Hi Karl,

I briefly reviewed the Groups documentation and I have the following 
comments (below each excerpt, in bold).


      "Special Values

Group 9.0, Unknown, has a special meaning. Individuals are placed in 
this group by Interpolation 
<http://papio.biology.duke.edu/babase_system_html/ch04s06.html> when an 
their whereabouts are unknown. Another group code for unknown 
whereabouts should not be created."

*Typo above in red.*


        "From_group

The Gid 
<http://papio.biology.duke.edu/babase_system_html/ch03s01.html#Groups-Gid> 
of the group from which this group split off. This column may be NULL, 
depending on the value of the Permanent 
<http://papio.biology.duke.edu/babase_system_html/ch03s01.html#Groups-Permanent> 
column."

*I don't intuitively understand how the Permanent column might change 
the Gid value.  Can it be briefly explained?*


        "Permanent

This column indicates whether the group is a permanent group or not. The 
value TRUE in this column means that the group is permanent, the value 
FALSE means the group is temporary. This column may not be NULL."

*Is there a formal definition of permanent versus temporary as it is 
used regarding groups?  The distinction would probably be helpful to 
babase users.*

*
Why are there no links to the From_group definition? (gid, permanent, 
supergroup all have links to a definition) *
