Funding for the development of the Alexandria Digital Library middleware and the ADEPT Virtual Learning Environment, under the NSF DLI2 initiative, has now ended. Future support for enhancement and dissemination of the operational library infrastructure will be provided by the Davidson Library UCSB. ADL technology will be the starting point for designing a distributed geospatial library network funded by the Library of Congress Digital Preservation Initiative. Please see for more information.

The educational evaluation component of the DLI2 project continued into 2005, and further work on the ADEPT software and its broader deployment are under way via a joint U.S. (NSF) and U.K. (JISC) funded project: DialogPlus - Digital Libraries in Support of Innovative Approaches to Learning and Teaching in Geography.

Virtual Learning Environment

The Virtual Learning Environment provides an integrated learning environment based on digital library technology. Learning materials are explicitly organized, accessed, and presented in a way that shows objective scientific concepts and their interrelationships. The Virtual Learning Environment lets the teacher create, use, and re-use learning materials in different fields of science and in various learning environments, including classroom, laboratory, and self-guided environments. The Virtual Learning Environment is being developed as part of the Alexandria Digital Earth Prototype (ADEPT) and is currently being used to teach Physical Geography to undergraduate students at University of California, Santa Barbara.

Virtual Learning Environment Tools

We've developed the following suite of software tools to make it easy to catalog your digital assets, create concepts, and build structured lectures.

  • Cataloging Tools - create textual and geospatial item-level metadata about library objects
  • Concept System - creates concepts and relationships between concepts in a knowledge base, and displays the concepts graphically
  • Lecture Composer - creates structured lectures using concepts from the knowledge base and objects from the Alexandria Digital Library
