This tool needs some explanation of how it came about. At Nationaal Archief we were faced with various bottlenecks at ingest for our digital repository (which we call e-Depot). Characterization was one of them and when the OPF released the first prototype of FIDO we happily jumped on board for its development. Seeing the potential […]

As I already briefly mentioned in a previous blog post, one of the objectives of the SCAPE project is to develop an architecture that will enable large scale characterisation of digital file objects. As a first step, we are evaluating existing characterisation tools. The overall aim of this work is twofold. First, we want to […]

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.

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 […]

As a part of the SCAPE project, I’m currently heavily involved in the evaluation of various file format identification tools. The overall aim of this work is to determine which tools are suitable candidates for inclusion in the SCAPE architecture. In addition, we’re also trying to get a better idea of each tool’s specific strengths […]
