8/26 Laboratory executes an examination that produces digital data Laboratory pubblicates exam through the creation of an event and sends it to the system (in particular to the broker) Phisicians compile and sign reports and send them to the timestamp service Timestamp service appends a certificated datetime to the report and forwards it back to the phisician Phisician sends this signed document to the broker Laboratory decides to terminate the refertation process Clinical event is sent to the broker which shows it to the phisician
