None of the above are supposed to indicate ownership. They indicate 
connotation.

If you want to indicate ownership, then you look to properties like:

1. made
2. maker or isMakerOf
3. creator or isCreatorOf.

Sticking with Dan's example below, I hope you can see the semantic 
fallibility (and implicit unsuitability)  of the relations above, in 
that context. For instance, the entity with the name attribute "Stephen 
Fry" didn't make (or create) any of those documents. Neither does the 
entity really own any of those documents, either.

Social network service providers are making documents that identify you 
(to their internal systems, primarily).

Microdata:


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