XPath
Zur Extraktion beliebiger Teile eines wohl-geformten XML-Dokuments verabschiedete das W3C 1999 die Sprache XPath.
XLink
Das zugrundeliegende Problem, nämlich der Wunsch durch einen Link mehrere Ressourcen gebündelt referenzieren zu können, tritt in praktischen Anwendungen häufig auf. Beispielsweise beim Verweis auf mehrere Versionen eines Dokuments, alternativen Downloadservern oder Bildern verschiedener Auflösung.
Zu Realisierung erlaubt XLink die Bündelung von verschiedenen Verweisen zu einem einzigen erweiterten XLink. Nachfolgend ein Codeausschnitt, der dies für die Projektverwaltung zeigt.

The Need for Process
webengineering
Web Engineering – is the application of systematic, disciplined,and quantifiable approaches to the design, production,deployment, operation, maintenance and evolution of Webbasedsoftware products. [Gaedke, 2000]
Engineering is about the systematic application of scientific knowledgein creating and building cost-effective solutions to practical problems
