I think this could all be simplified into a single rule. rel="me"
with an hCard at either end is a legitimate mechanism to connect all
XFN relationships on both pages to the single hCard. I see no reason
to create a rule that the hCard must be on the same page (#1), only to
immediately create an exception to that rule. Putting the hCard on
the same page is one way to connect it to the XFN relationships, but I
see no reason to prefer it over the alternatives for accomplishing the
same goal, e.g. linking to an hCard on another page with rel="me". If
anything, I think the latter method should be preferred, following the
DRY (Don't Repeat Yourself) principle. So that would leave us with #2
and #3, which are just discussing both ends of XFN relationships. So
I'd boil this all down into one simple rule:
1. All people in an XFNetwork MUST be identified via hCard somewhere
within the network.
My MetaFilter contacts page, for example, needn't represent me via
hCard, but could instead point back to my MetaFilter profile with
rel="me", which could in turn point to the hCard on my personal
website with rel="me." As long as my personal website hCard is within
the XFNetwork (even though it may be multiple steps away), I shouldn't
need additional (likely redundant) hCards for myself.
Peace,
Scott
