Data product revision (phase II)

Targets

Possible targets, to be discussed, include:

  • replacement of data structures:
    • old ROOT 3- and 4-vectors with new ones (possibly non-breaking change)
    • replacement of complex data structures with simple ones (std::array if supported by ROOT at the time we need it, std::vector, replacing std::set and std::map)
  • definition of a data augmentation protocol (e.g. with parallel collections)
    • development of viewing tools to push the structure behind the interface
  • reorganisation of data structures; candidates:
    • recob::Cluster: very heavy-weight, could be split by augmentation
    • recob::Track: needs redefinition
    • recob::Shower: it's a stub
