<KingsleyWebID#1> owl:sameAs <KingsleyWebID#2>

The semantics of the owl:sameAS predicate drive the inference drawn from 
the relationship. Basically, that <KingsleyWebID#1> and 
<KingsleyWebID#2> denote the same entity.


<KingsleyWebID#1> foaf:mbox <mailto:kidehen@openlinksw.com> .
<KingsleyWebID#2> foaf:mbox <mailto:kidehen@openlinksw.com> .

Since foaf:mbox predicate is an owl:inverseFunctionalProperty (IFP), I 
can infer (based IFP relationship semantics) that: <KingsleyWebID#1> and 
<KingsleyWebID#2> denote the same entity.

For additional clarity, subject, predicate, and objects in the 
statements above are all de-referencable URIs that resolve to data 
objects. The representation of a data object is a graph. And with 
hyperlinks in the mix (e.g., HTTP URIs) you have a Linked Data graph 
that scales to the World Wide Web.
