BSDIFF: Technological Solutions for Reversible Pre-conditioning of Complex Binary Objects

Documented provenance and the ability for researchers to locate and view original versions of digital records as transferred into an archive are concepts central to archival theory. The continuing ability to enable this is challenged by the numbers of digital records we’re facing; a requirement to follow good digital preservation practice; a need to provide access; the complexity of modern file formats; and the cost of doing all of it. Technological solutions, and techniques borrowed from other disciplines can help reduce costs throughout the transfer process through to the maintenance of digital objects in a digital repository without compromising the integrity asked by archival theory. Using binary diffs and binary patching mechanisms is one such solution that can reduce costs and provide a sound method of documenting all file modifications, from the trivial to the complex – enabling the original record to always be recovered.

The SCAPE Project video is out!

Do you want a quick intro to what SCAPE is all about?

Then you should watch the new SCAPE video!

The video will be used at coming SCAPE events like SCAPE demonstration days and workshops and it will be available on Vimeo for everyone to use. You can help us to disseminate this SCAPE video by tweeting using this link https://vimeo.com/99803729

 

Introducing Flint

Hi, this is my first blog post in which I want to introduce the project I am currently working on: Flint.

history

Flint (File/Format Lint) has developed out of DRMLint, a lightweight piece of Java software that makes use of different third party tools (Preflight, iText, Calibre, Jhove) to detect DRM in PDF-files and EPUBs. Since its initial release we have added validation of files against an institutional policy, making use of Johan’s pdfPolicyValidate work, restructured it to be modular and easily extendible, and found ourselves having developed a rather generic file format validation framework.  

SCAPE Demo Day at Statsbiblioteket

Statsbiblioteket (The State and University Library, Aarhus, hereafter called SB) welcomed a group of people from The Royal Library, The National Archives, and Danish e-Infrastructure Cooperation on June 25, 2014. They were invited for our SCAPE Demo day where some of SCAPE’s results and tools were presented. Bjarne S.
