[foaf-protocols] Person <-> Group (+sub/related groups) relations...

I work more and more with sites for online communities, recently I look how to take advantage of FOAF for representing structure of membership in groups and subgroups plus relation between groups/sub.
Looking at it from perspective of seeing various profiles, in a group profile it seams easy to include list of participants with foaf:member property of a group. But other scenarios I see getting more complicated:
On profile page of a person I would like to include list of groups this person participates in. In the mailing list archives I came across two mails talking on this topic (guessing could find more digging deeper...)
where Dan Brickley proposes solution like:
</foaf:Person> (typo: s/Person/Group)
plus RDFa XHTML exmaples
IMHO stating membership in lets say 100 groups may look quite awkward using this pattern, but machine shouldn't care much ;)
in second mail: http://markmail.org/message/jjm5x4y4tbdc5eom?q=foaf+group+person&page=3#query:foaf%20group%20person+page:3+mid:jjm5x4y4tbdc5eom+state:results
Henry Story suggests:
"Why not just use foaf:member ? In N3 and rdfa writing the inverse relation is
easy. In N3 it is
person is foaf:member of group .
in rdf you use the rev= attribute. Better use these syntactic tricks that keep
inventing inverse relations for everything."
I couldn't find wiki page clarifying this issue, if it doesn't exist I would like to help with creating one...
Going further how could I state relations between groups? Very often in group profile it has related groups and subgroups as for example this one (sidebar): https://n-1.cc/pg/groups/7826/lorea/
Once more I would like to later on help with updating wiki with clarifications I hope for posting this question.
Thanks a bunch!
