The Dataverse is an open source web application to share, preserve, cite, explore and analyze research data. It facilitates making data available to others, and allows you to replicate others work. Researchers, data authors, publishers, data distributors, and affiliated institutions all receive appropriate credit.
A Dataverse repository hosts multiple dataverses. Each dataverse contains datatset or other dataverses, and each dataset contains descriptive metadata and data files (including documentation and code that accompany the data).
