bw2io.strategies.ecospold2.es2_assign_only_product_with_amount_as_reference_product(db)[source]#

If a multioutput process has one product with a non-zero amount, this function assigns that product as the reference product. This is typically called after remove_zero_amount_coproducts, which will delete the zero-amount coproducts. However, the zero-amount logic is still kept in case users want to keep all coproducts.

Parameters#

dblist

A list of datasets, where each dataset is a dictionary containing an ‘exchanges’ key with a list of exchange dictionaries. The structure of a dataset is as follows:

{

“exchanges”: [

{: “type”: “production”, “amount”: float, “name”: str, “flow”: str, “unit”: str,

]

}

Returns#

list: The updated list of datasets with the non-zero amount product assigned as the reference product for multioutput processes.

bw2io.strategies.ecospold2.remove_unnamed_parameters(db)[source]#

Iterate through datasets in the given database and remove unnamed parameters from the ‘parameters’ dictionary of each dataset. Unnamed parameters can’t be used in formulas or referenced.

Parameters#

dblist

{

“parameters”: {: “parameter_name”: {“value”: parameter_value, “unnamed”: boolean}, …

}

Returns#

list: Updated list of datasets with unnamed parameters removed from the ‘parameters’ dictionary.

bw2io.strategies.ecospold2.update_social_flows_in_older_consequential(db, biosphere_db)[source]#

Update the UUIDs of specific biosphere flows with the category ‘social’ in older consequential datasets. These flows are not used, and their UUIDs change with each release. The ecoinvent centre recommends dropping them, but this function replaces their UUIDs instead.

Parameters#

dblist: A list of datasets, where each dataset is a dictionary containing an ‘exchanges’ key with a list of exchange dictionaries. These datasets represent the main data to be updated.
biosphere_dblist: A list of biosphere datasets, where each dataset is a dictionary containing flow information. These datasets provide the updated UUIDs for the specific social flows.

Returns#

list: The updated list of datasets with the UUIDs of the specified social flows replaced.

Examples#

>>> db = [
...     {
...         "exchanges": [
...             {
...                 "name": "residual wood, dry",
...                 "input": "old_uuid",
...             },
...         ],
...     },
... ]
>>> biosphere_db = [
...     {
...         "name": "residual wood, dry",
...         "key": "new_uuid",
...     },
... ]

[
    {
        "exchanges": [
            {
                "name": "residual wood, dry",
