Fedora architecture

• Extensible framework for the storage, management
  and dissemination of complex objects
• Allows you to create, manage, publish, share and
  preserve digital content
• Includes a Resource Description Framework
  (RDF)-based relationship model ( a RDF
  triplestore)
• Service Oriented Architecture (SOA)
• Versioning support
