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.
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.
My last post discussed the benefits of collabaration, centred around a SCAPE hackathon. I argued that, in general, it was the collaborative, collocated nature of the developers working together that made demo development quicker; more people staring at the same problem results in multiple and varied viewpoints, ideas, and solutions.

I have attached a basic introduction to writing format signatures - this written to assist new colleagues, or anyone new to the idea of writing basic signatures for the PRONOM /use with DROID.
I hope that you find it useful, and if I've made any blunders please let me know!
Following on from the interesting discussion in my last post about the jpeg signatures, I undertook some quick testing on the impact of using / not using the EOF sections of a DROID signature file.
I previously posted this signature file here: http://dl.dropbox.com/u/59534857/DROID_SignatureFile_V55%20-%20no%20EOF....
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':
A few months ago I wrote a blog post on a simple JP2 file structure checker. This led to some interesting online discussions on JP2 validation. Some people asked me about the feasibility of expanding the tool to a full-fledged JP2 validator. Despite some initial reservations, I eventually decided to dedicate a couple of weeks to writing a rough prototype.
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.
The draft programme for Future Perfect 2012 is now available online!
The theme of Future Perfect 2012 - Digital Preservation by Design - seeks to stimulate discussion about how, when and why influencing the design of systems can support digital preservation and ultimately ensure that today’s information is available tomorrow. Future Perfect 2012 will be a two day conference featuring many exciting international speakers.
Our audience will hear presentations from:
