Hi Guys,

perhaps read the wiki-page in parallel to this email thread.
DOAP, FOAF, etc are all mentioned there already,

Benjamin, Ivan, you are free to edit the wiki page,
just change/adapt it so that it reflects your approach, please start 
(no edits so far,
this is a wiki, free speech, last change wins, anything goes, like

That was partly already there,
please edit the wiki page so that it reflects your exact ideas, but I 
think the current version already is like you say here.

ok, one more for SKOS

please add this to the wiki page!

they are rather buggy and not clear which one to use, but I would go for 
the simpler (not-timezone-as-datatype-one).

I also thought about this, but if you require from all participants to 
do that, it sucks.
Why should anyone annotate two types if one is enough? This is the 
format we expect external data to be in,
inference should add the additional triples.

SKOS covers this and more, so would rather use skos.
