Jack,

Head down on a number of drafts but there is one point on FOL that I 
think is important:

Topic maps not "missing" an FOL engine. Unlike CGs, you get a choice.

The Topic Maps Reference Model (TMRM) allows you to disclose whatever 
inferencing that you wish to use, FOL if that is your choice but others 
as well. In other words, the TMRM allows your choice of inferencing 
systems or engines and for that choice and its rules to be disclosed.

Some people will find FOL useful, others will prefer other systems or 
perhaps even wish to be deliberately illogical. There is no basis on 
which to assume any inferencing system will be deemed equally adequate 
by all users. So long as the system and it rules are disclosed, the TMRM 
is perfectly content.

Note that your choice of inferencing, under the TMRM, can be part of the 
topic map, so there is no need for a separate step.

Hope you are having a great day!

Patrick
