Advanced Distributed Learning Initiative International DOI Foundation Meeting 22 June 2004 James Erwin Defense Technical Information Center

Content Object Repository Discovery and Registration Architecture (CORDRA) Goal: Provide a lightweight, distributed capability to support the registration, discovery, access, and reuse of SCORM compliant digital learning objects n Concept: n – Loose confederation of SCORM compliant digital learning object repositories – Distributed Handle assignment; centralized namespace assignment – Centralized registration of repositories and digital learning objects – Centralized discovery and repository/object resolution n CORDRA Team – ADL Program: CORDRA vision, advocacy, and resourcing – CNRI: CORDRA development – DTIC: CORDRA operation

Shareable Course Object Reference Model (SCORM) Architecture Course Lesson Shareable Course Object (SCO) Asset

CORDRA Concept Handles and Repository/Object Metadata DTIC Repository/Object Registration Discovery Repository/Object Resolution Distributed SCORM Compliant Repositories Estimated 100 -200 repositories and 10 M digital learning objects

Content Object Repository Discovery and Registration Architecture (CORDRA) n Technology: – – – n Database: Berkeley DB Search engine: Lucerne Identification/resolution: Handles Schedule: – Operational prototype in Sep 2004 – Operational system in Dec 2004
