Data without Boundaries: A DDI-Based Metadata Model for Supporting Cross-National Data Discovery

Presenter 1
Arofan T Gregory
Metadata Technology North America

This presentation discusses the work of Data without Boundaries Work Package 8, exploring the requirements for a joint European-wide portal for the discovery of microdata held by statistical agencies and social science data archives across Europe. In support of this work, a survey of the various organization's metadata holdings has been explored, and work undertaken to produce a metadata model for implementation in Work Package 12. This metadata model will span both the Data Documentation Initiative for documentaing microdata and the Statistical Data and Metadata Exchange (SDMX) model for aggregate data holdings in the statistical offices. while European researchers may be familiar with the data holdings in their own national archives and statistical offices, they may not have as great a familiarity with holdings in other European countries.Aggregate data will be indexed and linked to microdata holdings to provide for improved discovery capabilities for European researchers. Similarities to the ongoing work on RDF expressions of SDMX and DDI are also explored.
