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 www.ngda.org 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.

Research
  

Welcome to the Alexandria Digitial Library Project (ADL). The goal of this project is to develop a globally distributed georeferenced digital library. Project research focuses on the following:

ADL Gazetteer

  A placename to location service supporting a complex feature-type thesaurus.

Digital Earth

  Design, implementation, and evaluation of real-time 3D interfaces for visualizing ADL geospatial digital library content.

Digital Learning Environments

  Development of an integrated learning environment based on ADL geospatial digital library technology. Currently used to teach Physical Geography to undergraduate students at University of California, Santa Barbara.

Digital Library Architecture

  Development of distributed, peer-to-peer digital library architectures and production-ready software components supporting organization, publication, discovery, and use of georeferenced documents and geospatial and other types of strongly structured scientific data.

Evaluation

  Investigation of technology-supported learning, focusing primarily on the classroom use of ADEPT by examining its impact on student learning and teaching behavior.

Knowledge Organization Systems

  Formalization of the structure and services of Knowledge Organization Systems and integration of KOS into digital libraries. Work includes gazetteer development, thesaurus development, protocols for access to distributed KOS, KOS as components of digital learning environments, and incorporating free-standing KOS into Digital Library services.

Textual Geospatial Integration

  Investigation of methods of deriving georeferencing by placenames and references to places from text (for example, 5 miles south of Abilene). Work also includes methods of deriving the geospatial placement of these references through spatial analysis.
