This webinar will focus on content profiling and preservation planning. It aims to address the following questions:
It will cover some of the tools that are available and there will be a demonstration of C3PO (Clever, Crafty, Content Profiling of Objects) tool, and an explanation of how you can analyse the metadata it produces.
Session Lead: Petar Petrov, Creative Pragmatics
Time: 13:00 BST / 14:00 CET
This Hackathon will provide participants with a chance to learn about what digital forensics has to offer to the digital preservation community by getting hands on with data, tools and new techniques. Our expert facilitators will be on hand to guide you through these challenging concepts and processes in a manner that is easy to understand and apply.
Part of my work on the SCAPE testbeds involves producing a workflow for the large scale migration of TIFF to JP2 files, with validation. The tests I have run all involve the lossy compression of files.
Two tools that could be used for the validation of image payload, and therefore success of a migration, are Matchbox, developed for SCAPE by AIT, and ImageMagick’s “compare” tool. One of Matchbox’s tests gives a result of SSIM, a value between 0 and 1. The metric I chose to use from “compare” was PSNR, a value in decibels.
As part of our work on test-beds for the SCAPE project we have been investigating the various ways in which a large scale file format migration workflow could be implemented. The underlying technologies chosen for the platform are Hadoop and Taverna. One of the aims of the SCAPE project is to allow the automatic generation and execution of Taverna workflows, which will be executed via Hadoop.
The four methods for implementing a file format migration workflow that we tested were:

The world of digital forensics offers many useful and practical techniques for capturing, understanding and preserving digital collections. This OPF Hackathon will provide participants with a chance to learn about what digital forensics has to offer to the digital preservation community by getting hands on with data, tools and new techniques. Our expert facilitators will be on hand to guide you through these challenging concepts and processes in a manner that is easy to understand and apply.
The first ANADP conference (http://educopia.org/events/ANADP), held in 2011 with participation by representatives from more than twenty countries, produced a broad agenda of forty-seven action areas for collaboration between national and international scale digital preservation efforts (this agenda, published in the ANADP volume, is available as a free download at the URL http://www

In 'Digital Preservation at your Command - Part I, attendees learned how to find content, create a checksum, identify files and create a basic manifest / profile. (The recording of this webinar can be seen here: http://openplanetsfoundation.org/opf-webinars-recordings).
Remote access to emulation, remote emulation and the emergence of a wide range of different cloud services, and end users interacting with them remotely through standardized (web-)client applications on their various devices offers the chance to combine both into an integrated access system to various obsolete computer environments. In order to provide a wide range of services, especially in combination with authentic performance and user-experience, a distributed system model and architecture is helpful.
System imaging - dumping the permanent storage of a computer system to re-run it in an emulator - is a viable option to preserve complete digital environments. These include complex digital artefacts, famous persons machines, electronic lab books of natural sciences research or software and hardware development environments of software companies, to mention just a few. These artefacts or complex environments - further on "preservation targets" - are typically customized for special purposes and often include highly customised configuration or (unique) user programming. Thus, they often cannot be easily migrated into a preservable format without risking the loss of significant information and/or the context provided by the look and feel and user interaction with the system.
