Justin,

I assumed "account" and my suggested "hasAccount" denoted actual 
"account ownership" oriented relations i.e., relationship properties 
that determine how two entities are associated. In short, my entry into 
this thread was all to do with providing counter points to some 
arguments about unambiguous vs ambiguous entity denotation, using HTTP 
URIs.

Of course I wouldn't be suggesting "account" or "hasAccount" as 
identifiers for coreference relations.

'same as', 'sameAs', :sameAs, <http://www.w3.org/2002/07/owl#sameAs>, 
are different kinds of identifiers that denote age-old coreference 
relations. The only issue is whether inference and reasoning on these 
relations is scoped to:

1. humans
2. machines
3. both.

Hope this clarifies my position :-)
