The recently published CURIEs WD [1] refers to the 'ifragment'
production in the IRI grammar [2]. This production rules out several
of the examples given:
home:#start
#start
?foo=bar&other=other#fragment
because '#' is not allowed in ifragment.
Working through the grammar from the IRI RFC, the following are the
characters which _are_ allowed in an ifragment:
!
$
&
'
(
)
*
+
,
- -
.
/
:
;
=
?
@
_
~
ALPHA
DIGIT
ucschar
pct-encoded
As I suggested in my previous comment, it seems to me that the
'irelative-ref' production is much more likely to be the one you want.
However note that ':' is allowed as part of both ifragment and
irelative-ref -- it follows that many strings of the form '...:...'
are ambiguous as CURIEs -- are they unprefixed, or prefixed?
Presumably you wish them to be interpreted as prefixed -- if so, you
need to say so.
