Description
The National Archive of Computerized Data on Aging (NACDA) began working with DDI-Lifecycle in 2018. Since then, NACDA has made efforts to document in DDI-L some of our most established and frequently-used longitudinal data collections and display them on a Colectica Portal. In this presentation, I will discuss how the system of topical groups and subgroups we use to organize the conceptual variables in these data collections improves the interoperability and findability of the metadata on our portal, how the system has evolved over time, and our plans for its improvement and use in the future.
NACDA is part of the Inter-university Consortium for Political and Social Research (ICPSR) and based at the Institute for Social Research (ISR) at the University of Michigan.
