Dataverse is an open source data repository platform developed by the Institute for Quantitative Social Science at Harvard University (with contributors and adopters from all around the world). Dataverse supports researchers with open and mediated data publishing, sharing, research promotion, and the reuse of others’ data. The Dataverse platform makes it easy to deposit and publish research data; however, often deposited research data require additional preparation and curation to be ready for meaningful reuse. Data require accurate and rich documentation and metadata—without them, data are meaningless. Standard metadata, such as DDI, are useful for describing data in Dataverse. This presentation will demonstrate how Dataverse supports the creation of metadata for improved data discovery, access and reuse, and the preservation of research data in Dataverse.
