Relational database management systems are one of the essential building blocks of information technology. Ubiquitous but often obscured behind layers of scripting, processing, forms and queries, they are arguably the most important invention of the Twentieth Century. It’s hard to think of a software application or service that does not have some fundamental dependency on database technologies. So it’s surprising that the digital preservation community seems to have spent so little time explicitly considering their preservation. More accurately it’s surprising…

Practical experiences with archiving PDF files This webinar deals with archiving PDF files. As PDF files in our repository have myriad data producers, the heterogeneity of PDF files is overwhelming. Unfortunately this means the creation of errors as well. Usually, the original data producers cannot be contacted any more, therefore we have to do the best we can with the PDF material. As we ingest PDF files and (almost no) PDF/A-files, the validation is done with JHOVE. JHOVE flags issues…

During March and April 2015 the OPF assumed stewardship of JHOVE after the existing maintainer, Gary McGath, expressed his wish to step down. The OPF’s initial aims were to take ownership of the JHOVE resources and establish sustainable home for the project on GitHub. Following this we’ve updated the build, testing and distribution process for the project. The webinar covers the work that the OPF’s done so far while showing prospective users and developers how they can obtain and use…

​Computational nature of digital media requires that we consider both the storage of software and content files and the computational environments in which they can be instantiated. ​In this webinar we will discuss the economic roots of digital obsolescence and the principles on which we can build sustainable services to access and process legacy digital assets. Such services are important to support preservation activities, including selection, characterization, and dissemination of digital assets. We illustrate the technical feasibility for achieving the…

As the digital preservation community is increasingly deploying tools into productive environments, the need to systematically evaluate and share evidence about the quality of these tools has become a pressing need. At the Benchmarking Forum at IPRES 2015, researchers, community organizations and practitioners discussed opportunities and challenges in adopting software benchmarking as a systematic tool for evaluating digital preservation tools. Outcomes include an initial set of benchmark specifications for targeted scenarios elaborated jointly during the workshop, and a set of…

Ingest more for less! An expensive part of ingesting digital collections into digital repositories is the quality assurance (QA) phase. Traditionally, data and metadata are quality assured before ingest, to ensure that only data which complies with the repository data formatting and documentation standards is preserved. This webinar will look at the Minimal Effort Approach from the Statsbiblioteket in Denmark. In Minimal Effort Ingest, we postpone the QA of data and metadata until after the data has been ingested and…

JHOVE is a great tool for validating content, such as PDFs, however much of the validation output given is difficult to understand. The aim of this online hack day is to enhance our knowledge about JHOVE errors – to create descriptions of errors and to identify example files, as well as to start to understand their preservation impact and what can possibly be done about them. How it Works We’ve tried to organise the day to make it as easy…
