Group resources’ prefixes based on their part_of entries.


A dictionary with keys that appear as the values of Resource.part_of and whose values are lists of prefixes for resources that have the key as a value in its part_of field.


Many of the keys in this dictionary are valid Bioregistry prefixes, but this is not necessary. For example, ctd is one key that appears that explicitly has no prefix, since it corresponds to a resource and not a vocabulary.
