At EDDI 15 and 16 we presented a flexible way for storing metadata structured with DDI called DDI-FlatDB on the use cases of a questionnaire editor. Within the last months, we were faced with DDI 3.2 remodelling of the metadata exported from the GESIS data catalogue (DBK). As DDI 3.2 will be the GESIS wide standard, we had to adopt this export, especially for the study level documentation from the DBK. We will present, how the data catalogue DDI structure is actually expressed in DDI 3.2, how this affects the splitting into XML snippets and how this changed the consumption of these snippets in our frontend solutions. The main feature of DDI-FlatDB, fast adaptation of new DDI formats, still holds and we didn't need to change any code in the Questionnaire editor to adopt the new DDI standard. In addition, we will present our experience with a use case from the border areas of DDI reusing DDI-FlatDB. We adopted the principle to support the management of controlled vocabularies for the CESSDA CV-Manager. In a short amount of time we were able to create a prototype, which structures its data according to SKOS with very few extensions.
