<https://projectredcap.org>, Harris, et al. (2009) <doi:10.1016/j.jbi.2008.08.010>,
Harris, et al. (2019) <doi:10.1016/j.jbi.2019.103208>) is
a web application for building and managing online surveys and databases
developed at Vanderbilt University. The API allows users to access data
and project meta data (such as the data dictionary) from the web
programmatically. The 'redcapAPI' package facilitates the process of
accessing data with options to prepare an analysis-ready data set
consistent with the definitions in a database's data dictionary.
