Already a couple of weeks ago we had a hackathon in Cologne. Hospitality and location of the University of Cologne contributed a lot to the success of this event. Thanks to Manfred Thaller and Lisa Rau everything was perfectly organized. Thanks a lot Manfred and Lisa! With the experience of previous hack-events (the first OPF […]

There is a very first test available for a emulation based Word Perfect 6 to RTF file migration. A PLANETS web service running in Freiburg could be invoked by OPF partners running a PLANETS instance by adding an external resource. Just add the WSDL file of UfcMigrate The URL will change over the time […]

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 […]

I wonder if many people have had a chance to dig around in the latest signature release for DROID? There is an interesting format change that I think warrants some discussion. As I understand it, historically tif has been a problem for DROID based ID. Pronom has records for TIFF versions 3, 4, 5, and […]

The GRATE-R, originally developed for PLANETS, utilises the idea of performing migration by interactive session replaying in emulated original environments. According to this approach the format migration process is carried out by computer interaction with the graphical user interface of the original, format-native applications. Their capability of exporting the loaded digital objects in a format other than their initial format […]

In my previous post on formats, I ended up leaning towards a wait-and-see approach to format registry design. Unfortunately, I don’t really have that luxury. The SCAPE project needs to collect more format information to assist preservation planning and other processes. We even have some effort available to help build and/or fill a registry. But […]

Bill’s earlier post and this one from Chris Rusbridge have spurred me to try to describe what I discovered about PRONOM format records during my editable registry experiment. Building that site required a close inspection of the PRONOM Format Record data model, during which I realised that we commonly conflate two quite different ways of […]

Chris Rusbridge recently kicked off a discussion about where to find information about some old file formats – he was finding it very difficult to find what he needed. Readers of this blog might find his article interesting:

During the Planets project Paul Wheatley and I created the Planets Functional Model  . We identified in this model the functions that were related to the (OAIS) Preservation Planning activity, inspired by the experience gathered in the various Planets work packages. Central in the Planets model is the Preservation Watch Function. In this function […]
