Hardware emulators are software implementations of (past) computer architectures to reproduce original environments for a wide range of purposes. Most emulators and virtual machines are programmed for local access, which means that they are installed on the machine the user is working on.
The next OPF Hackathon - A Practical Approach to Preservation Systems - will focus on preservation workflows and systems. It will consider a large number of widely available tools that are being used both by the community and in industry.
Automated identification of corresponding images and duplicate removal is a challenging task due to inconsistent quality of digitized book collections. Validating such collections based on qualitative criteria is a challenging endeavor according to the sheer amount of data that has to be processed. Traditional approaches seem to have peaked at a certain level.
In this blog post I will give a brief update of the latest jpylyzer developments. Jpylyzer is a validation and feature extraction tool for the JP2 (JPEG 2000 Part 1) still image format.

FIDO (Format Identification for Digital Objects) is a Python command line tool to identify the file formats of digital objects. A lot of improvements to the code and functionality have been made.
Early in the SCAPE project we have been looking at how to make the project results more sustainable overtime. One way of achieving this is to increase software adoption. A critical mass of users will most likely provide valuable feedback to developers to make the software better and help sustain the software as some of these users will be developers themselves.
Many institutions have been doing large scale digitisation projects during the last decade, and the question how to store the digital master images in a cost effective way made the JPEG2000 image format more popular in the library, museums, and archives community. Especially the lossy JP2 encoding of page image masters turned out to provide a good balance between reducing the file size and preserving the visible properties of a master image.
This will be my shortest blog post ever. Following up on my previous blog post on a prototype JP2 validator and properties extractor (jpylyzer), there is now a comprehensive User Manual of the tool. Just follow the link below and get the PDF file that is listed under 'Download Packages':
Archives New Zealand and the University of Freiburg are cooperating on a data recovery project. The archive received a set of 5.25 inch floppy disks from the early 1990s that contained records of a public organization dating back to the mid 1980s. These floppies were not readable in standard X86 machines with a 5,25 inch floppy drive attached to it.
