Dan's example in HTML+Microdata (which by notation choice 
*inadvertently* blurs visibility of the relation semantics in play) :

<div itemscope itemtype="http://schema.org/Person">
<span itemprop="name">Stephen Fry</span>
     (<a itemprop="url" 
href="http://www.stephenfry.com/">stephenfry.com</a>,
      <a itemprop="sameAs" 
href="http://twitter.com/stephenfry">twitter</a>,
<a itemprop="sameAs"
href="http://en.wikipedia.org/wiki/Stephen_Fry">wikipedia</a>)
</div>


Turtle  translation:

<> <http://www.w3.org/ns/md#item> [
<http://www.w3.org/1999/02/22-rdf-syntax-ns#type> 
<http://schema.org/Person>;
<http://schema.org/name> "Stephen Fry";
<http://schema.org/sameAs> <http://twitter.com/stephenfry>,
<http://en.wikipedia.org/wiki/Stephen_Fry>;
<http://schema.org/url> <http://www.stephenfry.com/>
      ];
<http://www.w3.org/ns/rdfa#usesVocabulary> <http://schema.org/> .


What does Dan's example demonstrate?

The function of a *pronoun* in a sentence or statement. Basically, the 
example makes the following claim, using terms from <http://schema.org/> 
(a Vocabulary):

Someone or something has determined the existence of an entity that has 
the following discernible attributes:
Name: "Stephen Fry"
Type: Person
referencedBy: <http://twitter.com/stephenfry>, 
<http://twitter.com/stephenfry>, <http://www.stephenfry.com/> .

Personally, I wouldn't denote a relationship predicate/property for this 
relation, in this manner, due to the *equivalence* intuition. 
Alternatives inclued:

1. referencedBy
2. subjectOf
3. identifiedBy -- this is my personal favorite .
