at the Robertson Library at the University of Prince Edward Island. Islandora combines the Drupal and Fedora software applications to create a robust digital asset management system that can be used for any requirement where collaboration and digital data stewardship, for the short and long term, are critical.
