4. January 1-8, 2005AICCSA Workshop 2005 ARC Arc, is one of the first federated searching services based on the OAI protocol. Arc harvests metadata from several OAI compliant archives, normalizes them, and stores them in a search service based on a relational database (MYSQL or Oracle). At present, we have over one million metadata records from over 80 data providers from various domains.Arc is now available for download at http://oaiarc.sourceforge.net/. It is released under the NCSA Open Source License. ARC Developers' Site Provided as a Public Service : ODU Digital Library Research Group

5. January 1-8, 2005AICCSA Workshop 2005 KEPLER In the Kepler project, we propose a framework that gives publication control to individual publishers, support speedy dissemination, and addresses interoperability. We extend the OAI framework to support what we call "personal data providers" or "archivelets". We have created a self- contained, self-installing software that allows the user to create and maintain a small, OAI-compliant archive - archivelet - easily.

6. January 1-8, 2005AICCSA Workshop 2005 NASA Raytheon The Raytheon Consolidated Information Technology Services (ConITS) contract has a requirement to create an integrated digital library environment that will support the automated harvesting of internal and external publicly available aerospace information. The digital library infrastructure shall be built using several modules that are interoperable with each other. The interoperability shall be achieved through the use of XML and the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH).

7. January 1-8, 2005AICCSA Workshop 2005 An OAI-Compliant Federated Physics Digital Library - ARCHON This project is building an Open Archives Initiative compliant federated digital library with an emphasis on physics for the National Science, Mathematics, Engineering, and Technology Education Digital Library (NSDL; http://www.nsdl.org/ ).

8. January 1-8, 2005AICCSA Workshop 2005 Secure Distributed Digital Libraries The object of this proposal is to deploy and evaluate the economic sustainability model for federated digital libraries like Archon using Shibboleth as the underlying access control management framework. A federated digital library such as Archon contains holdings from different contributors and supports higher level services such as discovery, cross referencing, and classification. Because of its varied contributors, Archon requires differential granularity of access both in terms of objects and the services.

9. January 1-8, 2005AICCSA Workshop 2005 An OAI based NCSTRL Jointly with Virginia Tech and the University of Virginia, we are re- implementing the Networked Computer Science Technical Reference Library (NCSTRL) to an OAI-based framework. This moves NCSTRL from its previous Dienst-based distributed searching paradigm to one of the metadata harvesting. Provided as a Public Service : ODU Digital Library Research Group

10. January 1-8, 2005AICCSA Workshop 2005 DP9 DP9 is an open source gateway service that allows general search engines, (e.g. Google, Inktomi) to index OAI-compliant archives. DP9 does this by providing consistent URLs for repository records, and converting them to OAI queries against the appropriate repository when the URL is requested. This allows search engines to index the "deep Web" contained within OAI compliant repositories. Provided as a Public Service : ODU Digital Library Research Group

11. January 1-8, 2005AICCSA Workshop 2005 INTEROP There are many approaches to achieve Digital Library (DL) interoperability. This project focuses on scaleable interoperation among non-cooperating digital libraries. In our paradigm, we define a Lightweight Federated Digital Library (LFDL) system, where a participating DL defines its external behavior through an XML specification and then registers itself with the LFDL. DL registration, removal, and modification are dynamic, and transparent to end-users. Provided as a Public Service : ODU Digital Library Research Grou

12. January 1-8, 2005AICCSA Workshop 2005 DEAN The Dean project develops methods to derive document networks from temporal patterns in the retrieval behavior of large groups of users. The generated networks can be applied to document linking and information recommendation service, as well as the scientometric study of document impact and document relations.

13. January 1-8, 2005AICCSA Workshop 2005 FreeLib - Peer To Peer Digital Library In the Peer-to-Peer Digital library project, we apply pure peer-to-peer techniques in the context of digital library to achieve self-sustainability, scalability, and to evolve communities of common interest. The evolution of communities is a key feature in the system and is based on analyzing the access patterns among nodes. The system has rich metadata-based search and publishing servic es. Every node in the system indexes a small collection, however, with the large scale of a peer-to-peer system, tremendous collection sizes are possible.

14. January 1-8, 2005AICCSA Workshop 2005 Extracting Metadata and Structure The long term vision of the Defense Technical Information Center (DTIC) is to fully automate the process of acquiring documents that have been published by other government agencies as PDF files and creating a fully searchable XML marked-up document. This project will build a system that can extract from a set of pdf files the basic structure of the documents and the textual metadata, and investigate the problems of extracting the the microstructure (such as figures, tables, references and equations )of the document.

15. January 1-8, 2005AICCSA Workshop 2005 Kepler Technical Report Library The Kepler Technical Report Library (KTRL) is a digital library (called a Kepler Group Server) of research papers published by CS ODU faculty members. These papers are published by CS faculty members by using the tool named Kepler archivelet. They are harvested by the KTRL that provides search and retrieval services.

16. January 1-8, 2005AICCSA Workshop 2005 Enhancing Infrastructure of OAI : Digital Library GRID / MOD_OAI In this work, we are enhancing the two key infrastructure components of the OAI framework by building: a Digital Library Grid to support a high performance OAI federated search service, and an Apache module, mod_oai, to enable OAI for the general Web community. mod_oai Funded by The Andrew W.

19. January 1-8, 2005AICCSA Workshop 2005 COMPLETED PhD WORK  Anan, Hesham, Digital Library Services for 3D Models. This dissertation focuses on incorporating 3D models into digital libraries. The objectives of this research is to develop a prototype of a digital library that provides develop a digital library storage and discovery services for 3D models. We introduce a novel compression technique that allows the progressive retrieval of 3D models. We use the compressed representation to develop a similarity measure used in the recognition and shape-based retrieval of the 3D measure for the recognition models. We provide browsing and navigation services based on these same similarity measures to enhance the response time when dealing with large collections.  Shi, Rong, Lightweight Federation of Interoperable Digital Libraries.
