ItemUnicorn: The myth of federated search realized simply. Unifying DSpace repositories with the PKP Harvester tool(Georgia Institute of Technology, 2009-05-21) Davison, John ; Gilbertson, KeithThe Ohio Digital Resource Commons, located at http://drc.ohiolink.edu, is a union of DSpace repositories operated by higher education institutions in Ohio. The repositories are largely organized and supported by OhioLINK, a consortium of 89 Ohio college and university libraries. In support of the vision of the Digital Resource Commons as a statewide resource, the repository operators saw an immediate need for a federated search tool. A "build it now" approach was taken, and federated searching was implemented in a short timeframe at OhioLINK using the PKP Harvester (http://pkp.sfu.ca/?q=harvester) software. A demonstration of the federated search feature at the Digital Resource Commons will be given, highlighting local customizations that were made to PKP Harvester and DSpace in support of the project. These customizations include changes made to mimic the appearance and behavior of existing search interfaces at OhioLINK, and changes made to meet expressed user requirements. Particular attention will be given to a DSpace change that allows image thumbnails to be displayed in federated search results. Issues encountered during the configuration, implementation, and deployment of the PKP Harvester and DSpace OAI-PMH server will be presented, and the choices made in response to these issues will be explained. The process of integrating the search results with the DSpace interface will be detailed, including ongoing efforts to improve the user experience. The Digital Resource Commons' federated search was implemented as a metadata-based search. We will present a general comparison between metadata and full-text searching, highlighting the advantages and disadvantages of each method. A discussion of metadata uniformity and quality concerns will be presented in the context of federated searching. Particular problems encountered with our metadata will be described, with lessons learned and suggestions for resolution. Operational and maintenance concerns of this system will be discussed, including the metadata harvesting schedule, and the need to flush and rebuild indexes when the metadata schema changes. Future ideas for the DRC's federated search feature will be explored, including an implementation of faceted searching using SOLR, harvesting of non-DSpace repositories, such as CONTENTdm and Fedora, and, finally, the possibility of discarding the current model in favor of an OAI-ORE based system, developed for DSpace at Texas Digital Library, that allows for the possibility of full-text federated searching.

ItemEIAH's Experience in Localization and Customization of DSpace(Georgia Institute of Technology, 2009-05-21) Khazraee, Emad ; Malek, Hamed ; Moaddeli, SaeedThe encyclopedia of Iranian architectural history was established with the goal of increasing the accessibility of the widespread resources and documents related to Iranian architectural history and to provide a better and more productive space for collaboration of researchers and scholars, enabling them to expand and improve this encyclopedia. The Infrastructure which is designed is a three level structure. We have a knowledge representation level on the top, an ontology of Iranian architectural history, a conceptual model designed for this specific area of study and The middle level is the mediator level which is responsible for establishing the relation between concepts and documents and enhancing search and semantic interoperability and The underlying level is a digital repository; a localized and customized version of Dspace institutional repository. The main changes that we made to Dspace was implementing the Persian calendar (a.k.a Jalali calendar) and fixing the correct representation of Persian numerals. We've also translated all the messages into Persian and changed the JSPUI for a correct view of page containing right-to-left text. A team of librarians in EIAH reviewed the work-flows and based on their feedback, some changes are made to the way the metadata appears for each item and the way work-flows progress. Using our EIAH Metadata standards we have our own Application Profile based on Dublin Core embedded in Dspace for describing the documents available in the history of Iranian architecture. Our Development plan for Dspace includes: A book viewer A customized search engine (lucene based) Federated search on multiple Dspace installations in national cultural heritage centers Establishing a connection between Semantic Mediawiki and Dspace through OAI-PMH Thumbnail generator for different text document formats Packaging Dspace for Redhat based systems Development of our Application profile based on Singapore framework for DCAP.

ItemIntroducing Vireo: an ETD Submittal and Management System for DSpace(Georgia Institute of Technology, 2009-05-20) Leggett, John ; McFarland, Mark ; Mikeal, Adam ; Phillips, ScottThe Texas Digital Library (TDL) is a consortium of public and private institutions from across the state of Texas; a major project in TDL is the development of a state-wide repository for managing the entire life-cycle of electronic theses and dissertations (ETDs). The Texas ETD Repository is a large effort that span multiple independent initiatives, all of which interact to support the overall task of managing ETDs in Texas. This presentation will describe Vireo, the customized submission and workflow management application that TDL developed for DSpace, and it's role within the Texas ETD Repository. We will describe its current implementation as a Manakin aspect and theme, and discuss the future plans for the application, including its release to the repository community under an open source license.

ItemDesigning and Implementing a Learning Object Repository: Issues of Complexity, Granularity, and User Sense-Making(Georgia Institute of Technology, 2009-05-20) Moen, William E.The Texas Center for Digital Knowledge at the University of North Texas is designing and implementing a DSpace/Manakin learning object repository (LOR) for the Texas Higher Education Coordinating Board to store and provide access to redesigned undergraduate courses being created through the Board's Texas Course Redesign Project (TCRP). The content for the THECB LOR differs in significant ways from content stored in other well-known and evolving LORs, since the content is in the form of complete or partial courses. While this content can be represented as a single learning object (i.e., a complete course as one learning object), the THECB LOR is making the complete courses available as learning objects and it is providing access to components of the courses' content as discrete learning objects for reuse and repurposing. A number of challenges and issues have emerged in the design, development, and implementation the LOR, and this paper focuses on three key aspects and the solutions we are pursuing: 1) complexity of the course content and granularity; 2) submission of complex objects and metadata; and 3) user interface design to assist users in making sense of this repository and its contents.

ItemConnecting with Students in their Digital World(Georgia Institute of Technology, 2008-03-20) Corson, Gerri ; Gettys, Rebecca ; Liss, KennethMore than three dozen academic libraries have used a new tool called LibGuides to create new kinds of research guides with a 2.0 look and feel. Librarians from the University of South Carolina will show how LibGuides has transformed their web presence by streamlining resources into a more dynamic and intuitive experience for their patrons. Boston College’s LibGuides project leader will show how LibGuides has changed not just the research guides but the librarians who created them, helping them shape and manage their online presence and interaction with students.
