Fundamentals:Principle of Unique ID
From TraceFood
To achieve referential integrity and true traceability, TraceFood requires globally unique identification of each trade unit.
In order to achieve referential integrity and true traceability, the TraceFood Framework requires that the traceable units shall be uniquely identified. Furthermore it requires that a minimum of additional information shall be linked to the traceable units throughout their lifetime. Later on these data may be accessed via the unique identification number. Common practice for creation of the smallest traceable unit varies in different industries.
To see how this can be done in practice, see the section on unique identification in the good traceability practice section.
