What is Pacific Lighthouse?• A research collaboration between UW,
CENIC, providers of digital collections, and school partners
• An on-demand media repository built upon MediaWeb technology, I2 middleware, and the high-performance advanced services networks in California and Washington
• An investigation into the pedagogical uses of digital libraries

Goals of Pacific Lighthouse• To evaluate the performance of Internet2
technologies (e.g., MediaWeb), and identify issues associated with use
• To determine how teachers and students might use digital collections as primary source materials
• To assess the usefulness of multi-media digital collections for pedagogical purposes

Parallel Project
• Pacific Lighthouse is a complementary project to Viewing the Future, a video repository aligned with Michigan educational standards that is being created by a partnership between UW and MERIT
![Page 14: An On-Demand Media Repository](https://reader035.fdocuments.us/reader035/viewer/2022062800/5681407f550346895dac047a/html5/thumbnails/14.jpg)
Scaling Up
• By means of the SEGP structure, the National Internet2 K-20 initiative will leverage both Pacific Lighthouse and Viewing the Future to provide access to a wide variety of on-demand media first to additional states, and then to the national K-20 community
