Right now, SPARQL uses less-than and greater-than
brackets to identify a URI. This is probably due to
the influence of N3 and Jena's RDQL. So they are
shown as:
<http://example.com/uri>
However, this is hard to write in XML, since every
less-than sign should be escaped. Therefore, I think
SPARQL should use Clark Notation [1] to represent
them. That is:
{http://example.com/uri}
or even:
{http://example.com/}uri
I don't know whether the second form should be allowed
or not.
Now I am aware that the WG wants to use curly-brackets
where it currently uses parentheses [2]. However
there doesn't seem to be a particular reason given for
the change. Why change what already works?
