  1. An Analysis of Contemporary JPEG2000 Codecs for Image Format Migration: Paper - iPres 2013 - Lisbon

    Palmer, William; May, Peter; Cliff, Peter
    Despite the importance of web archives for the access to historical information published on the Internet, human interaction with web archives systems has not been thoroughly addressed. The web archive search user interface presented on this paper was derived from several rounds of development and usability testing over the Portuguese Web Archive search user interface (available at We present our findings gathered while adapting a typical web search user interface to the context of web archive search. We describe how we adapted a typical search user interface to address full-text and URL search over web-archived data, highlighting the unexpected...

  2. Database Preservation Evaluation Report - SIARD vs. CHRONOS: Paper - iPres 2013 - Lisbon

    Lindley, Andrew
    Preserving information systems is one of the greatest challenges in digital preservation. In this paper we outline the existing strengths and shortcomings of a record-centric driven preservation approach for relational databases by lining up a state-of-the art industry database archiving tool CHRONOS against SIARD one of the most popular products in the GLAM (galleries libraries archives museums) world. A functional comparison of both software products in the use cases of database retirement, continuous and partial archiving as well as application retirement is presented. The work focuses on a technical evaluation of the software products - organizational and process aspects of...

  3. Analysis of the variability in digitised images compared to the distortion introduced by compression: Paper - iPres 2013 - Lisbon

    Martin, Sean; Macleod, Malcom
    The paper evaluates the noise which is present in digitised images of very high quality and the noise/error which results when such images are compressed and then decompressed. The variations between pairs of captured images of identical material were compared and the two best pairs of images were identified. The variations between these pairs were then compared with the variations introduced by compression and decompression of those images. We found that even lossy compression can result in significantly lower variation than that between the best pairs of original images caused by imaging noise. We report the results of a qualitative...

  4. A Digital Archive of Monitoring Data: Paper - iPres 2013 - Lisbon

    Costa, Fábio; David, Gabriel; Cunha, Álvaro
    The change of status of data files from mere stepping stones to build other research products into publishable documents raises the question of how to organize data repositories appropriate for dissemination of such publications outside of the original research group. If the repository is to be used for the on-going research by the research group, it assumes the role of a digital archive. In this paper, a metadata model for the special case of projects relying on monitoring data is proposed and a prototype digital archive is described that has been built according to that model. This metadata is critical...

  5. A Framework for Automated Verification in Software Escrow: Paper - iPres 2013 - Lisbon

    Weigl, Elisabeth; Binder, Johannes; Strodl, Stephan; Kolany, Barbara; Draws, Daniel; Rauber, Andreas
    If a business is in need of customized software it often orders it from a third party developer. This can lead to a dependency on this developer regarding maintainability and development of the product. Software Escrow o_ers a mitigation to this as it includes a trustable escrow agent in the business relationship. The agent is responsible for depositing all material that is needed to develop the software, like source code, documentation, and licenses for software artifacts. If a prede_ned trigger event occurs, the agent is obliged to hand out the objects to the customer. Thus the material needs to be...

  6. A Collaboration to Clarify the Costs of Curation – The 4C Project: Poster - iPres 2013 - Lisbon

    Grindley, Neil
    This poster will describe actions being taken in the context of the 4C Project (a Collaboration to Clarify the Costs of Curation), an EC-funded two-year coordination action that aims to promote a better understanding of the potential for undertaking digital curation activity. The approach it is taking is to focus firstly on costs but then to link that concept to related ones such as benefits, value, risk and sustainability, therefore taking a holistic economic view of digital curation. This is important as it links up with various strands of previous work, both on costs and activity models; and on benefits,...

  7. Adapting search user interfaces to web archives: Paper - iPres 2013 - Lisbon

    Cruz, David; Gomes, Daniel
    We believe that our work can be applied to improve the quality of the services provided by other web archives.

  8. Acquiring and providing access to historical web collections: Paper - iPres 2013 - Lisbon

    Gomes, Daniel; Cruz, David; Miranda, João; Costa, Miguel; Fontes, Simão
    Every day, unique valuable information that describes our current days disappears from the web. National archives or libraries have been keeping cultural heritage for centuries by collecting and preserving past generation objects or printed media. Now, it is mandatory to preserve digital cultural heritage in the form of web content. The Portuguese Web Archive project began in 2008. Since then, it has periodically collected live-web content to be preserved but also acquired historical web collections from third-parties previously published. However, storing information before it vanishes from the web is not enough to make web archives useful to societies. Thus, the...

  9. An attempt at modeling differentiated storage for digitized collections: finding the balance between storage, costs and preservation of digitized publications: Paper - iPres 2013 - Lisbon

    Stoutjesdijk, Trudie
    The Koninklijke Bibliotheek (KB) digitizes the national collection of the Netherlands. Digitization leads to multiple versions of a publication: a digital access file, a digital master file, back-ups of the digital versions and the physical original publication. This in turn increases the need for storage capacity quickly. And raises questions like: Should all versions be stored? Do all the versions need to be preserved in order to ensure permanent access, and if so which ones should be preserved and how? Based on the collection care plan and the content strategy a differentiated storage policy is set up in order to...

  10. A new data model for digital preservation and digital archiving for the French Administration: VITAM model on NoSQL technologies: Paper - iPres 2013 - Lisbon

    Bregier, Frédéric; Deguilhen, Frédéric; Morin, Nathalie; Laperdrix, Marie; Fuentes-Hashimoto, Lourdes; Vasseur, Edouard; Van De Walle, Thomas
    The three ministries in charge of public digital archiving in France (Culture, Defence and Foreign Affairs) decided to build a specific system in order to preserve their digital information. The main challenge is the management of all the data and metadata produced by the French State which could be linked to Big data technologies. Since February 2013, these three ministries have done a large experiment (a proof of concept) based on NoSQL technologies, which ended in June 2013. In this paper, we describe our IT approach of this archivistic problem, our new data model and the results of this inter-ministerial...

  11. A Risk Analysis of File Formats for Preservation Planning: Paper - iPres 2013 - Lisbon

    Graf, Roman; Gordea, Sergiu
    This paper presents an approach for the automatic estimation of preservation risks for _le formats. The main contribution of this work is the definition of risk factors with associated severity levels and their automatic computation. Our goal is to make use of a solid knowledge base automatically aggregated from linked open data repositories as the basis for a risk analysis in the digital preservation domain. This method is meant to facilitate decision making with regard to preservation of digital content in libraries and archives. We have developed a tool for aggregating rich and trusted _le format descriptions. It exploits available...

  12. Archives New Zealand Migration from Fedora Commons to the Rosetta Digital Preservation System: Paper - iPres 2013 - Lisbon

    Hutar, Jan
    This paper discusses the New Zealand Government Digital Archive Programme (GDAP) and its requirement for Archives New Zealand to move to a fully functional digital preservation system. It looks at the migration of digital content from Fedora Commons to Ex Libris‟ Rosetta Digital Preservation System focusing on what needed to be migrated, preparation of the migration, how it was performed and what tools were needed to support the work. We look at the verification of this process and conclude with an audit of the results and a description of the lessons learned during this process.

The poster also describes Simon Fraser University’s plans to expand its digital preservation services using Archivematica, including integration of LOCKSS as a distributed storage network for content managed by Archivematica.

  14. Automatic Preservation Watch using Information Extraction on the Web: Paper - iPres 2013 - Lisbon

    Faria, Luís; Akbik, Alan; Sierman, Barbara; Ras, Marcel; Ferreira, Miguel; Carlos Ramalho, José
    The ability to recognize when digital content is becoming endangered is essential for maintaining the long-term, continuous and authentic access to digital assets. To achieve this ability, knowledge about aspects of the world that might hinder the preservation of content is needed. However, the processes of gathering, managing and reasoning on knowledge can become manually infeasible when the volume and heterogeneity of content increases, multiplying the aspects to monitor. Automation of these processes is possible [11, 21], but its usefulness is limited by the data it is able to gather. Up to now, automatic digital preservation processes have been restricted...

  15. Building Institutional Capacity in Digital Preservation: Paper - iPres 2013 - Lisbon

    Schultz, Matt; Phillips, Mark; Krabbenhoeft, Nick; Eisenhauer, Stephen
    The Chronicles in Preservation project, being led by the Educopia Institute, is undertaking research to evaluate the degree to which several of the current digital preservation standards in use today (e.g., OAIS, TRAC, PREMIS,METS, etc.) can be applied to the diverse and at-risk content genre of digital newspapers. Institutions need guidance on incremental, skilled approaches and lightweight tools and resources if they are going to begin caring for such content in achievable and yet sustainable ways. The Chronicles project has researched, experimented, and begun advocating for a variety of skills, tools, and other resources that both embrace the current standards...

  16. Benefits of geographical, organizational and collection factors in digital preservation cooperations: The experience of the Goportis consortium: Paper - iPres 2013 - Lisbon

    Lindlar, Michelle; Friese, Yvonne; Müller, Elisabeth; Bähr, Thomas; von Trosdorf, Anja
    Digital preservation is a resource intensive task, requiring specific systems, well-trained staff and an ongoing commitment to adopt new strategies and approaches as technology and/or user expectations change over the course of time. Cooperations to tackle this task are not a new idea - one of the first reports on digital preservation, commissioned by the Center for Preservation and Access (CPA) and the Research Library Group (RLG), recommended a "national system of digital archives” [12]. In the library context consortia date back to the 1970s, where they rose in the context of shared cataloguing efforts. Over the years experiences have...

  17. CLEAR: a credible method to evaluate website archivability: Paper - iPres 2013 - Lisbon

    Banos, Vangelis; Kim, Yunhyong; Ross, Seamus; Manolopoulos, Yannis
    Web archiving is crucial to ensure that cultural, scientific and social heritage on the web remains accessible and usable over time. A key aspect of the web archiving process is optimal data extraction from target websites. This procedure is difficult for such reasons as, website complexity, plethora of underlying technologies and ultimately the open-ended nature of the web. The purpose of this work is to establish the notion of Website Archivability (WA) and to introduce the Credible Live Evaluation of Archive Readiness (CLEAR) method to measureWA for any website. Website Archivability captures the core aspects of a website crucial in...

  18. Cloudy Emulation – Efficient and Scaleable Emulation-based Services: Paper - iPres 2013 - Lisbon

    Valizada, Isgandar; Rechert, Klaus; Meier, Konrad; Wehrle, Dennis; von Suchodoletz, Dirk; Sabel, Leander
    Emulation as a strategy for digital preservation is about to become an accepted technology for memory institutions as a method for coping a large variety of complex digital objects. Hence, the demand for ready-made and especially easy-to-use emulation services will grow. In order to provide user-friendly emulation services a scalable, distributed system model is required to be run on heterogeneous Grid or Cluster infrastructure. We propose an Emulation-as-a-Service architecture that simplifies access to preserved digital assets allowing end users to interact with the original environments running on different emulators. Ready-made emulation components provide a flexible web service API allowing for...

  19. Creating a Framework for Applying OAIS to Distributed Digital Preservation: Paper - iPres 2013 - Lisbon

    Zierau, Eld; Schultz, Matt
    This paper describes work being done towards a Framework for Applying the Reference Model for an Open Archival Information System (OAIS) to Distributed Digital Preservation (DDP). Such a Framework will be helpful for future analyses and/or audits of repositories that are performing digital preservation in highly distributed ways. A great deal of work has already been accomplished toward the Framework itself, including selective community reviews of a white paper, case study interviews with DDP practitioners, and an analysis of OAIS as it relates to DDP. The paper will provide background information on this set of work, describe the research carried...

  20. Digital preservation of epidemic resources: coupling metadata and ontologies: Paper - iPres 2013 - Lisbon

    D. Ferreira, João; Pesquita, Cátia; M. Couto, Francisco; J. Silva, Mário
    The preservation of epidemiological information is challenging in several aspects, since this is both a data-intensive and multidisciplinary subject, with large amounts of data spanning several domains of knowledge. We present, as a case study, the Epidemic Marketplace (EM), a platform dedicated to the preservation of epidemiological resources. To ensure integrity of the data, the EM uses a metadata model coupled with the Network of Epidemiology-Related Ontologies (NERO), a compilation of ontologies covering several domains of epidemiology. This enables users to quickly annotate their resources with concepts from those ontologies, increasing their visibility. Additionally, the ontologies of NERO offer support...
