Evaluation of DDI 3 - Preservation metadata (D8.1)

This document discusses the scenarios that will evaluate the DDI standard version 3 established to document comparative social science surveys. The bottom up approach describes four use case scenarios used for the testing of DDI 3. The example from the ISSP cross-national study research program provides the material for usage with the evaluation of the first use case to assess involved modules of the DDI standard related to the space dimension. Further bottom up uses cases are outlined for the most complex dimension space x time. The top down approach introduced in this version covers use cases starting with the grouping approach. Some critical aspects on use of the top level modules group / schemes and / or comparison / resource package require further examination and discussion in the new CESSDA organisation and within the DDI Alliance itself.
