Why not help Hugo by showing Neo how to store the equivalent of the following XDb1 script in RM Sol#1 or #2 without redundant data.
color isa thing.
brown isa color.
person isa thing.
john isa person.
john's color is brown.
mary isa person.
mary's color is brown.
Although brown appears three times in the script, XDb1 normalizes the second two by making them references to the first one. There is only one brown in XDb1's db. Using RM#1 or #2, brown is stored three separate times. Received on Tue Jun 08 2004 - 05:21:14 CEST
