Earlier this week the National Archives of the Netherlands (NANeth) published a report on preferred file formats. It gives an overview of NANeth’s ‘preferred’ and ‘acceptable’ formats for 9 content categories, and also explains the reasoning behind the selected formats.

In this Blogpost I want to examine the findings of two validation tools, JHOVE (Version 1.14.6) and Bad Peggy (version 2.0), which scans image files for damages, using the Java Image IO library. Goal is to compare the findings and enable the reader to know what to expect from these validation tools for the daily […]
