@dc-almeida & @phackstock, can you please check whether this is an issue in nomenclature?

[phackstock]

I'll take a look, my hunch is that we currently don't support substitution of multiple different tags in the same variable.

[orichters]

For the variables it works even with multiple tags, but not for the description, even if there is only one single tag:

• "Use of {Secondary Fuel} for carbon management by production of biochar using pyrolysis"
• "Use of {Secondary Fuel} for carbon management by direct air capture"
• "Use of {Secondary Fuel} for carbon management by electrochemical separation of dissolved inorganic carbon from seawater"

etc.

[orichters]

I think I got the problem. It is the use of a tag in the description that is not present in the variable name as well, see here: https://github.com/IAMconsortium/common-definitions/blob/258c943fdbc16f362865367dba68daba50bcac93/definitions/variable/energy/final-energy.yaml#L120-L125

Thanks for checking @orichters, I think we have to indeed open a nomenclature issue for that one.

[orichters]

In the sense that these errors are identified in the tests?

[phackstock]

Ah never mind, the tag replacement logic of nomenclature is sound after all. What we could check for is that all tags used in a variable need to occur in the name of the variable.

[phackstock]

Closing this issue as the non-replacement of the tags is expected and intended. If we would replace tags within a definitions that are not part of the name, we'd get duplicates.
