Re: ISSUE-103: substantive issue that requires opinion + discussion

The issue is to use something like cu:prefix:suffix instead of 
[prefix:suffix] for safe CURIE-s.

The argument being

"the [...] syntax effectively introduces a new kind of URI - it extends 
the URI space"

I am not a big fan of the [...] syntax either, I must admit, but I 
consider it as a, well, necessary evil. So the proposal has some merit, 
that is for sure.

But... the problem is that, in my view, CURIE-s do _not_ introduce a new 
kind of URI. From hindsight, calling them CURIE-s (Compact URI) may have 
been a mistake because it suggests that. CURIE-s are some kind of macros 
and not URI-s. (Maybe we should call them URI Macros (URIM), but that is 
too late.) The syntax proposed by Jonathan sort of reinforces the 
(mistaken) view that these _are_ special URI-s. By the way, Jonathan 
says (as a pro argument):

"it would eliminate the need for a new URIor[safe]CURIE datatype since 
you could just use URI"

Which, in view of what I said, is not really true or maybe misleading.

Note that Jonathan also raises some points whose validity I cannot 
really judge at the moment. Is there really a possibility to use a 
relative URI spelled [...], for example? Or a future expansion of the 
URI space that include [...]? I have no example right now for the 
former, but we indeed cannot exclude the danger of the latter. That one 
is, for me, the most compelling argument of his proposal.
