As the Consortium has grown, so has the sophistication and influence of our Consortium partners. Experts in informatics, biostatistics, data warehousing, clinical systems, trial operations, standards and ontologies, security methods, computer science, global health, mobile systems, library science, and other domains participate in the consortium and consult with the development team as needed. Our increasing international partner base in resource-limited areas has prompted our teams to build a REDCap mobile app to allow offline data collection when internet connectivity is not present. The growth of the REDCap Consortium and user base has created opportunities to collaborate with other consortia (e.g., PhenX [52,53], Medical Data Models [54], BioPortal [55], PROMIS [56]) to integrate standardized terminologies and instruments. Portability of project metadata across REDCap installations has allowed new types of sharing and collaboration. During the Ebola outbreak in 2014, we saw a rapid mobilization of REDCap partner sites sharing methods for surveillance data collection in both academia and state governments, setting the stage for additional attention and adoption across U.S. state health departments, the U.S. Department of Veterans Affairs and other government
