Although the Web has grown continuously since its introduction
in the early 90's, its technical foundations have remained
relatively stable. However, the introduction of XML, along with a
sequence of related technologies such as XPath, XLink, and
XPointer, has heralded a substantial change in the way in which
content can be managed. The most significant of these changes is
with respect to the hypermedia functionality which is enabled by
the new technologies of XLink and XPointer, especially richer
linking and navigation models. This book will describe the new
hypermedia features of the XLink/XPointer-enabled Web for
developers who are interested in how these new concepts can be used
for Web publishing. This book will offer its readers an overview of
hypertext and hypermedia possibilities as well as the possibilities
of the particular hypertext technologies that are currently being
developed for the Web.
