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.

OK, not really the answers, just more questions!  But a few weeks back I sent round a draft of a registry guidelines document, asking for feedback.  I had included in that document a list of questions that we needed to consider and this post presents some of the answers I received, plus some answers I […]

I was recently re-reading a Planets project report from 2008, “Representation Information Registries” by Adrian Brown (PC/3-D7 if that means anything to you). It has a nice summary of the purpose of representation information registries that I thought was worth sharing: (extract in italics). Efficiency of description: Representation information forms a substantial element of the […]
