An abattoir that kills sheep must give the Food Authority written details of how it will tell lamb from hogget meat: the identification method, where in the process the call is made, how the identification is applied and how it is kept until the lamb or hogget brand goes on. It may not use the system until the Authority is satisfied it will work and be maintained and approves it, may not alter it without approval, and must produce animals, carcases, meat and records whenever an authorised officer needs them to monitor the system.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
