Thanks for progressing this! Having previously run a small wiki which was
spammed to death - and eventually having to shut it down I know from
personal experience the need is there!
A few random thoughts when I thought about similar things.
I naively think about http://wiki.foaf-project.org as being an agent of
sorts and the list of account on the wiki as a list of agents it "knows".
These agents in turn can say they "know" http://wiki.foaf-project.org . I
think the sematics of the above are not allowed in the current ontology this
directly but I would be tempted to add an rdf:about to each agent in
http://wiki.foaf-project.org/w/Special:F2F to the account page that each
user has on the wiki. In my case
http://wiki.foaf-project.org/w/User:Akbarhossain.com . I could then add an
entry into my foaf file to my account on the wiki. So
http://wiki.foaf-project.org say is "knows" my openid http:\\
akbarhossain.com and i say i know http://wiki.foaf-project.org in my foaf
file via my account http://wiki.foaf-project.org/w/User:Akbarhossain.com
I think ideally http://wiki.foaf-project.org/w/User:Akbarhossain.com would
have an entry saying it is a member of this group
I would also be tempted to add some entries into the
http://wiki.foaf-project.org/w/Special:F2F to express the ACL of the wiki.
I guess eventually I could see a scenario where perhaps openids you accept
for comments on your blog http://danbri.org/words/2009/12/29/523 are
members of the ACL with editing rights automatically for example.
