The method assumes that the first index is the name of the stressor/impact/input type. To provide a consistent naming this is renamed to ‘indicator’ if they differ. All other index names (‘compartments’, …) are added to the concatenated extensions and set to NaN for missing values.

Notes

Attributes which are not DataFrames will be set to None if they differ between the extensions
