You are avoiding the question.

What URI (not RDF "query") denotes "Dan"?

The example given suggested that the URL of Dan's photo denoted "Dan"
and I argued that it didn't, and you are now avoiding my response
by offering yet another way to denote "Dan".

I'm quite aware of the power of RDF to define complex queries
(templates of statements) which may (or may not) denote "something".

The value of a URI is that it *always* denotes *one* thing. There
may be other means, or even other URIs to denote that same thing,
but for any given URI, it denotes only one thing. That's why it's
useful to e.g RDF and similar tools as a universal unique identifier.
