OK. I took "dividing an article into subtopics" as "dividing an
article into parts". I think there's ways that "subtopics" could be
parts, and ways that "subtopics" could be members of a category.
I'd say there's a part-whole relationship if:
* There's an implied ordering of parts. For example, [[US
history]] might have parts like [[US history before 1604]],
[[US history 1604-1775]], [[US history 1776-1783]], etc.
Contrast [[History of jazz in the US]], [[History of women in
the US]], [[History of baseball in the US]]. These might all be
members of a _category_ [[US history]], but there's not the
same kind of implied ordering.
* There's the one-parent tree structure as mentioned before.
I think we can do interesting things with part-whole
relationships. Automated Next, Prev, and Up links might be useful, and
an option to read or download or print the whole shebang (container
article plus parts) would be neat, too.
Anyways, I've been thinking about parts, as you can tell.
