Currently the model runs are output as a list in the share/dataset_lists directory:

We would like to use the suite_id as a unique identifier for each section, in order to later use this in parameterising the model runs through CDDS:

Future Naomi Parsons (@NParsonsMO) if you pick this up, you already did it:

import yaml
import os

current = os.path.expanduser('~/cylc-run/CMEW/run7/share/dataset_lists/model_runs.yml')
suite_facet = 'suite_id'

def use_facet_as_key(key, filepath):
    with open(filepath, 'r') as f:
        data = yaml.safe_load(f)

    new_dict = {}
    for section in data:
        unique = section[key]
        new_dict[unique] = section

    with open(filepath, 'w') as f:
        yaml.dump(new_dict, f)

use_facet_as_key(suite_facet, current)
