The International Solar-Terrestrial Physics (ISTP) Metadata Guidelines for describing the internal meaning of self-describing scientific data formats, such as CDF and netCDF in Heliophysics. A dataset using the ISTP Guidelines forms a logically complete and self-sufficient whole (data and descriptions). The Guidelines describe the required, recommended, and optional types of metadata that provide a definitive description of the data in each variable and the dataset as a whole. The goal is to make each scientific dataset correctly and independently usable and accessible by the science community into the future, and to enable analysis and display by generalized software applications such as CDAWeb, Autoplot, SpacePy, and PySPEDAS/SPEDAS. Using a common set of metadata also enables cross-comparison of different datasets.

Attributes describing the whole dataset and individual files in the dataset.

Definitions and examples of data, support_data, and metadata variables, including their dimensionalities and what is needed for their correct display.

Attributes describing individual variables and relationships between variables.

Valid values for DICT_KEY variable attribute describing variable quantity kind.

Examples of instrument-specific skeleton tables. Use ISTP Metadata Editor web application for creating skeleton tables and skeleton CDFs (structure and metadata, but no data).

Dataset creation best practices, including CDF and netCDF specific. Tools for creating data CDFs by merging data with skeleton CDFs.
