    Islandora as an access system for iRODS managed information packages (2015)
    Details
    Publication Date: 2020-12-11
    Description: Accessing information packages with Islandora is straight forward, albeit not so much when they reside within a federated data management environment. In our case, dissemination information packages live in the Fedora object store for immediate access. The archival information packages are stored safely in a hierarchical storage infrastructure managed by iRODS and are only accessible for administrative and preservation action purposes. We present a data model that supports both use cases utilizing just a single Islandora instance. To integrate with iRODS, we developed an Islandora module to display and deliver data and metadata from the storage location. This solution also allows us to extend the system with further preservation workflow actions that will be required in the future.

    One Core Preservation System for All your Data. No Exceptions! (2015)
    Details
    Publication Date: 2020-12-11
    Description: In this paper, we describe an OAIS aligned data model and architectural design that enables us to archive digital infor- mation with a single core preservation workflow. The data model allows for normalization of metadata from widely var- ied domains to ingest and manage the submitted information utilizing only one generalized toolchain and be able to create access platforms that are tailored to designated data con- sumer communities. The design of the preservation system is not dependent on its components to continue to exist over its lifetime, as we anticipate changes both of technology and environment. The initial implementation depends mainly on the open-source tools Archivematica, Fedora/Islandora, and iRODS.

    PDF/A considered harmful for digital preservation (2017)
    Details
    Publication Date: 2020-12-11
    Description: Today, the Portable Document Format (PDF) is the prevalent le format for the exchange of xed content electronic documents for publication, research, and dissemination work in the academic and cultural heritage domains. erefore it is not surprising that PDF/A is perceived to be an archival format suitable for digital archiving work ows. is paper gives a rather short overview about the history and technical complexity of the format, its bene ts, shortcomings and potential pitfalls in the area of digital preservation with respect to aspects of accessibility and reusability of the information content of PDF/A. Several potential problems within the creation, preservation, and dissemination contexts are identi ed that may create problems for present and future content users. It also discusses some of the risks inherent to PDF/A for parts of the preservation community and suggests possible strategies to mitigate problems that might prevent future human or machine-based usability of the data and information stored within digital archives.

    Implications of perceived preservation levels (2018)
    Details
    Publication Date: 2020-12-11
    Description: This paper describes and explores the concept of perceived preservation levels and their implications. Perceived preservation levels are a way to communicate preservation policies, options and actions to the various stakeholders in digital preservation a digital preservation system is capable and able of. While explicitly assigned or stated preservation levels are promises to adhere to a certain set of policies and decisions, it may be hard to impossible for a best effort preservation service to fulfill these expectations. Perceived preservation levels combine different outcomes from preservation actions with preservation options and available resources to convey a holistic view of the archive’s worflow and decision states. A preservation system providing information about current states of digital objects puts the data producers in a position to reassure themselves of the trustworthiness of the archive without the need of formal certification. This openness has implications not only for the trust relationship between producer and archive but provides the opportunity to constantly reassess the archive’s decisions and priorities from the outside.
