You ask a reasonable question:

"Why can't the semantic web track 'whois' information of domain

but the answer must be:

because whois lookups are structured explicitly in a way to prevent
machine-readability because of the number of robots trying to harvest

If the "semantic web" were able to read that data, it would mean other
less well intentioned people and service could too, and would lead to an
inflation of challenge sentry systems protection whois from prying


Also could you qualify the statement: "there is in general a system of
ownership of URIs..." ? What is that system? Or are you claiming that it
is an implicit mix of DNS registration and site structure? A single
domain name can host n "content domain owners" as much as multiple
domain names can all refer to a single owner.

convincing element, as I know only *the* Microsoft can possibly own that
domain. (This will be a challenge for any SW search engine, because
no-one can own any URI, and so, seeing a URI alone means pretty much
nothing. That's one of the main differences between URL and URI, which
is usually swept under the rug.) 


I had to pick up in "no-one can own any URI".


First of all, terms:  URL is not really a term in the architecture of
the WWW.  I find it best to use "URI".  "URL" does occur in the browser
UI, but in the specs it has been used for various things, often a
derogatory term for a URI which might change. How are you using it here?
To mean the URI of a web page?

To mean an " http:"  URI?  If not, then why are you dealing with URIs
which are not HTTP URIs (tch, tch! :-)?  If so, then why don't you think
these HTTP URIs in the semantic web are owned? 


Why can't the semantic web track 'whois' information of domain
ownership, and maybe even SLL certificate information, of sites and be
aware of the social relationships, and use them intelligently? (perhaps
more safely than a human who will be confused by
http://www.microsoft.com.1000ripyouoff.crime/ ?) .  It is true that the
delegation of information within a site is not typically made explicit
(though it could be with site metadata).  But there is in general a
system of ownership of URIs, it seems to me, and it is important on the
SW in the social processes by which different groups get to define what
different terms mean.  So "no-one can own any URI" set off a red flag
for me.
