RE: More on distinguishing information resources from other resources

well, see, I *do* know lots of things about the British Broadcasting
Corporation. I just don't know what *URI* to use to identify that
particular resource. I might reasonably choose http://www.bbc.co.uk, and
assert the following:

<chris sizemore> is employed by <http://www.bbc.co.uk>

but, then later, when the owner asserts the following:

<http://www.bbc.co.uk> is a resource of type <"portal homepage"> (crude
example, but I hope the point is valid)

the owner's assertion has rendered mine false, which I agree is
absolutely her/his prerogative. 

again, my question is not really about the effects of the compromise on
http-range-14; it is more about the knock-on effects of "a URI
identifies what the owner of that URI intends it to identify."

again, the difficulty I'm having conceptually is: how do *non-owners* of
a URI know, unambiguously, what resource a URI identifies? this URI:
http://www.flickr.com/photos/38333831@N00/22537567/ probably identifies
a particular photograph, but the owner might intend for it to identify
the Moon. and it'll be even more  difficult to learn/second-guess the
intentions of the URI owner with URIs that don't offer a representation
of some kind, because then there are very few clues.

and it sounds like a non-owner like myself CANNOT know, at least until
the owner starts publishing some assertions, which MIGHT begin to
disambiguate things a bit. if this is the case, then fair enough.

I'm probably not seeing the big picture clearly enough, but I'm
expecting this to be a difficult area for me over the next few years:

1) can *non-owners* of a URI *ever* know, with certainty, exactly what
resource a URI identifies? if not, then doesn't everyone have to
publish/own custom URIs for every concept about which they need to make
assertions?
2) if I want to make assertions about a resource that I don't "own"
("love", for instance), what URI should I use to minimize mapping to
other URIs which also identify the resource? I'm confused about how
consensus around a URI is meant to develop.

I am curious, how can you assert something that you don't know.  Also, I
think the motto of SW is "everyone can say anything about everything".
Your
assertions are always going to be your viewpoint on that URI and won't
reflect the viewpoint URI's owner anyway.  Once again, "it doesn't
matter".

But I am just an observer, not a member, of the TAG.  So, take my
opinion
with a grain of salt. :-)
