Project History

The first MISSY project started in 2003. Several projects, funded by different public institutions such as the BMBF (Federal Ministry of Education and Research) and the DFG (German Research Foundation), helped to improve the accessibility of documentation of official microdata and related services continuously. The following sections contain a short description of the development of MISSY so far.
