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

Three Rs for Re-Use in Digital Preservation

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

A PDF Test-Set for Well-Formedness Validation in JHOVE - The Good, the Bad and the Ugly

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

Ingest and Storage of 3D Objects in a Digital Preservation System

The DURAARK project is developing methods and tools for the Long-Term Preservation (LTP) of architectural knowledge, including approaches to: enrich Building Information Models with “as built” information from scans, semantically enrich building models with additional data sets, preserve 3D models for future reuse. This deliverable defines the necessary steps for ingest and storage of 3D objects into anexisting OAIS compliant digital preservation system. It discusses how the gaps, which were previously identified and presented in deliverable D6.6.1, have been addressed in the DURAARK project so far. Developed methods and tools will be run against the DURAARK test set. Lastly, the existing drafts of the metadata schemas buildm for descriptive information and e57m and ifcm as technical metadata schemas for E57 and IFC respectively, will be extended significantly and presented in a digital preservation context

How Valid is your Validation? A Closer Look Behind the Curtain of JHOVE

Validation is a key task of any preservation workflow and often JHOVE is the first tool of choice for characterizing and validating common file formats. Due to the tool’s maturity and high adoption, decisions if a file is indeed fit for long-term availability are often made based on JHOVE output. But can we trust a tool simply based on its wide adoption and maturity by age? How does JHOVE determine the validity and well-formedness of a file? Does a module really support all versions of a file format family? How much of the file formats’ standards do we need to know and understand in order to interpret the output correctly? Are there options to verify JHOVE-based decisions within preservation workflows? While the software has been a long-standing favourite within the digital curation domain for many years, a recent look at JHOVE as a vital decision supporting tool is currently missing. This paper presents a practice report which aims to close this gap

“You say potato, I say potato” Mapping Digital Preservation and Research Data Management Concepts towards Collective Curation and Preservation Strategies

This paper explores models, concepts and terminology used in the Research Data Management and Digital Preservation communities. In doing so we identify several overlaps and mutual concerns where the advancements of one professional field can apply to and assist another. By focusing on what unites rather than divides us, and by adopting a more holistic approach we advance towards collective curation and preservation strategies. &nbsp

nestor endorsement of TRUST Principles

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-worthines

The ties that bind - On the impact of losing a consortium member in a cooperatively operated digital preservation system

Cooperatively operated digital preservation systems offer institutions of varying size the chance to actively participate in digital preservation. In current times of budget cuts they are also a valuable asset to larger memory institutions. While the benefits of cooperatively operated systems have been discussed before, the risks associated with a consortial solution have not been analyzed in detail. TIB hosts the Goportis Digital Archive which is used by two large national subject libraries as well as by TIB itself. As the host of this comparatively small preservation network, TIB has started to analyze the particular risk which losing a consortium member poses to the overall system operation. This paper presents the current status of this work-in-progress and highlights two areas: risk factors associated with cost and risk factors associated with the content. While the paper is strictly written from the viewpoint of the consortial leader/ host of this specific network, the underlying processes shall be beneficial to other cooperatively operated digital preservation systems
