Improving DSpace Backups, Restores, Migrations
Get PDFIn the past, backing up your DSpace contents has involved semi-synchronized backups of both your database and your files. Although this procedure generally works fine, it can prove problematic when you suddenly need to restore the contents of a single Community, Collection or Item (both metadata and files). There is also the problem of metadata and content files residing in separate backups - if either one of these backups becomes corrupted, it is nearly impossible to completely restore your DSpace contents. This talk will introduce a new DSpace feature being developed as part of the DuraCloud integration project. This new feature will allow you to export your entire DSpace Community / Collection hierarchy (including all Items, and their metadata and files) into a series of METS-based packages. These METS-based packages may be used to restore all of your DSpace contents (into another DSpace), or just the contents of a single Community, Collection or Item. These packages can also provide a more stable way to backup your DSpace contents, or an additional means of getting content in or out of DSpace. This work is based on a DSpace plugin built as part of the MIT PLEDGE project; however it has been updated to allow for a complete restore of your DSpace hierarchy
Terminology Services in a Digital Repository
Get PDFThe uses of controlled vocabularies in digital library applications can be expanded with ease when thesauri are made available using a standard service oriented architecture. Adopting this approach, the Indiana University Digital Library Program has been able to easily adapt existing tools to use controlled vocabularies and to better take advantage of a wide array of controlled vocabulary sources
Publikationsfonds der Universität Bielefeld
No full textAn der Universität Bielefeld wurde ein Publikationsfonds in einer Pilotphase eingerichtet, der helfen soll, dass eine Open Access Primärpublikation nicht durch anfallende Kosten verhindert wird. Wenn Wissenschaftlerinnen und Wissenschaftlern keine eigenen Mittel (Hausmittel, Drittmittel, DFG-Publikationspauschale etc.) zur Deckung von evtl. anfallenden Kosten zur Verfügung stehen, soll der Publikationsfonds einspringen. Dies ist insbesondere für Nachwuchswissenschaftler wichtig, die teilweise nicht über entsprechende eigene Mittel verfügen. Auch alternative Publikationsformen, etwa in den Geisteswissenschaften, sollen unterstützt werden
Grundlagen der Suchtechnologie
Get PDFNach einem kurzen historischen Abriss (vom ersten Register, über die ersten Idee einer Suchmaschine bis zu Google) wird die Vorgehensweise bei der automatischen Indexierung von Dokumenten vorgestellt. Wie gelangt ein Dokument in den Index und wie und welcher Reihenfolge (Ranking) wird es wieder ausgegeben. Anschließend werden die verschiedenen Suchtechnologie-Arten (Zeichenabgleichung, Reguläre Ausdrücke, Fuzzy-Suche, Phonetische Suche, Semantische Suche) und Ranking-Verfahren (Formale Sortierung, On-Page-Faktoren, On-Site-Faktoren, Link-Faktoren, Eigenschaften und Verhalten der Nutzer) vorgestellt. Zum Abschluss wird ein kurzer Ausblick auf Suchmaschinenoptimierung gegeben

Get PDFDSpace 1.6 usage statistics: What it can do for you?
Get PDFIntroduction
DSpace 1.6 has been extended with a new Apache Solr based statistics solution. This contribution to DSpace is the open-source version of @mire's commercial "Content and Usage Analysis" DSpace module. The DSpace 1.6 statistics offer storage of usage data including bitstream downloads, item display page visits, collection and community homepage visits, ...
DSpace Under the Hood: How DSpace works
Get PDFWhilst you don't need to be a mechanic to drive a car, it is helpful if you have a basic understanding of how a car works, what bits do different jobs, and how to top up your oil and pump up your tyres / tires. This presentation will give an overview of the DSpace architecture, and will give you enough knowledge to understand how DSpace works. By knowing this, you will also learn about ways DSpace could be used, and ways in which it can't be used
Preserving repository content: practical steps for repository managers
Get PDFFew people would disagree that preservation of repository content is important. Indeed, the stated aim of most repositories is to provide permanent open access to the material therein. Why, then, have so few repositories implemented practical action plans for long term preservation of their content? There could be several reasons. Although a number of preservation tools and services already exist, until now few have addressed the specific needs of repositories; in practical terms they have necessitated action that is additional rather than integral to repository workflow. Repository content is typically highly varied and complex, while descriptive metadata and file formats are used inconsistently and deposited by those without knowledge or expertise in managing digital assets. Busy repository managers with little, if any, experience in digital preservation have lacked time and confidence to tackle what is perceived as an important but complex and scary problem.
The JISC-funded KeepIt project is bringing together existing preservation tools and services with appropriate training and advice on preservation strategy, policy, costs, metadata, storage, format management and trust to enable the participating repository managers to formulate practical and achievable preservation plans. From the point of view of the repository manager, this presentation summarises the activities of the KeepIt project, describes the impact that the project has had on the participating repositories, and suggests steps that other repository managers might take to ensure preservation readiness
