message_ix_models.model.transport.material.get_groups

message_ix_models.model.transport.material.get_groups(config: Config) → dict[str, dict[str, list[str]]][source]

Return groups for a aggregate() operation on NTNU VMI data.

These include:

c (commodity) dimension: 1 or more original (NTNU VMI) commodity IDs aggregated to model.material commodity IDs.
t (technology) dimension: 1:1 from original (NTNU VMI) technology IDs to model.transport technology IDs. This effects rename and broadcast operations simultaneously.
