The digital collection and archives (DCA) in partnership with Academic Technology (AT) at Tufts University developed a digital library solution for long-term storage and integration of existing digital collections, such as Perseus, TUSK, Bolles and Artifact. We describe the Tufts digital library (TDL) architecture. TDL is an extensible, modular, flexible and scalable architecture that uses Fedora at its core. The extensible nature of the TDL architecture allows for seamless integration of collections that may be developed in the future, while leveraging the extensive tools that are available as part of individual digital library applications at Tufts. We describe the functionality and implementation details of the individual components of TDL. Two applications that have successfully interfaced with TDL are presented. We conclude with some remarks about the future development of TDL.

    • "Furthermore, to examine the effect of the computerized concept maps on the learners' writing, the researchers introduced VUE (Visual Understanding Environment) to the students for its ease of manipulation. The software was designed by Tufts' Academic Technology department and was commonly used in computerized concept mapping experiments (i.e., Kumar & Saigal, 2005; Kumar, Saigal, Chavez & Schwertner, 2004). Writers can create their nodes with different symbols, and display the relationship between each node with the connecting arrowed lines. "

    ABSTRACT: This study investigated tertiary level EFL university students’ attitudes toward computer based concept mappings in a six-week writing program. Based on the pretest and posttest design, twenty freshmen constructed their computer-based concept maps collaboratively. The 24-item instrument was revised from Lee's questionnaire (2010), in which the participants’ attitudes, the perceived usefulness of computer-based concept mapping were investigated, and their opinions toward collaborative concept mapping were collected on a five-point scale. Results showed that students did not have any significant attitude change toward concept mapping. However, higher rating of their perceptions toward the usefulness of computer-based concept mapping, and toward collaborative construction of concept mapping was found.

    • "Institutional repository is one of the components of knowledge management systems. It holds content-explicit knowledge and is concerned with managing, maintaining and distributing this content [3], [8], [7]. Different organizations, such as universities, public and private R&D laboratories, and business establishments , have understood the importance of information repositories and hence a number of organizations building their repositories is increasing rapidly especially in developing countries [6], [12], [4].

    ABSTRACT: Institutions increasingly recognize the need to develop digital repositories for organizing and managing their intellectual output to enhance scholarly communication. An institutional repository (IR) enhances opportunities for efficient use of existing research material and improved learning experiences, and encourages collaboration within and between different disciplines and groups. Installing IR software is not a major issue, but the challenge lies in tailoring the software and setting up services, policies, and procedures to make it work effectively in an institutional environment. The purpose of this paper is to document SEECS IR system's experience in developing the institutional repository. The contribution of this paper is to provide a case study which will be useful for other academic institutions in developing countries who want to develop their own institutional repositories.

    • "Fedora is a flexible repository system with powerful digital object model for managing institutional repository needs [1]. Fedora has become one of the popular repository systems and Tufts University has adopted it as the framework for its digital repository [2]. Some of the features, which make Fedora appealing to us include versioning, policy model, object extensibility, support for rdf, and objects relationship management. "
