SDNist (v1.3) is a set of benchmark data and metrics for the evaluation of synthetic data generators on structured tabular data. This version (1.3) reproduces the challenge environment from Sprints 2 and 3 of the Temporal Map Challenge. These benchmarks are distributed as a simple open-source python package to allow standardized and reproducible comparison of synthetic generator models on real world data and use cases. These data and metrics were developed for and vetted through the NIST PSCR Differential Privacy Temporal Map Challenge, where the evaluation tools, k-marginal and Higher Order Conjunction, proved effective in distinguishing competing models in the competition environment.

SDNist is available via `pip` install: `pip install sdnist==1.2.8` for Python >=3.6 or on the [USNIST/Github](https://github.com/usnistgov/Differential-Privacy-Temporal-Map-Challenge-assets/).

The sdnist Python module will download data from NIST as necessary, and users are not required to download data manually.
