No (Without (mis)using reification: see other recent messages on this 
list for discussion.)

That is the only mechanism available in RDF for doing so, and it has 
been explicitly suggested by several RDF sources. Without it there is 
no way to express anything in RDF other than a simple conjunction of 
ground triples.

We must be at cross purposes. I am talking about (the syntax of) 
logical constructs.

All objects? There are objects which have no name in any human 
language. Subatomic particules and almost all stars have no names and 
never will have. Even at a more mundane level, the world is full of 
entities which have no names. My toenail clippings, for example, were 
never christened.

Sorry if I am trolling (not sure what that means), but I am deadly 
serious.Talking about a 'system for giving all objects names' is so 
wonderfully, spectacularly, silly, that it strongly suggests that 
whoever says it does not know what they are saying. It is right up 
there at the Monty Python level. If I had any idea what it was that 
you were intending to say, I would assume that was what you meant: 
but I really do not know what you do mean.

No; NAMES allow people to give things names. Do you seriously think 
that people didn't give things names before the Web came along?

>and often provide ways to find out
>what they mean.

URL's provide a way to find out where some bytes are located. After 
that, as far as I can see we are all on our own. None of this 
provides a way to find out what anything MEANS, nor indeed could it 
possibly do so.
