  • The Domain “Dataset Spec”: This global specification contains the static configuration information that “anchors” the process to a specific domain (e.g. “E3SM datasets”). This document (/p/user_pub/se3sme3sm/staging/resouceresource/dataset_spec.yaml) details the metadata that defines each (E3SM) dataset, experiment, model version(s), resolutions, realms, grids, frequencies, etc. By “walking” the branches of this document, the complete list of E3SM dataset_ids (as reflected in the ESGF “master_id”) may be generated. Subsets of these dataset_ids are passed as tokens to those processes intended to operate upon the corresponding datasets.

  • The Process “Transition Graph”: This global specification contains the transition rules that define the path(s) of conditional processing.
