[Data-modeling] None as a topic

[Jameson O'Guinn]

There has been a pretty intense debate over the status of the "none"  
topic in the past week. I would like to see what the data modeling  
community proposes as the best answer. The discussion can be found here:

http://www.freebase.com/discuss/threads/guid/9202a8c04000641f8000000005c7ab84

So far the solutions discussed have been: 1) keep the topic "none" as  
is; 2) delete the topic "none"; 3) make "none" a reserved word or a  
non-linked property (like an integer).

Let me know if this isn't the place for this discussion.

Thanks,
Jameson
