There was a problem hiding this comment.
I like the idea, but I am wondering whether this can be made more generic on the podio side and put it together specifically for the event weights on the FCCAnalyses side?

Expose EventWeightNames metadata through podio::DataSource.
Store the weight names from the metadata frame and make them available to RDataFrame through the _EventWeightNames column.
This allows analyses to access event-weight labels without opening the input file separately.
