OK, thanks. Just for the record, that isn't the way that the word is 
used in Semantic Web discussions.

That's sufficiently general and bland to apply to almost anything. 
But you don't mean semantics which supports a notion of inference 
which can be performed by a machine, right? And in any case, I 
wouldn't have said that text color was semantic even in this sense.

No, that's not what it means. See http://www.w3.org/2001/sw/. And 
that's not what 'semantic' means, either: 'more semantic' doesn't 
mean 'more precise'. Imprecise languages have semantics too.

I think not, most of the time, in fact: but certainly not in any 
sense of 'meaning' used in the context of talking about the SWeb.

Meaning to human readers, maybe. But that's not what the SWeb is 
about. Also, I wonder how many of these graphic devices are anything 
close to being 'standard', in fact. I bet most GUI designers would 
rather resent being told what colors to use in order to conform to a 
W3C directive. (BTW, 'requires an answer' is most often encoded by an 
asterisk, in my experience.)

Well, actually its a matter of public record: the term "semantic web" 
was introduced by the W3C, after all, and they have a reasonably 
clear meaning for it.

Interesting, but nothing at all to do with the SWeb project/goals. 
You are still talking about human/human communication here. The SWeb 
goal is to perform work without human intervention or communication 
being necessary. Perhaps 'inference web' would have been a better 
term, but we are stuck with 'semantic web' now.

How about calling your goal the 'semiotic web'? (Half serious 
suggestion: it might catch on and be useful. The world needs both 
semiotics and semantics.)

Thanks for the feedback, as it reveals a profound difference between 
usages of the S-word. We will all get very confused if we don't keep 
these differences in mind.
