Hydra repository framework

• A framework for building digital library applications

• Robust and scalable: Building on Fedora Commons object repository

• Fast web application development using Ruby on Rails

• Accessible/interoperable: RESTful web service API to all data operations (CRUD)

• State of the art search and retrieval: Solr & Blacklight

• Mature and active community: space for more European partners!

We use it for…

• Support of all stages of object lifecycle

• Deposit/curation/preservation planning• Digital object archival• Dissemination (web and API)

• Support of all digital object types• Minimal set of common metadata• Generic discovery layer

(Solr/Blacklight)• Generic repository (Fedora Commons)• Specialized dissemination applications

(Hydra)• Interface to bit archival repository• Cooperation, code sharing and reuse of other Hydra users’ application gems (”lego bricks”)
