The data portal DDI on Rails accompanies researchers throughout the entire course of their research projects from conception to publication/citation.
The system offers researchers the possibility to explore the data, to compile personalized datasets, and to publish results on the publication database.
In contrast to similar products, DDI on Rails is study-independent and open-source, is able to document data with multiple versions/distributions and the specific characteristics of a longitudinal study, and is easy to use.
The project was initiated by Marcel Hebing during his time at DIW Berlin, as part of his PhD thesis A Metadata-Driven Approach to Panel Data Management and its Application in DDI on Rails.
Today, the German Socio-Economic Panel (SOEP) continues the development auf DDI on Rails, which is used for their metadata-service paneldata.org.
The source code is available on Github.
