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) *
