Practical Implementations of the DDILimDAS Results at the GESIS Data Archive

So far, different DDI formats have been used at the GESIS Data Archive.  The aim of the project DDILimDAS was to create a common metadata schema in DDI Lifecycle format to promote interoperability of metadata between several GESIS applications. The DDI 3.2 mappings were introduced last year at EDDI 2016. The presentation this year will show for the example of four of those GESIS applications how they implemented our DDI Lifecycle mapping recommendations of the DDILimDAS project. These metadata tools, which are in use for the purposes of documenting data holdings on study and variable level, are da|ra, DBK, EQB, and QMD.

The da|ra registration agency has recently updated its metadata schema and will introduce the new version 4.0 in December 2017. The Data Catalogue DBK uses the DDI-L mapping to provide study descriptions in DDI 3.2 format (download and OAI-PMH). Both systems contain documentation on the study level. Examples for metadata on variable level will be presented with the CESSDA Euro Question Base (EQB) project that implements an initial version of the CESSDA metadata portfolio and the Questionnaire Management and Documentation (QMD) project providing a DDI 3.2 questionnaire editor, used in a first stage for the German GLES election study.
