Presentation Transcript

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

  2. 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 • Concept: • 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 • CORDRA Team • ADL Program: CORDRA vision, advocacy, and resourcing • CNRI: CORDRA development • DTIC: CORDRA operation

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

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

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