Questionnaire for the self-assessment of digital preservation activities in institutional research repositories
<p>This dataset includes a questionnaire designed to enable institutional repository managers to conduct a self-assessment of their digital preservation strategies and activities. It consists of 46 evaluation criteria extracted and modified from the NDSA Levels of Digital Preservation and ISO 16363:2017 standards. The questionnaire is provided in queXML format, facilitating its import into various survey applications</p> <p> </p>
Preserving and sharing born-digital and hybrid objects from and across the National Collection (Decision-Making Model)
<p>When considering the complex challenges faced by cultural heritage organisations in collecting, preserving and sharing born digital and hybrid objects, it becomes clear that the process of defining solutions as a community of practice is in its early probing phase: characterised as tentative, exploratory, questioning, experimental. The workshops within this Preserving and sharing born-digital and hybrid objects from and across the National Collection project, which examined the case studies from multiple angles, yielded a richly discursive examination of the main considerations.</p> <p>This Decision Model represents an attempt to create a structured representation of those main considerations and the discourse from the workshops, to codify the main decision-making processes that an organisation may go through when assessing an acquisition of such an object, categorised into high level areas. It attempts to create a traversable system that could be used by collections professionals in their work - policy makers, managers, collections management or digital preservation practitioners, conservators.</p>
Preserving and sharing born-digital and hybrid objects from and across the National Collection (January 2022)
<p>This report is one of a set of outputs from the Arts and Humanities Research Council funded project ‘Preserving and sharing born-digital and hybrid objects from and across the National Collection’. It has been designed to provide an extensive account of the project research activities and findings, to be useful to museum, heritage, and preservation professionals, as well as to scholars interested in born-digital materials.</p>

FIGURE 5 in A novel application of the white light/fringe projection duo: recovering high precision three-dimensional images from fossils for the digital preservation of morphology
FIGURE 5. Processed views of a fossil sample acquired by the optical FPP system OTY. Each view is re-oriented 60º degrees with respect to the prior. Where: "a" indicates a zone that has no information at 60º in this stage of the process and will be corrected with the information of the next view, as is shown in "b".
FIGURE 3 in A novel application of the white light/fringe projection duo: recovering high precision three-dimensional images from fossils for the digital preservation of morphology
FIGURE 3. Magnitude maps of the sample obtained every 60º for 8 and 128 pixels/period. The images show the resolution and detail levels given the number of fringes projected over the sample. The measurements' accuracy of surface and depth depends on the number of projected fringes, which include as many as the system can display (8 pixels/period for each fringe in this case). When the acquisition of details is difficult, a wider fringe is required (based on our sample size, we used 128 pixels).

"The sound comes from a meadow in the Sierra Nevada Mountains in California. The meadow is at an elevation of 2400 meters near a mountain named Olancha Peak, which is 3700 meters in altitude. Ihave a group of friends with which Ibackpack (trek) into the mountains. Our goal was to spend some time in the mountains and hike to the top of Olancha Peak (…) By the time we reached the meadow, we were in a forest and there was still snow on the ground in some places. We took the trip in June of 2006. The Sierra Nevada Mountains are a large mountain range. Much of the range is protected by national parks or preserved areas we call 'wilderness areas' (…) Ihave been backpacking for nearly 40 years and Iwill hopefully continue with this challenging activity for 40 years more! Many of my friends are much younger than Iam and it gives me much satisfaction to be able to have as much or more stamina for this activity than they have! When we are on these trips, we hike up peaks, catch fish, drink some whiskey around campfires and enjoy our time in the beautiful solitude. My memories of this trip were of the steep, hot hike from the desert to the cool meadow; the overall beauty of the nature, the absolute solitude of our campsite near the meadow; the strenuous hike to the top of Olancha Peak; the camaraderie of my friends; and, of course the sound of the frogs in the meadow. The frog sounds were astounding to me and Iwould listen in awe of the creature's instinctual desire to reproduce and continue the existence of their kind. Surely there were different species in the meadow for some of the frog sounds were different than others. The sounds only occurred after the Sun went down for the evening. Istood next to the creek in the meadow and recorded the sounds using my digital camera." [Peter/plentz1960]16 in Collecting Sounds. Online Sharing of Field Recordings as Cultural Practice

<p><strong>The HTML publication is available at <a href="https://nfdi4culture.de/go/E5342" target="_blank" rel="noopener">https://nfdi4culture.de/go/E5342</a>.</strong></p> <p>The guideline conveys the basics of digital preservation, introduces digital archives in NFDI4Culture, explains the path of research data into the digital archive, explains the OAIS model and introduces preservation strategies. The focus is on cultural assets.</p>
The Outer OAIS - Inner OAIS (OO-IO) Model and use in Distributed Digital Preservation (DDP)
<p>This recording provides an overview (38 minutes) of the Outer OAIS-Inner OAIS (OO-IO) Model by Eld Zierau. The OO-IO model uses the Open Archival Information System (OAIS) Reference Model to provide a more detailed explanation of distributed digital preservation. Eld ZIerau, a digital preservation specialist at the Royal Danish Library, envisioned and specified the OO-IO model. Nancy McGovern, Director of Digital Preservation at MIT Libraries, collaborated on and contributed to the OO-IO model.</p> <p>This upload is identical to the version on Vimeo: https://vimeo.com/233024801</p>
Digital Preservation for the Masses: Creating Workflows for Institutions & Under-Resourced Organisations
<p>Digital preservation for the masses: Creating and publishing workflows and guidelines for institutions and smaller organisations interested in digital preservation, data management, and archiving</p> <p>Presentation given by Julia Colleen Miller at the Language Documentation and Archiving conference</p> <p>Creating public documentation is a crucial step in providing transparency of archiving processes, helping maintain consistent institutional knowledge, and making available resources for those wanting to know about digital preservation, archiving or data management. To this end, PARADISEC's pre-existing archiving workflows have been reworked and new technical workflows and archiving help-guides [1] have been developed and made available on GitHub.</p> <p>These resources can provide guidance for other archives, but perhaps more importantly, to empower smaller communities with fewer available resources wishing to preserve their own cultural materials. The archiving guides discuss topics such as data management and metadata. Technical workflows include digitising audio tapes, creating high-resolution photographs of manuscripts and notebooks, and processing born-digital audio and video files, closely following specifications [2] set out by the International Association for Sound and Audiovisual Archives and refined with input from holding institutions such as The National Library of Australia, The National Film and Sound Archive and The Language Archive based at the Max Planck Institute for Psycholinguistics.</p> <p>Cultural institutions including the Australian Institute of Aboriginal and Torres Strait Islander Studies and the National Film and Sound Archive have discussed their concerns to get their magnetic tape holdings digitised by 2025- a deadline beyond which access to functioning digitising equipment will become increasingly difficult and costly [3], [4]. Collaboration and capacity building will bring us closer to preserving at-risk cultural material before it is too late.</p> <p>References: [1] Miller, JC (2021) PARADISEC archiving workflows. https://paradisec-archive.github.io/PARADISEC_workflows/.
