Semantic Web applications tests show that their usability is seriously
compromised. This motivates the exploration of alternative interaction paradigms,
different from the "traditional" Web or desktop applications ones. The
Rhizomer platform is based on the object-action interaction paradigm, which is
better suited for heterogeneous resource spaces such as those common in the
Semantic Web. Resources, described by means of RDF metadata, correspond to
the objects from the interaction point of view and Rhizomer provides browsing
mechanisms for them. Semantic web services, dynamically associated to these
objects, correspond to the actions. Rhizomer has been applied in the context of
a media house to build an audiovisual content management system. End-users
of this system, journalists and archivists, are able to navigate the content repository
through semantic metadata describing content pieces and the domain
knowledge these pieces are referring to. Those resources constitute the objects
to which, when the user selects one of them, semantic web services dynamically
associate specialized visualization and interaction views, the actions.
