The article highlights the work carried out by the members of the URBE Interface Commission, supported by @Cult staff, to arrive at the creation of the Parsifal web. Starting with an analysis of the structural and ontological models that make up the Parsifal catalogue, organised within the framework of the Bibliographic Framework Initiative (BIBFRAME) project, it goes on to describe the choices made by the Commission to help users in their searches and, thanks to the results obtained, to familiarise them with entities and their relations, with linked data and with the Semantic Web. Finally, the concept of the authority file and the registration of the Authority cluster ID in Parsifal are analysed, albeit briefly.
