[Rivet] [HepData] Question about format plain input

[Andy Buckley]

Thanks Graeme,

There is already the option of such a "mapping", I think, in that the 
name/path of a histogram in Rivet isn't tied to the variable name.

You can organise the storage of histogram pointers in whichever way is 
most convenient (arrays of pointers combined with a for loop over the 
indices being a convenient way to implement analyses where e.g. the same 
observables are computed for several different particle or event 
selections).

Using the HepData IDs rather than rewriting the .yoda file is strongly 
recommended -- and should be essential for any analyses submitted to us 
-- because otherwise keeping the reference data up to date 
"automatically" will be impossible.

Cheers,
Andy
