A Closer Look at Fedora's Ingest Performance

4th International Conference on Open RepositoriesThis presentation was part of the session : Fedora User Group PresentationsDate: 2009-05-21 10:30 AM – 12:00 PMIt is of paramount importance for large-scale applications that Fedora can handle huge amounts of data efficiently. While Fedora is generally known to be stable and reliable, there appears to be a lack of data and experience regarding large-scale installations and the performance implications thereof. FIZ Karlsruhe is currently working on several projects with large-scale Fedora repositories holding several million complex objects. We conducted extensive performance and scalability tests with the current Fedora software (mostly version 3.0), focusing on ingest operations. Our goal was to prove that Fedora actually scales well enough for our use cases. Our test runs provided us with data which helped us identifying limits and constraints, and devising some optimization recommendations

Creating and Sharing Fedora Installation Package for Ubuntu

4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PostersOpen repositories are enterprise information systems that face ongoing challenges of maintaining low operating costs, high efficiency, and high reliability. This poster proposal presents an open source strategy to help address some of these challenges. The NSF funded NSDL Materials Digital Library Pathway (MatDL) offers a Fedora-based open repository and is moving toward using the Ubuntu distribution of Linux on all of its servers to capitalize on the advantages of Ubuntu. However, currently there is no easy way to implement Ubuntu with Fedora-based repositories. This poster describes MatDL's efforts to co-develop and host a Fedora installation package for Ubuntu.The Materials Digital Library Pathway (DUE-0532831) is supported by the National Science Foundation

Enabling Inter-Repository Access Management between iRODS and Fedora

4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PresentationsDate: 2009-06-04 08:30 AM – 10:00 AMMany digital repositories have been built using different technologies such as Fedora and the integrated Rule-Oriented Data System (iRODS). This paper analyzes both the Fedora and iRODS technologies to understand how to integrate the two systems to enable cross-repository data sharing. The areas considered include the digital object model, services, management of distributed storage, external data resources, and policy enforcement.National Science Foundatio

Beyond the Tutorial: Complex Content Models in Fedora 3

4th International Conference on Open RepositoriesThis presentation was part of the session : Fedora User Group PresentationsDate: 2009-05-21 08:30 AM – 10:00 AMThe University of Wisconsin Digital Collections Center recently began a pilot project to create a digital collection of learning objects stored in a Fedora 3.1 repository. This pilot project is the proof-of-concept of many ideas and discussions, extending back for over five years, concerning the problem of storing, searching, and retrieving heterogeneous objects and object types, linked together in complex relations, in a way that is loosely coupled with front-end user display applications. During the course of this presentation, we will describe the issues we've confronted implementing increasingly rich digital collections over the past decade (including some real-life examples of complex digital objects), models we have developed with to resolve many of those issues, and how we have started implementing those models in Fedora 3.1, using the new Content Model functionality

Fedora and GSearch in a Research Project about Integrated Search

4th International Conference on Open RepositoriesThis presentation was part of the session : Fedora User Group PresentationsDate: 2009-05-21 10:30 AM – 12:00 PMThe Royal School of Library and Information Science in Denmark is performing a research project about integrated search. DTU Library provides assistance in the form of a Fedora and GSearch installation. The presentation will focus on the technical challenges involved in the setup and indexing of the various sources, facilitating the integrated search.DEFF, Denmark's Electronic Research Librar

Enhanced Content Models

With the release of Fedora Commons 3.0, the Content Model Architecture (CMA) was added to Fedora. It was not meant as an end-all solution, but rather as a starting point for building more advanced content models. The Fedora team expected the user community to figure out the best ways to use and amend this design. Now, the CMA have been around for a while, and certain improvements have, by agreement of the Fedora Committer Team, matured enough to be brought back into the core Fedora system, probably with the coming Fedora 3.4 release. This proposal aims to present these improvements to the Fedora community

The Fascinator - Desktop eResearch and Flexible Portals

4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PostersThe Fascinator is an Apache Solr front end to the Fedora commons repository. This project was originally funded by ARROW, as part of the mini project scheme. The Fascinator is written in Java. It drops into the Tomcat server that comes with Fedora. There are two ways this software can be used. It can be used as a server to deliver one or more portals with faceted searching and browsing or as an (experimental) desktop tool for managing eResearch assets and synchronising them with other repositories.ARROW project; Monash Universit

Islandora: a Drupal/Fedora Repository System

4th International Conference on Open RepositoriesThis presentation was part of the session : Fedora User Group PresentationsDate: 2009-05-20 03:30 PM – 05:00 PMIslandora is an open source Drupal 6/Fedora 3 module produced by the University of Prince Edward Island Library. Islandora provides a flexible collaboratve environment for the stewardship of digital resources. The Islandora 1.0 release includes content models and sample collections in all three major areas of the academic enterprise: administration, research, learning. The session will provide a detailed overview of the Islandora architecture, functionality, the growing community of collaborators as well as examples of production systems in all three major use areas

Project Hydra: Designing & Building a Reusable Framework for Multipurpose, Multifunction, Multi-institutional Repository-Powered Solutions

4th International Conference on Open RepositoriesThis presentation was part of the session : Fedora User Group PresentationsDate: 2009-05-20 03:30 PM – 05:00 PMThere is a clear business need in higher education for a flexible, reusable application framework that can support the rapid development of multiple systems tailored to distinct needs, but powered by a common underlying repository. Recognizing this common need, Stanford University, the University of Hull and the University of Virginia are collaborating on "Project Hydra", a three-year effort to create an application and middleware framework that, in combination with an underlying Fedora repository, will create a reusable environment for running multifunction, multipurpose repository-powered solutions. This paper details the collaborators' functional and technical design for such a framework, and will demonstrate the progress made to date on the initiative.JIS
