The JPEG 2000 compression standard is steadily becoming more and more popular in the archival community. Several large (national) libraries are now using the JP2 format (which corresponds to Part 1 of the standard) as the master format in mass digitisation projects. However, some aspects of the JP2 file format are defined in ways that […]

Remote emulation has been a topic in digital preservation for a while. Several approaches to it have been explored and the feasibility of some stable prototype is pretty good. There are several different ways to achieve the separation into a server able to run the complex stuff and a rather simple client mostly limited to […]

After having emulators conceptually established in digital preservation and having proved to run them actually for different original environments, the next logical step is their preparation for main-stream. To deploy emulation in e.g. Migrate workflows is a bit more complex than to wrap a simple converter like ps2pdf but might earn a much wider covering […]

Emulators are a crucial building block in digital preservation strategies. They are supposed to bridge the widening gap between past and current digital environments. Like every other software they need to be updated from time to time if the actual environment they are running in changes. But, independent of those updates, the internal structures created […]
