    A PDF Test-Set for Well-Formedness Validation in JHOVE - The Good, the Bad and the Ugly
    (Zenodo, 2017) Lindlar, Michelle; Tunnat, Yvonne; Wilson, Carl
    Digital preservation and active software stewardship are both cyclical processes. While digital preservation strategies have to be reevaluated regularly to ensure that they still meet technological and organizational requirements, software needs to be tested with every new release to ensure that it functions correctly. JHOVE is an open source format validation tool which plays a central role in many digital preservation workflows and the PDF module is one of its most important features. Unlike tools such as Adobe PreFlight or veraPDF which check against requirements at profile level, JHOVE’s PDF-module is the only tool that can validate the syntax and structure of PDF files. Despite JHOVE’s widespread and long-standing adoption, the underlying validation rules are not formally or thoroughly tested, leading to bugs going undetected for a long time. Furthermore, there is no ground-truth data set which can be used to understand and test PDF validation at the structural level. The authors present a corpus of light-weight files designed to test the validation criteria of JHOVE’s PDF module against “well-formedness”. We conclude by measuring the code coverage of the test corpus within JHOVE PDF validation and by feeding detected inconsistencies of the PDF-module back into the open source development process.

    nestor endorsement of TRUST Principles
    (Meyrin : CERN, 2020-09-25) Arnold, Denis; Lindlar, Michelle; Recker, Jonas; Schoger, Astrid; Schumann, Natascha
    Nestor - the German-speaking competence network for digital preservation - welcomes the TRUST principles as outlined in the white paper (https://doi.org/10.1038/s41597-020-0486-7) and joins the call for endorsement by the Research Data Alliance (https://www.rd-alliance.org/rda-community-effort-trust-principles-digital-repositories). nestor clearly sees the need for further development of the principles as they move into practise. As part of this, an ad-hoc WG TRUST discussed the principled and has released the statement "nestor endorsement of TRUST Principles". Benefits and recommendations at a glace • provides a common framework to facilitate discussion by all stakeholders • mnemonic helps to raise awareness • provides a low-threshold entry point • principles do not convey a sufficiently comprehensive picture of the requirements • preservation planning and suitable long-term preservation strategies are missing • TRUST Principles must be linked with established and accepted criteria suited to measuring trust-worthiness

    Three Rs for Re-Use in Digital Preservation
    (Meyrin : CERN, 2020-02-05) Lindlar, Michelle
    This presentation was given at the " Hergebruik / Re-use Seminar " held for and by Barbara Sierman at the KB Netherlands on February 5th, 2020. 4 speakers were given the topic "Re-Use", asking for their take on the subject. This presentations highlights how three attributes are closely connected / describe re-use: research-based, reproducible, responsible. It is shown how they connect to re-use and digital preservation and where the digital preservation community has room for improvement.

    D6.6.1 Current state of 3D object digital preservation and gap-analysis report ; DURAARK - Durable Architectural Knowledge ; FP7 - ICT - Digital Preservation
    (2014) Lindlar, Michelle; Saemann, Hedda; Ochmann, Sebastian; Gadiraju, Ujwal; Jonsson, Osten
    This deliverable identifies gaps in existing processes for the digital preservation of 3D objects. The gap analysis is approached through an in-depth analysis of two areas. One area is that of fundamental digital preservation tools and processes regardless of their content type. It describes processes and standards adapted by the global digital preservation community and implemented in archives of varying domains, e.g., archives dealing predominantly with e-publications as well as AV-archives. The second area is that of current existing processes for the digital preservation of 3D objects. It describes aspects and challenges which are uniquely tied to the long-term archiving process of this content-type and lists existing tools and standards. The gaps are identified through a comparison of the content type agnostic and the 3D-specific state of the art descriptions
