5. Technical Aspects of the Transitional Process Mexico City, 11/12 Nov 2002 Data Manipulation Two temporary object (OldEnt and OldId) were created to import the data During the import an algorithm cleaned up the owner name and compared them between the 2 services objects. The cross relation was got from these information. Name clashes were treated by manual processing. The adopted transition schema provides only full whois and reverse publication services until the update of the information is made. Block boundaries were adjusted to prefixes. Represented reverse delegation on the Whois were adjusted to prefixes and represent exactly the requested reverse delegation.
