  1. The Advanced Distributed Learning Initiative and the Handle System William H Blackmon, PhD Chief Technical Officer Advanced Distributed Learning Initiative

  2. The Department of Defense spends billions of dollars on training every year. • Types of training: • Microsoft Word basics • Aircraft maintenance • Intelligence things we can’t talk about • There is a long history of using computers to produce effective training

  3. ADL was established in 1997 to increase the effectiveness of training in the DoD • ADL tackled the problem of self-paced, managed learning • Created SCORM, which establishes a baseline for creating and delivering training • A SCORM course is a zip file containing everything needed for a Learning Management System to run the course • SCORM has been widely successful in the DoD, corporate, K12, and higher-ed sectors

  4. Nearly identical training content is developed by different groups because: • “I didn’t know they were developing content” • “Their training doesn’t exactly meet my needs” • “Their training doesn’t match my look and feel” • “I have to guarantee the accuracy of the content” • “There’s no financial incentive to me” • “It’s easier to develop new content than to find and adapt old content”

  5. The ADL-Registry is a central website for the DoD • To register the existence of SCORM content • To search for existing content • Using a metadata schema acceptable to the community • Military culture dictated that the content remain under “local control” • So the ADL-Registry points to the content

  6. The ADL-Registry uses Handles • As the GUIDs for the content • As a way to manage persistent IDs for content in a world with ever-changing URLs • To manage authorization rights for users of the registry

  7. But we see more interesting uses for Handles in our near future!

  8. Multiple Resolution • Using a single Handle to name a training resource, how do I find the content on: • SIPR net • NIPR net • Internet • Disconnected Submarines? • We need hdl:2000/1 encodings to work instead of relying on http://hdl.handle.net • We need an automatic resolution system

  9. Versioned Content • The DoD depends on authenticated content • When content is updated, we need to: • Keep the Handle to old content active • Tell users the content has been updated • Tell users where the new content is • Let the users decide which content is right for their needs • hdl:2000/1?version=latest • hdl:2000/1?availableversions

  10. Handles in Content Packages • A course table of contents could look like this: • Local context-setting learning object • hdl:2000/2 (shared learning object) • hdl:1890/4 (shared learning obejct) • Local summary learning object
