This comment is not specific to this PR but rather the extension of the existing code makes this shortcoming more clear:

This modules imports modules for MRIO sources and contains code forks - like IF statements - for handling specific sources as well. This means this module has to be updated each time a new source is being handled. This is not the best design.

We have code among the TIEM that can provide an example of a superior module design. See for instance FLOWSA's generateflowbyactivity.py. Code that is required to parse and further transform a specific source is put into a separate source module. Some of that is describing in this Wiki section.

Files here such as ceda_helpers.py and the yaml configs partially implement but do not fully implement this option. I would recommend further refactoring to mature the code to eliminate specific MRIO imports and code forks from this file.
