MIXED is a project of DANS, Data Archiving and Networked Services. MIXED is to contribute to digital preservation, by dealing with the problem of file formats. Over time, file formats become obsolete. When that happens, the information in such file types is no longer accessible. MIXED follows the strategy of converting files to XML as soon as possible, preferably when data is ingested into the archive. MIXED also converts these XML files to formats of choice by the archive user.
