The SCAPE project is focussed on large scale digital preservation, to be able to manage large scale collections then it is important to work within a policy framework. Developing policy in a new and changing area can be hard and so the SCAPE Policy Representation team have worked on creating a three tier policy framework, a catalogue of policy elements which can be used by organisations as a starting point for creating their own preservation procedure policy. SCAPE has produced…

26 Jun

Overview An important part of digital preservation is analysing content to uncover the risks that hinder its preservation. This analysis entails answering diverse questions, for example: Which file formats do I have? Are there any invalid files? Are there any files violating my defined policies?; and many others. The threats to preserving content come from many distinct domains, from technological to organizational, economical and political, and can relate to the content holder, the producers or to the target communities to…

Overview This webinar looked at the techniques the National Archives New Zealand is developing to aid in the analysis of collections and also support the dissemination of the skill set that will help non-digital-preservation specialists continue to support the organisation in its ability to process born-digital collections. In 2013, the Archives New Zealand’s worked on analysing the content of a recent Royal Commission. It brought them to the conclusion that a different approach was needed to analyse digital content that could potentially be…

20 May

Overview For decades memory institutions have put effort into dealing with pieces of the digital preservation puzzle. Unfortunately this has also resulted in quite a lot of fragmentation – solutions in place in different institutions and countries are not easily reusable in others. After carrying out extensive consultations with the European Commission a set of institutions (including OPF members: the Danish and Estonian National Archives) secured funding for a project which tackles the standardisation of the core interoperability aspects for…

29 May

This one-day workshop examined how digital forensics and the use of disk images can support your digital preservation workflows.

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…

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…

This webinar presents the Outer OAIS-Inner OAIS (OO-IO) Model, which is a model building on OAIS allowing different functional entities to be shared among archives. This is especially used in Distributed Digital Preservation (DDP) which is crucial for various parts of digital preservation, but is not covered in detail in the OAIS reference model. Here distributed digital preservation is “the use of replication, independence, and coordination to address the known threats to digital content through time to ensure their accessibility”.…

Many libraries, archives and museums (LAMs) have been creating disk images of media in their care, but they’ve previously had few options for providing access to the materials on those disk images. The BitCurator Access Webtools, created through a grant from the Andrew W. Mellon Foundation, allow users to browse file systems contained within disk images using a web browser. It is intended to support access requirements in libraries, archives, and museums preserving born-digital materials extracted from source media as…
