      <abstract>
        <p>The good old notion of frame, as introduced in the seventies, is a natural hub for cognitive sciences, knowledge representation, and natural language understanding. Developments in the last ten years, mainly due to the socio-technical ontology of the Web, have apparently changed the nature and scale of the notion, and pose new challenges. I will present a bird's eye view of the current situation, with a quick glance at human-robot interfaces.</p>
