XML Linking Language (XLink) Version 1.0 allows elements to be
inserted into Extensible Markup Language (XML) documents to create
and describe links between resources. The XML syntax creates
structures that can not only describe links similar to the simple
unidirectional hyperlinks of today's HTML, but go well beyond.
Along with providing linking data structures, XLink additionally
provides a minimal link behavior model. Therefore, higher level
applications layered on XLink will often specify alternate or more
sophisticated rendering and processing treatments.
XLink provides a framework for creating both basic
unidirectional links and more complex linking structures, according
to the WC3. It allows XML documents to assert linking relationships
among more than two resources, associate metadata with a links and
express links that reside in a location separate from the linked
"This is a useful and important time in the development of the
XML family of technologies," said Janet Daly, WC3 spokesperson. "It

The XML Linking Working Group released the
recommendation this week. It is available for public review
until October 3.
"The Working Group is asking developers to look at the document,
experiment and give us feedback," Daly said. "We are also hoping to
see open source implementation, which is important for the success
of a specification."
