Following up on the idea of system imaging or "snapshotting" discussed in a previous post and presented at this year’s iPRES 2011, a general concept of long-term sustainable computer systems could emerge. Why not take emulation into consideration when designing future systems and defining their requirements? A seamless process would allow for systems that were […]

 Many office suites and other applications allow the embedding of information in them via a link to another file. The use of linked spreadsheets is common amonst data intensive agencies and large documents are often managed through linking multiple office documents to form a single final product.  Currently we have only anecdotal evidence as to […]

The typical reading room computer in libraries, archives and often museums is equipped with a way for patrons to search and browse the institutions catalogues and digital collections. The digital collections are often rather restricted by the systems to making accessible only a few of today’s multimedia formats and documents types (for example PDF, jpeg […]

Emulation requires disk images to be provided and used for the main hard drive of emulated computers. These disk images can be captured from old hard drives as discussed here. In order to automate aspects of running these disk images in an emulator a tool is needed that tells us which emulators would be compatible with […]

This tool needs some explanation of how it came about. At Nationaal Archief we were faced with various bottlenecks at ingest for our digital repository (which we call e-Depot). Characterization was one of them and when the OPF released the first prototype of FIDO we happily jumped on board for its development. Seeing the potential […]

Emulation services for direct user access often require more effort than simply providing the appropriate emulator and system image. Usually, the average visitor to memory institutions is not familiar with past computer architectures and their operating function. Thus, our goal is to research different approaches to creating automated access to the different digital artefacts users […]

The new FIDO (Format Identification for Digital Objects) is here, version 0.9.6. Improvements: reports if match is based on signature, extension or no match (fail) reports if file is empty (to stderr) reporting of mime-types fixed (special thanks to Derek Higgins) shows help upon invocation without arguments PDF signatures updated from PRONOM files, due to […]

As I already briefly mentioned in a previous blog post, one of the objectives of the SCAPE project is to develop an architecture that will enable large scale characterisation of digital file objects. As a first step, we are evaluating existing characterisation tools. The overall aim of this work is twofold. First, we want to […]

Over the last few weeks I’ve been working on the design of a workflow that the KB is planning to use for the migration of a collection of (mostly old) TIFF images to JP2. One major risk of such a migration is that hardware failures during the migration process may result in corrupted images. For […]
