XArc (aka XLink--++)

[Gabe Beged-Dov]

I have written up a (very preliminary) specification for XArc. It can be
found at

           www.jfinity.com/xarc/spec-191214.

Here are the first few paragraphs of the introduction:

XArc is a simple specification for supporting atomic "linking" in XML. It is
the micro-kernel of capability that I think is needed in order to enable all
the more sophisticated modeling oriented linking scenarios that are
currently discussed under the rubric of "extended" links in the current
XLink specification.

One way to think about XArc is as a rewrite of the "simple" link construct
in XLink. This rewrite provides built-in capabilities on which to layer the
extended link facilities of XLink (albeit in a slightly more verbose but
unambiguous syntax).

The name XArc comes from the fact that "link" is woefully overloaded and the
definition of an arc in graph theory is the closest to what I see is needed
from the linking micro-kernel.
