NNPDF’s dataset naming convention

Each dataset implemented in NNPDF must have a unique name, which is a string constructed following this [Backus–Naur form]:

<valid set name> ::= <experiment> "_" <process> "_" <energy>
                   | <experiment> "_" <process> "_" <energy> "_" <extra_information>

<valid dataset name> ::= <set name> "_" <observable name>

<experiment> ::= "ATLAS" | "BCDMS" | "CDF" | "CHORUS" | "CMS" | "D0" | "DYE605" | "DYE866"
              | "DYE906" | "EMC" | "H1" | "HERA" | "LHCB" | "NMC" | "NNPDF" | "NUTEV" | "SLAC"
              | "ZEUS"

<process> ::= "1JET" | "2JET" | "CC" | "DY" | "INTEG" | "NC" | "PH" | "POS" | "SHP" | "SINGLETOP"
            | "TTBAR" | "WCHARM" | "WJ" | "WPWM" | "Z0" | "Z0J"

<energy> ::= <integer> <unit> | <integer> "P" <integer> <unit>  | "NOTFIXED"

<extra_information> ::= <string>
