nomad-fsspec
An fsspec filesystem for the public raw data of NOMAD, the materials science repository. It is read-only.
import fsspec
fs = fsspec.filesystem("nomad") # https://nomad-lab.eu/prod/v1 by default
fs.ls("/") # public datasets
fs.ls("/wWgAnNZNQxOHLf97H62dgw") # the uploads of one dataset
fs.get_file(
"/wWgAnNZNQxOHLf97H62dgw/Xa2LB__ESiKu-odRBPJhjA/nomad-demo-data/BrK_svSe/TBCC006.ABC/vasprun.xml.relax2",
"vasprun.xml",
)
Paths are /<dataset id>/<upload id>/<path inside the upload>. Datasets and uploads have their
names in display_name. To use a NOMAD Oasis, pass base_url:
fs = fsspec.filesystem("nomad", base_url="https://my-oasis.example.org/nomad-oasis")
Only public data is listed. NOMAD's rate limits (HTTP 429 and 503) are retried.
