Authenticity is not an absolute and constant quality inherent in an object or an experience; it is constructed in the process of research. Actors inscribe and attribute it to both material objects and subjective processes like communication and consumption. This article from the research group seeks on the one hand to reflect on the historical scope of action and action patterns among actors from various disciplines between the conflicting priorities of authentication and communication, and on the other to find ways to visualize and operationalize attribution processes through joint reflection. When we look at both history and the discussions fifty years after the Venice Charter, its idea to hand on historic monuments “in the full richness of their authenticity” has turned into an abundance of vibrant action and decision- making.
