class pnpl.datasets.mixins.RadboudDownloadMixin[source]#

Mixin providing WebDAV-backed download from the Radboud Data Repository.

Classes using this mixin should define: - RADBOUD_DATASET_URL: str — full WebDAV URL of the dataset root,

e.g. "https://webdav.data.ru.nl/dccn/DSC_3011085.05_995_v1/".

Optional class-level overrides: - RADBOUD_USERNAME_ENV (default "RADBOUD_USERNAME") - RADBOUD_PASSWORD_ENV (default "RADBOUD_PASSWORD")

Expected instance attributes: - data_path: str — local directory; remote paths are mapped

relative to this.
