EXECUTABLE ARCHIVES: Software integrity for data readability and validation of archived studies

© 2021 author(s). The text of this paper is published under a CC-BY license (https://creativecommons.org/licenses/by/4.0/)This paper presents practices and processes for managing software integrity to support data archiving for long term use in response to the regulatory requirements. Through a case study of a scientific software decommissioning, we revisit the issues of archived data readability. Established software lifecycle management processes are extended with archiving and data integrity requirements for retention of data and revalidation of data analyses. That includes the software transition from operational to archival use within the Executable Archive model that extends the traditional data archive with computing environments with software installations required to reproduce study results from the archived records. The content use requirements are an integral part of both data access and the software management considerations, assuring that data integrity is fully supported by the software integrityPeer reviewe

File formats for long-term preservation of electronic publications in the e-deposit system in the Czech Republic

This bachelor's thesis focuses on selection of archival formats for the purposes of long term preservation of electronic pulications within the Czech e-deposit system. It analyzes the current situation in the Czech Republic and, on the basis of a sample of seven foreign institutions, compares it with foreign approaches and experiences. The first part of the thesis deals with the electronic formats of electronic books on the theoretical side. Based on the market analysis, the formats relevant to the Czech market for electronic publications are identified and the risks of the individual formats are described with regard to the possibilities of their long-term preservation. The second part is devoted to case studies in which the format policies of foreign libraries dealing with long-term archiving of electronic publications are documented. An analysis of electronic publications, voluntarily deposited by the publisher to the NL CR during the pilot operation of the e-deposit system, is also performed. The conclusion of the thesis summarizes the findings in the form of recommendations for archival formats for the further development of the Czech e-deposit system.Bakalářská práce se zabývá výběrem archivačních formátů pro potřeby dlouhodobého uchovávání elektronických publikací v rámci českého systému pro e-deposit. Analyzuje současný stav v ČR a na základě vzorku sedmi zahraničních institucí jej porovnává se zahraničními přístupy a zkušenostmi. První část práce se zabývá elektronickými formáty elektronických knih po teoretické stránce. Na základě analýzy trhu jsou určeny formáty relevantní pro český trh s elektronickými publikacemi a jsou popsána rizika jednotlivých formátů s ohledem na možnosti jejich dlouhodobého uchování. Druhá část práce je věnována případovým studiím, ve kterých jsou zdokumentovány formátové politiky zahraničních knihoven, zabývajících se dlouhodobou archivací elektronických publikací. Je také provedena analýza dat elektronických publikací, dobrovolně odevzdaných vydavateli do NK ČR v rámci pilotního provozu systému pro e-deposit. Závěr práce shrnuje zjištěné poznatky formou doporučení archivačních formátů pro další rozvoj českého systému pro e-deposit.Institute of Information Studies and LibrarianshipÚstav informačních studií a knihovnictvíFilozofická fakultaFaculty of Art

Digital Preservation Should Be More Holistic: A Digital Stewardship Approach

A considerable amount of creative, cultural, and research output is expressed in digital form. It is imperative that the memory sector rapidly improve its capability and capacity for handling digital content in all forms, including complex data. It took gallery, library, archive, and museum (GLAM) sector institutions somewhere between decades and centuries to implement systems for managing physical collections. Those who work with digital content are acutely aware that the same time frames are not afforded when it comes to saving our digital cultural heritage. The “fragility” of content produced from computing environments — thanks to the rapid churn of technological innovation and obsolescence — means that even acquiring, preserving, and providing sustained access to a seemingly “simple” stand-alone file can take considerable effort. The interdependencies and limitations of the computing platforms, software, hardware, and other peripherals (whether mass-manufactured or custom-developed) bring a level of complexity that is typically not experienced with physical collections

Building information modeling – A game changer for interoperability and a chance for digital preservation of architectural data?

Digital data associated with the architectural design-andconstruction process is an essential resource alongside -and even past- the lifecycle of the construction object it describes. Despite this, digital architectural data remains to be largely neglected in digital preservation research – and vice versa, digital preservation is so far neglected in the design-and-construction process. In the last 5 years, Building Information Modeling (BIM) has seen a growing adoption in the architecture and construction domains, marking a large step towards much needed interoperability. The open standard IFC (Industry Foundation Classes) is one way in which data is exchanged in BIM processes. This paper presents a first digital preservation based look at BIM processes, highlighting the history and adoption of the methods as well as the open file format standard IFC (Industry Foundation Classes) as one way to store and preserve BIM data

Una panoramica delle strategie di conservazione di opere d’arte digitale

This text presents a guide to long-term conservation strategies for digital artwork. In addition to a brief presentation of each strategy mentioned in the literature on the subject, the reader will find a first approach to the main problems and bibliographical references to technical discussions. The consulted studies speak of a series of strategies among which museum employees and conservation professionals must choose on a case-by-case basis depending on the nature of the work. In fact, digital art works have characteristics (the physical components, the architecture of computer programs and the communicative and interactive aspects) that are extremely multiform and variable during their life cycle. The examples of works collected from the bibliography represent this fluid scenario. The computer allows the creation of new artistic languages, new forms and new aesthetics (such as virtual or augmented reality) which undermine conservative practices and principles linked to the preservation of material objects. Digital art is a type of conceptual, ephemeral and procedural art and it presents similarities with the conservative issues of contemporary art. Added to this are problems related to the use of computer networks, the miniaturization of physical components (hardware) and the extreme volatility of instructions (software) in computer language. The latter are given by the programmer/artist who often leaves his "mark" within them. Because operating system, computers and storage media have a short life cycle and are rapidly replaced by research and market innovations, digital works remain behind and, without any conservation measure, are condemned to illegibility in a few years. The literature on the subject privileges the conservation of the intangible and conceptual components of the artistic product compared to the physical and technological ones. The latter quickly become obsolete and may (must) be replaced or adapted to the context over the long term

Preservation Planning for Digital Audio-Visual Material at the German National Library of Science and Technology (TIB) – Developing a Catalogue of Criteria and a Migration Plugin

The German Nation Library of Science and Technology (TIB) runs a digital archive in order to preserve its digital holdings which consists amongst others of audio-visual material. In order to identify obsolete audio-visual file formats a catalogue of criteria is developed and file formats which represent the majority of TIB’s audio-visual holdings are examined. The assessment reveals that the examined file formats are not a preferred file format for digital preservation, but on the other hand they are not at risk to become obsolete to TIB’s designated community. Furthermore, a migration plugin for the digital archive’s software environment is developed and successfully deployed. The migration plugin can be used during preservation planning in order to migrate the examined formats into TIB’s chosen archival file format if a migration becomes necessary
