NISO Two-Part Webinar: Sustainable Information
Part 2: Digital Preservation of Audio-Visual Content
About the Webinar
Audio-visual resources in digital formats present even more challenges to preservation than do digital text resources. Reformatting information to a common file format can be difficult and may require specialists to ensure it is done with no loss in integrity. While digital text may still be usable if done imperfectly (e.g. skewed but still readable pages), even small errors in digital A/V files could render the material unusable.
This webinar will share the experiences of several projects that are working to ensure that A/V files can be preserved with their full integrity ensured.

The document discusses strategies for digitally preserving content with limited resources. It recommends using standard file formats like TIFF and WAV to mitigate obsolescence. Consistent workflows, file naming, and metadata practices are also advised. For storage, it suggests starting with CD-Rs or DVDs and upgrading to hard drives and tapes when possible. Regular verification of transferred files and creation of checksums are important preservation steps. The UW Digital Collections Center piloted digital preservation practices by establishing scanner performance baselines and custom workflows for preservation-level digitization.

e-Services to Keep Your Digital Files Currentpbajcsy
This document summarizes technologies to support file format conversions for digital preservation. It presents three services: (1) a Conversion Software Registry to find conversion software between formats, (2) a File Conversion Engine to automatically execute conversions via third-party software, and (3) File Comparison Engines to evaluate information loss from conversions. These services aim to help archivists select preservation formats and evaluate conversion quality at scale. The document outlines related challenges and how the services address issues like software extensibility and computational requirements for large-scale conversions and comparisons.
The document discusses digital preservation and file format selection for long-term preservation of digital assets. It notes that file formats can become obsolete over time and presents five criteria for selecting preservation-suitable formats: 1) widespread adoption, 2) lack of technological dependencies, 3) disclosure of specifications, 4) transparency/identifiability, and 5) ability to embed metadata. It also discusses using a "performance model" where the significant properties and essence of a digital object are maintained regardless of file format changes over time. The key recommendation is to select file formats that align with a preservation strategy articulating the repository's purpose and community needs.
Slides accompanying a presentation given by Dan Gillean of Artefactual Systems at the PERICLES/DPC joint conference and meeting, "Acting on Change: New Approaches and Future Practices in LTDP," held in London at the Wellcome Collection Conference Center, Nov 30 - Dec 2, 2016.
The talk examines the question of the Capacity Gap - why is it that we have so many tools, services, standards, models, and metrics to support digital preservation, but so many organizations feel they do not have the capacity or capability to begin tackling digital preservation within their institution?
The presentation offers a different take based on Dan's experience working as an analyst and consultant for a software development company engaging with many different types of organizations and individuals in the cultural heritage sector. While acknowledging that the under-resourced nature of cultural heritage work plays a key role, this presentation examines some oft-encountered perceptual or cognitive barriers to getting started with digital preservation. It then provides some suggestions on how to overcome these barriers, acknowledging that anything is better than nothing when it comes to DP, and that sometimes perfect can be the enemy of good.

A presentation on Digital Library Software by Rupesh Kumar A, Assistant Professor, Department of Studies and Research in Library and Information Science, Tumkur University, Tumakuru, Karnataka, India.
This presentation introduces preservation workflow, a process to manage the risk associated with file formats of different digital objects. It was given as part of module 3 of a 5-module course on digital preservation tools for repository managers, presented by the JISC KeepIt project. For more on this and other presentations in this course look for the tag 'KeepIt course' in the project blog http://blogs.ecs.soton.ac.uk/keepit/
The purpose of digital preservation is to ensure continued access to digital objects over time as technologies change. This requires both passive preservation through secure storage and active preservation such as migration to new file formats or emulation. Characterization, planning, and action are important steps in the preservation process. Tools like PRONOM, LOCKSS, EPrints, and DSpace can help with various aspects of passive and active preservation. The National Library of Korea's OASIS system collects and preserves Korean digital resources through workflows that involve selective collection, processing, metadata, and long-term preservation.
This document provides an overview of building an institutional repository, including:
- Repository structure with communities, collections, and items
- Metadata standards like Dublin Core
- User roles and permissions
- Item submissions and workflows
- Copyright issues and embargoes
- Gathering usage statistics and registering the repository
- Ensuring quality control of metadata and submissions
Slides for a presentation made at the Archives Association of British Columbia's 2016 Annual Conference, April 15, 2016, held in Vancouver, BC, Canada.
The slides aim to provide users with a basic introduction to some of the key considerations when implementing a digital preservation plan, describing the workflow with a series of cooking-related references.
This document provides an overview of Archivematica and Access to Memory (AtoM) and how they can be used together for digital preservation and access. Archivematica is an open source digital preservation system that uses standards to create preservation packages (Archival Information Packages or AIPs) while AtoM is a content management system that can be used to describe and provide access to content. The document discusses how content could be described and managed in AtoM, preserved using Archivematica, and then have access copies and metadata handed back to AtoM for access. Integration with other systems like DSpace is also mentioned. Key features of Archivematica like standards compliance, flexibility and handling different types of digital content are
This document discusses end-to-end digital preservation for diverse collections using open source tools Archivematica and Access to Memory (AtoM). It provides overviews of Archivematica, which creates standards-based Archival Information Packages (AIPs) for long-term preservation, and AtoM, which allows for standards-based description and access in a multilingual, multi-repository environment. Integration between the two is described to provide a workflow where content is preserved using Archivematica and metadata and access copies are managed and provided in AtoM.
Software's now-a-days became the life line of modern day organizations. Libraries also need software if they want to create a parallel digital library with features which we may not find in a traditional library.
This presentation discusses the development of Archival Information Packages (AIPs) for NASA HDF-EOS data. It outlines the components of an AIP according to the OAIS reference model. It then describes efforts to implement AIPs using standards like METS, PREMIS, ISO 19115 and HDF-5 to package HDF data files with associated metadata. The goals were to prototype AIPs at the data set and granule level and test the usability of digital library standards for geospatial data. Next steps involve further work applying these standards to create preservation-ready packages of NASA's HDF data holdings.
Introduction to Digital Humanities: Metadata standards and ontologies LIBIS
Metadata standards and ontologies are important for digital humanities research. Key points from the document include:
- Standards help ensure consistency, reliability, and interoperability. They are developed through an open process involving interested parties.
- The standards landscape includes formats, technical protocols, descriptive standards for libraries, archives, and museums. Dublin Core is commonly used for discovery.
- Ontologies provide rules for describing context and relationships through semantic web technologies like RDF. They help link and integrate data.
- Standards and ontologies in digital cultural heritage include BIBFRAME, CIDOC-CRM, SKOS, and others to represent information for discovery, interpretation, and reuse.
Navigating the Analog Waves: Digitizing Audio Cassettes for Your CollectionKay Gregg
The document outlines the goals and process of a project to digitize and provide online access to audio recordings from the archives of the Quest Club of Fort Wayne, a local lecture society. The project involved setting up a digitization station, creating metadata standards, digitizing the cassette tapes to an archival format, and making the collection available online through a content management system. Key lessons learned included the importance of project management and planning for sustainability beyond the initial project.
Using Fedora Commons To Create A Persistent ArchivePhil Cryer
With the increasing amount of digital data and demand for open access to view and reuse such data continually increasing, the adoption of open source digital repository software is critical for long term storage and management of digital objects. By utilizing the open source Fedora Commons software, the Missouri Botanical Garden has created a stable, persistent archive for Tropicos digital objects, including specimen images, plant photos, and other digital media. Metadata, organized in standard Dublin Core extracted from Tropicos, are stored alongside the digital objects providing search and sharing of data via open standards such as REST and OAI, opening the door for mash-ups and alternative uses. The presentation will cover initial discovery, required hardware and software, and an overview of our experience implementing Fedora Commons. Lessons learned, pros and cons, and other options will also be covered.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

31. Hydra-Blacklight: An Open
Source Stack for AV
Preservation (and More)
December 2014
Tom Cramer
Chief Technology Strategist
Stanford University Libraries
@tcramer
32. What Is Hydra?
• A robust repository fronted by feature-rich,
tailored applications and workflows (“heads”)
➭ One body, many heads
• Collaboratively built “solution bundles” that
can be adapted and modified to suit local
needs.
• A community of developers and adopters
extending and enhancing the core
➭ If you want to go fast, go alone. If you
want to go far, go together.
33. Fundamental Assumption #1
No single system can provide the full range
of repository-based solutions for a given
institution’s needs,
…yet sustainable solutions require a
common repository infrastructure.
42. A Note on Ruby on Rails
• Rapid application development for web
applications: “Convention over configuration”
– 10x productivity
• Supportable: MVC (Model-View-Controller) and
Rails framework make code well-structured,
predictable
• Testable: Rspec and Cucumber give powerful,
automatable, testing tools
• Learnable: Stanford went from 1 to 8 Ruby savvy
developers in one year (no new hires)
– 1 week learning curve to basic proficiency
43. A Note on Fedora
• Flexible, Extensible, Durable Object
Repository Architecture
– Flexible: model and store any content types
– Extensible: easy to augment with apps and services
– Durable: foundation of preservation repository
• Proven, sustained and successful digital
repository
– 100’s of adopters; 13 years of development, 4 releases
– Vibrant community & funding under DuraSpace
• Fedora 4.0 released this month;
co-evolving with Hydra
44. Fedora 4 Preservation-Friendly Feature Set
• Auditing, versioning & fixity services
• Clustering & scalability
• Event-driven architecture
• Advanced storage capabilities
– Including support for very large files
• “Projection” over remote file stores
• Native RDF support
45. A Note on Blacklight
• Repository-agnostic, feature-rich, content-
aware, turnkey access interface
• Vibrant, multi-institutional, open source
community on its own
• Can be used independently, or as the first
component of, Hydra
• 100s of adopters worldwide; ~450 members of
the blacklight-development list
46. Rock & Roll Hall of Fame: Blacklight for Catalog, EAD and Media
51. Fundamental Assumption #2
No single institution can resource the
development of a full range of solutions on
its own,
…yet each needs the flexibility to tailor
solutions to local demands and workflows.
52. Hydra Philosophy -- Community
• An open architecture, with many
contributors to a common core
• Collaboratively built “solution bundles” that
can be adapted and modified to suit local
needs
• A community of developers and adopters
extending and enhancing the core
• “If you want to go fast, go alone. If you
want to go far, go together.”
One body, many heads
53. Community
• Conceived & executed as a distributed, collaborative,
open source effort from the start
• Initially a joint development project between Stanford,
Univ of Virginia, and Univ of Hull
• Hydra Partners are the backbone of the project
• Coalition of the willing
• No fees or dues
• Apache-style consensus and governance
• Steering Group provides administration, continuity, and
serves as backstop when needed
• But no central planning, no Project Director, no “one” architect
54. Hydra Partners…
…are individuals, institutions, corporations or
other groups that have committed to contributing
to the Hydra community; they not only use the
Hydra technical framework, but also add to it in
at least one of many ways: code, analysis,
design, support, funding, or other resources.
Hydra Partners collectively advance the project
and the community for the benefit of all
participants.
https://wiki.duraspace.org/display/hydra/Hydra+Community+Framework
55.
56. Code Licensing
• All Hydra code is available under Apache
License, Version 2.0
• All code commitments are being managed
through Contributor License Agreements
• Individual – so each developer is clear about
what they are contributing
• Corporate – so each institution is clear about
what it is contributing
• Code contributors maintain ownership of
their IP
• …and grant a non-exclusive license to the project
and its users
67. HydraDAM2
• NEH just funded Indiana & WGBH for 2nd
round of HydraDAM development
• Exercise HydraDAM on Fedora 4
• RDF-based data models
• Flexible storage
• Integrate HydraDAM (back-end) with Avalon and
OpenVault (front-ends)
• Integrate with mass digitization workflows
• 2 year effort
