The perfect companion for mastering the latest version of Fedora and RHELAs a free, open source Linux operating system sponsored by Red Hat, Fedora can either be a stepping stone to Enterprise or used as a viable operating system for those looking for frequent updates. Written by veteran authors of perennial bestsellers, this book serves as an ideal companion for Red Hat Enterprise Linux (RHEL) users and offers a thorough look at the basics of the new Fedora 12.Step-by-step instructions make the Linux installation simple while clear explanations walk you through best practices for taking advantage of the desktop interface. You'll learn how to use the Linux shell, file system, and text editor. Plus, the authors describe key system administration skills, such as setting up users, automating system tasks, backing up and restoring files, and understanding the latest security issues and threats.Walks you through new features of Fedora 12, the open source Linux operating system sponsored by Red HatCovers the latest networking, desktop, and server enhancements to Fedora 12Shares tips for taking advantage of the desktop interface; using and customizing the desktop menus, icons, window manager, and xterm; and automating system tasksDemonstrates how to backup and restore files and handle security threatsShows you how to create and publish formatted documents with Linux applicationsAccompanying DVD and CD-ROM include Fedora Linux 12 and an official Fedora 12 LiveCDWhether a new or power user of Fedora, you'll benefit from Fedora 12 and Red Hat Enterprise Linux Bible.

Indiana University was an early adopter of the Fedora repository, developing it as a home for heterogeneous digital library content from a variety of collections with unique content models. After joining the Hydra Project, now known as Samvera, in 2012, development progressed on a variety of applications that formed the foundation for digital library services using the Fedora 4 repository. These experiences have shaped migration planning to move from Fedora 3 to Fedora 4 for this large and inclusive set of digital content. Moving to Fedora 4 is not just a repository change; it is an ecosystem shift. End user interfaces for access, management systems for collection managers, and data structures are all impacted. This article shares what Indiana University has learned about migrating to Fedora 4 to help others work through their own migration considerations. This article is also meant to inspire the Fedora repository development community to offer ways to further ease migration work, sustaining Fedora users moving forward, and inviting new Fedora users to try the software and become involved in the community.

Memory institutions must be able to grow a fully-functional repository incrementally as collections grow, without expensive enterprise storage, massive data migrations, and the performance limits that stem from the vertical storage strategies. The Digital Repository at Scale that Invites Computation (DRAS-TIC) Fedora research project, funded by a two-year National Digital Platform grant from the Institute for Museum and Library Services (IMLS), is producing open-source software, tested cluster configurations, documentation, and best-practice guides that enable institutions to manage linked data repositories with petabyte-scale collections reliably. DRAS-TIC is a research initiative at the University of Maryland (UMD). The first DRAS-TIC repository system, named Indigo, was developed in 2015 and 2016 through a collaboration between U.K.-based storage company, Archive Analytics Ltd., and the UMD iSchool Digital Curation Innovation Center (DCIC), through funding from an NSF DIBBs (Data Infrastructure Building Blocks) grant (NCSA “Brown Dog”). DRAS-TIC Indigo leverages industry standard distributed database technology, in the form of Apache Cassandra, to provide open-ended scaling of repository storage without performance degradation. With the DRAS-TIC Fedora initiative, we make use of the Trellis Linked Data Platform (LDP), developed by Aaron Coburn at Amherst College, to add the LDP API over similar Apache Cassandra storage. This paper will explain our partner use cases, explore the system components, and showcase our performance-oriented approach, with the most emphasis given to performance measures available through the analytical dashboard on our testbed website.

Se presenta una revisión del estado de las aplicaciones informáticas para la gestión de repositorios digitales. Los gestores de repositorios disponen de distintas alternativas, al margen de las que han alcanzado una mayor popularidad en el área de los repositorios académicos, en particular DSpace o EPrints, que han evolucionado sustancialmente en sus últimas versiones. Esta evolución responde principalmente a la adopción de nuevos estándares diseñados en el contexto de la web semántica y los datos abiertos enlazados, y a la necesidad de incorporar a los productos funciones para la preservación digital. Se describe la evolución y las novedades incorporadas en las últimas versiones de los principales programas de código abierto u open source de gestión de repositorios atendiendo a los puntos anteriores. La selección se ha completado a partir de los datos disponibles en sitios de referencia como la Digital Preservation Coalition (DPC), Digital Curation Center (DCC), National Digital Stewardship Alliance (NDSA) y la Open Preservation Foundation. Las conclusiones señalan que una estrategia de archivo y preservación digital exige la utilización conjunta de distintos softwares, pues ninguno integra todos los componentes necesarios para implementar una estrategia de archivo digital y preservación efectiva.
