py-llnl-sina (spack): Sina allows codes to store, query, and visualize their data through an easy-to-use Python API. Data that fits its recognized schema can be ingested into one or more supported backends. Sina's API is independent of backend and gives users the benefits of a database without requiring knowledge of one, allowing queries to be expressed in pure Python. Visualizations are also provided through Python. Sina is intended especially for use with run metadata, allowing users to easily and efficiently find simulation runs that match some criteria.
