REDCap and DDI Exporting Data and Metadata with the API

The REDCap (Research Electronic Data Capture) consortium is a group of over 450 institutions that supports a web application which supports data capture for research studies (see http://project-redcap.org/). The application allows interactive survey instrument development and data collection. Data and scripts for SPSS, SAS and R can be exported from REDCap. Survey metadata including question text and flow control can be also exported as a csv file. This paper describes code in the R language to convert the REDCap survey metadata from csv to DDI 3.1. It includes a discussion of which REDCap instrument attributes can be represented by DDI 3.1 elements other than Note. This presentation includes information on the REDCap API and metadata about mapping data entry forms to events in a longitudinal study.
