Chris Waterson has authored a
primer
on XUL templates that describes the new rule based
extension syntax.
XUL,
Mozilla's XML User Interface Language, supports the
ability
to incorporate RDF graphs into its content model. This is
done using XUL
templates. Templates were recently enhanced
to support a more sophisticated rule based processing
model ala Prolog or OPS5. The new syntax allows the left
hand side of a rule
to match a specific RDF triple and supports the use of
variables.
