Fedora
• Flexible Extensible Digital Object Repository
Architecture
• Mellon-funded development at Cornell and UVA
• Now under the stewardship of Fedora Commons and
DuraSpace
• Architecture defines a set of abstractions for expressing
digital objects, inter-object relationships, and
behaviors/services
• Software provides core functionalities
– Web-based services w/APIs
– Searching support and OAI-PMH exposure
– Preservation metadata creation and extraction

Fedora Digital Object Model:
Architectural View
(From presentation: Sandy Payette, March 19, 2003, ISTEC Symposium, Brazil)
Persistent ID ( PID )
Globally unique persistent id
Disseminators
Public view: access methods for
obtaining “disseminations” of digital
object content
System Metadata
Internal view: metadata necessary to
manage the object
Datastreams
Protected view: content that
makes up the “basis” of the object

Fez Object Managements:
Metadata and XSDs
Any metadata schema
can be mapped and
referenced in Fez using
references between XSDs
Using Fez XSDs and
forms, metadata
can be updated in
Fedora Objects
XSDs supporting
Search Key
mappings, as well
as OAI exposure
