This paper will provide an overview of the longitudinal data processing protocols being implemented at the Australian Data Archive as part of the development of the ADA Longitudinal Archive. As part of the migration to a new storage foundation, ADA has been reviewing its longitudinal data holdings to streamline longitudinal data processing, particularly focussing on improvements to the metadata associated with these studies to take advantage of emerging discovery and visualisation tools. This paper will examine ADA's experience with this review process, experiences with the development of guidelines for data dictionaries and variable mapping systems, and the implementation of the procedures with 3 sample longitudinal studies within the ADA holdings. The paper will then conclude with a review of ADA's plans for documentation and support of future longitudinal and cross-sectional time-series data holdings, including new longitudinal panel studies, public opinion poll data and major cross-sectional social surveys. |
