The current usage of DDI is heterogeneous. It varies over different versions of DDI, different grouping, and unequal interpretation of elements. Therefore, provider of services based on DDI implement complex database models for each developed application, resulting in high costs and application specific and non-reusable models. This paper shows a way to model the binding of DDI to applications in a way that it works independent of most version changes and interpretative differences in a standard like DDI without continuous reimplementation. Based on our DDI-FlatDB approach, shown first at EDDI 2015 & 2016, we present a complete implementation along the use case of a web-based questionnaire editor including sustainable solution for version management and efficient handling of large DDI structures. The user interface is adaptable to different usage scenarios to come. The application supports DDI-Lifecycle from the first question draft and hands over structured (meta-) data to survey institutes and data archives and supports the collaborative questionnaire development for the Pre-election Cross-Section of the German Longitudinal Election Study from early 2017 on.

“…While the formal specifications of DDI Lifecycle 3.1 and 3.2 are XML schemas, DDI content can be stored physically as an XML file, in an XML database, or even in a relational database. For a discussion of the latter see (Amin et al, 2011). The DDI Alliance is also currently working on two RDF vocabularies (Data Documentation Initiative.…”

“…While the aforementioned papers (see Amin et al 2011) focused on the usage of DDI in relational databases and were targeted more at the software developer community, this paper highlights the management considerations needed to choose the right infrastructure for different agencies. The following use cases provide illustrations to that end.…”
