A small portion of the implied metadata is...
[T_Tables]
Table
T_Gender T_Person T_Tables T_Columns [T_Columns] Table Column
--------- ------
T_Gender ID T_Gender Name T_Person ID T_Person Name T_Person Gender T_Tables Table T_Columns Table T_Columns Column
As for your desire of finding a rule Neo, simply conducting an observation of X in isolation can not determine if X is meta data or not. However if its context is considered you will be much better placed to have a wild guess! Cheers, Frank. Received on Fri Mar 04 2005 - 12:44:11 CET
