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.

En aquest cas, alguns dels col·lectius de la lluita contra aquests cultius demanen que la Universitat de Lleida rebi una especialització en Agricultura Ecològica . Asseguren que serien uns estudis pioners que servirien al centre per recuperar prestigi.
