abstract = {Current hypermedia modeling techniques such as OOHDM, RMM
or WebML rely on class-based domain models to guide the hyper-
media construction process. In this paper we discuss the notion
of role-oriented models as particularly suited for capturing differ-
ent semantic contexts of hypermedia interfaces. The key idea is
to allow resources to fill different roles which specify how these
resources can be embedded in different link structures. After an
overview of some class-oriented models, we discuss in detail the
main features and benefits of role-oriented modeling compared to
conventional class-oriented approaches, and make clear the distinc-
tion between attributes and links associated with objects via their
natural types and attributes and relationships for an object specified
by the different roles the object can fill. Two detailed examples, one
discussing the use of role-oriented models for the specification of
link structures in learning materials, another one for the specifica-
tion of contexts for a tourist information system, show how these
role-oriented models can be applied in different areas. Finally we
show how such models can be easily expressed and implemented
using the W3C standard for web annotation, RDFS, and show that
a role-oriented semantics is actually closer to the intended use of
RDFS schemas than the ''default'' class-oriented semantics.
