Archiving of digital research data based on established standards and methods is an important part of the research data lifecycle. It guarantees the long-term transparency and reusability of research ...results. In the case of archaeological data, this is of particular importance for the preservation of unique and irreplaceable cultural heritage. To gain insight into the current state of affairs regarding long-term archiving in Germany, the SEADDA (Saving European Archaeology from the Digital Dark Age) COST Action (1) and the Commission on Archaeology and Information Systems in the Association of German State Archaeologists (2), with the support of the IANUS Research Data Center of the DAI (3), conducted a survey in spring/summer 2021. This article presents the results of the survey together with recommendations for further and supporting measures targeted at improving the long-term archiving of digital archaeological data in Germany.
Los cortos plazos de vigencia de las tecnologías de la información y de sus soportes digitales exigen su renovación frecuente para prevenir su obsolescencia o deterioro con la consiguiente pérdida de ...la información almacenada. El término Digital Dark Age anuncia un escenario de práctica imposibilidad de acceder a la información digital debido a la obsolescencia del soporte físico, de los formatos y, en general, de los entornos informáticos que la soportan. En el ámbito de la información geográfi- ca y cartográfica, parece un deber inexcusable preservar los datos que han servido de base para la toma de decisiones y conseguir que éstos puedan ser utilizados en los sistemas de información del futuro. El artículo presenta los principales concep- tos relacionados con la preservación de dicho tipo de información.
Los repositorios institucionales representan la denominada Vía Verde del movimiento Acceso Abierto, facilitando el acceso a la información y la gestión de la memoria científica de las universidades y ...centros de investigación. En ese sentido, no solo debe optimizarse su funcionamiento en términos de garantizar la organización y recuperación de los documentos sino también, los procesos de interoperabilidad y preservación digital. Es aquí donde el Open Archival Information System (OAIS) ha tomado lugar como el estándar que orienta y optimiza los procesos de cara a la preservación digital. A partir de lo anterior, este artículo da cuenta de los resultados de una investigación documental sobre el uso del modelo OAIS en repositorios institucionales, para ello se presenta la metodología de búsqueda desarrollada y el análisis de los factores a considerar en la gestión de los repositorios. Los resultados recopilan experiencias y categorías de implementación, principios básicos y esquemas de funcionamiento para atender condiciones de integralidad, interoperabilidad y facilidad en la recuperación y preservación de la memoria científica y académica de las instituciones. Principalmente se puede evidenciar una tendencia a modelos y arquitecturas distribuidas, mayor cantidad de experiencias en Europa y Estados Unidos y el uso de sistemas y software como DSpace, Lockss y Archivematica.
Este estudo analisa o modelo de informação do Open Archival Information System (OAIS), com ênfase nos conceitos básicos, e busca convergências com a arquivística. Para isto, perpassa questões como a ...gestão de documentos, a preservação em longo prazo e a linha de custódia ininterrupta, temas pertinentes para um sistema de arquivo confiável. Palavras-chave: OAIS; preservação digital; arquivística; repositório digital.
The National Archives of Modern Architecture（NAMA）digitizes its holdings for preservation and access. This report sets out the challenges such as data specifications and long term preservation that ...NAMA faces with. It also in troduces AtoM, a database system that NAMA is considering whether to adopt and Archivematica that enables digital preservation compliant with the OAIS Reference Model.

The paper explores the strategies and methods for preserving Linked Open Data (LOD). To this aim it first presents an overview of the main scientific initiatives that have dealt with this topic. Then ...it describes some digital technologies that may result useful for preserving LOD, providing some insights on their application to LOD. It also provides a concrete example of implementation of the Semantic Web technologies for preserving Linked Data. Finally, it suggests some specific themes and directions that should be further investigated in order to elaborate a comprehensive solution to this problem: the preservation of Linked Open Data cannot be demanded to a single tool or method, it is rather the result of technical, organizational and procedural choices that altogether make up a consistent framework for LOD preservation.
PurposeThis article explores the tension between the concept of a Designated Community (DC) as a foundational element in Trustworthy Digital Repository (TDR) certification and curators' uncertainty ...about how to interpret and apply this concept in practice.Design/methodology/approachThis research employs a qualitative research design involving in-depth semi-structured interviews with stakeholders in the Trustworthy Digital Repository Audit and Certification (TRAC) process.FindingsThe authors' findings indicate that stakeholders in the audit and certification process viewed their uncertainty about how to apply the concept of a DC in the context of an audit as a source of risk for digital repositories and the repositories' collections.Originality/valueThis article brings new insights to digital preservation by applying social theories of risk to trustworthy digital repository audit and certification processes, with an emphasis on the concept of DC.
The Open Archive Information System (OAIS) is a reference model for organizing people and resources in a system, and it is already adopted in care centers and medical systems to efficiently manage ...clinical data, medical personnel, and patients. Archival storage systems are typically implemented using traditional relational database systems, but the relation-oriented technology strongly limits the efficiency in the management of huge amount of patients' clinical data, especially in emerging cloud-based, that are distributed. In this paper, we present an OAIS healthcare architecture useful to manage a huge amount of HL7 clinical documents in a scalable way. Specifically, it is based on a NoSQL column-oriented Data Base Management System deployed in the cloud, thus to benefit from a big tables and wide rows available over a virtual distributed infrastructure. We developed a prototype of the proposed architecture at the IRCCS, and we evaluated its efficiency in a real case of study.
PurposeConventional approaches to digital preservation posit that archives should define a Designated Community, or future user group, for whom they preserve digital information. Archivists can then ...use their knowledge of these users as a reference to help them deliver digital information that is intelligible and usable. However, this approach is challenging for archives with mandates to serve wide and diverse audiences; these archives risk undermining their efforts by focusing on the interests of a narrow user group.Design/methodology/approachA unique approach to this challenge was developed in the context of a project to build a digital preservation program at the Ontario Jewish Archives (OJA). It draws from previous research on this topic and is based on a combination of practical and theoretical considerations.FindingsThe approach described here replaces the reference of a Designated Community with three core components: a re-articulation of the Open Archival Information System (OAIS) mandatory responsibilities; the identification of three distinct tiers of access for digital records; and the implementation of an access portal that allows digital records to be accessed and rendered online. Together with supplemental shifts in reference points, they provide an alternative to the concept of a Designated Community in the determination of preservation requirements, the identification of significant properties, the creation of Representation Information and in the evaluation of success.Originality/valueThis article contributes a novel approach to the ongoing conversation about the Designated Community in digital preservation, its application and its limitations in an archival context.
