- linking and addressing

Overview:

XLink, XPointer, and XPath - three layers of languages

XLink:

Problems with HTML links - why do we need something new?
The XLink linking model - a generalization of HTML links
An example - a link between two remote resources
Linking elements - defining links
Behavior - show and actuate
Simple vs. Extended links - compatibility issues
HLink vs. XLink - a new alternative?

XPointer, Part I - using XPointer in XLink:

XPointer: Why, what, and how? - introduction
XPointer vs. XPath - what is the difference
XPointer fragment identifiers - the structure of an XPointer

XPath:

Location paths - the central construct
Location steps - expressing node-sets
- Axes - selecting candidates
- Node tests - initial filtration
- Predicates - fine-grained filtration
Expressions - a little expression language
Core function library - the built-in functions
Abbreviations - convenient notation
XPath visualization - a useful tool
XPath examples - continuing the recipe example
XPath 2.0 - the next version
