The dataregistry package
The tutorials for the dataregistry package come in the form of Jupyter
Notebooks (hosted in the docs/source/tutorial_notebooks directory in the
repository).
The tutorial notebooks can be run interactively at NERSC (see here for more info), or serve as standalone reference material by viewing the notebooks on GitHub.
See also some simple examples of queries and dataset registration here <usage> which you may be able to adapt to your needs.
