DNSSEC: how are DS records supposed to be transferred and end up in parent zone?

My notes say that the hash is supposed to securely sent and stored in parent zone so what do I do after: dnssec-keygen -a RSASHA256 -b 1024 -n ZONE mydomain.net dnssec-keygen -a RSASHA256 -b 2048 -n ZONE -f KSK mydomain.net dnssec-signzone -g -o mydomain.net -N increment -k Kmydomain.net.+008+27724 mydomain.net.rev Kmydomain.net.+008+26646 dnssec-signzone -g -o mydomain.net -N increment -k Kmydomain.net.+008+27724 mydomain.net.fwd Kmydomain.net.+008+26646 is there a command or do I get in contact with the parent domain administrator and ask them to include it?
