Includes a metadata system with column types and\nprimary keys, declarative constraints enforced via rejection\nsampling, conditional sampling, and quality, validity and\nprivacy reports modeled on those of the 'SDMetrics' library.\nInspired by the Python 'SDV' (Synthetic Data Vault) library by\n'DataCebo'; see Patki, Wedge and Veeramachaneni (2016) \"The\nSynthetic Data Vault\" .", "License":
