Servicetypename Preservation action service
Description For any digital collection there will be a certain point in time that action is required to retain it accessible for users. Technically speaking, this means that file formats need to be converted (file format migration) or that the originally used computer platform is recreated (emulation).

These two actions should be made available as services (on site of remotely) to facilitate batch conversion of data or on demand conversion or emulation.

Implementations Emulation Framework (EF) Supports the user in recreating an authentic computer environment using emulation. The EF automates almost all steps from object identification until compiling and configuring the emulated environment. It uses existing well known emulators such as QEMU and Dioscuri. The basic set of supported environments consist of x86, C64, Amiga, BBC Micro, Thomson and Amstrad, but this set can be extended. The EF comes with a Software archive web service and an Emulator archive web service to preserve emulators and software centrally in an organisation or across the internet.


MIXED (Migration to Intermediate XML for Electronic Data) is a service that can convert files with tabular data (spreadsheets and databases) to supplier independent XML for long term preservation. This is the so called Standard Data Format for Preservation (SDFP). MIXED does not store the converted files, but returns them to you for download and keep 'for ever'. A SDFP file can also be converted back by MIXED to the original supplier dependent format, or to formats of other suppliers, or - in the future - to not yet existing formats.


  • Further extend the EF with broader support of emulated platforms and software
  • Further extend MIXED
  • Lobby at EU for a change in the legal framework to allow reuse of old software and emulated hardware without charge
  • Lobby at software/hardware vendors to allow the reuse of their software/hardware for preservation purposes.

Finaldestination One or more operational preservation action services (migration, emulation) which can be used for access to digital collections and for validation of digital objects.
