[Rivet] HepData and Rivet growing apart

[Andy Buckley]

Hi Holger,

Thanks for highlighting this again.

It's a disaster for Rivet if the data submitted to us in Rivet analyses 
does not align with that in HepData. HD should be our primary data 
resource, from which we can resync our data: I knew there was some 
divergence due to a few "hacked" ref data files, but this sounds like 
there has been a much greater break of synchronisation since the HD 
user-submission system was introduced.

Graeme, what do you suggest that we do? I hope we can also help you to 
identify and import analysis data that exists only in Rivet: this should 
not have happened, and please feed back to the experiments that the data 
repository is HD, not Rivet. I would be more than happy to co-sign.

Andy

PS. Holger, this reminds me: was the Rivet analyses json file for 
HepData ever created for the Rivet 2.5.4 release? Could you pull the 
scripts to generate that thing into the Rivet doc directory on the 
default branch, so people other than you can run it in future? Thanks.
