Various audio mixers in the PLOUD Group have argued that the normal rules should indeed apply to IS too, as this makes for a simpler workflow and more predictable results. Where tools have no clear company owner, the tool name is used. Maurizio Montagnuolo RAI offers insight on supporting workflows on an advanced cloud media store.
