Algorithm 3. DataPublicationOperation().

Input:

  op_type; name, ttl, type, rdata_sets; rrsig, prev_txn

Output:

  DomainTxn

1: DomainTxn.OperationType == op_type

2: DomainTxn.PrevTxn == prev_txn

3: if op_type == publication then

4:  DomainTxn.NAME = name

5:  DomainTxn.TTL = ttl

6:  DomainTxn.TYPE = type

7: end if

8: DomainTxn.RDATA = rdata_sets

9: DomainTxn.RRSIG = rrsig

10: if op_type == deletion then

11:  DomainTxn.NAME =∅

12: end if

13: DomainTxn.TimeStamp = CurrentTime()

14: DomainTxn.Signature = GenSig()

15: return DomainTxn
