CORDRA: Content Object Repository Discovery and Registration/Resolution Architecture

CORDRA (Content Object Repository Discovery and Registration/Resolution Architecture): An open, standards-based model for how to design and implement software systems for the purposes of discovery, sharing and reuse of learning content through the establishment of interoperable federations of learning content repositories.

CORDRA is designed to be an enabling model to bridge the worlds of learning content management and delivery, and content repositories and digital libraries. CORDRA aims to identify and specify (not develop) appropriate technologies and existing interoperability standards that can be combined into a reference model used to enable a learning content infrastructure.

CORDRA is:

A formal model that can be used to design federations of repositories (the CORDRA reference model).
A collection of operational systems built from the CORDRA model, including:
- a prototype implementation of a repository federation; and
- an operational federation of federations used to combined different CORDRA federations.
The activities and projects surrounding the definition of the CORDRA model and creation of the operational systems.

The CORDRA activities are being coordinated by the Advanced Distributed Learning Initiative, (ADL) the Corporation for National Research Initiatives, (CNRI) and the Learning Systems Architecture Lab (LSAL).
