It is necessary to specify the objectives of SIS, certain elements of its technical architecture and its financing, to lay down rules concerning its end-to-end operation and use and to define responsibilities.
Is gá cuspóirí SIS, gnéithe áirithe den ailtireacht theicniúil a ghabhann leis agus den mhaoiniú ina leith a shonrú, rialacha a leagan síos maidir lena oibriú agus lena úsáid ó cheann go ceann agus a chuid freagrachtaí a shainiú.
