1. Method for controlling access rights to information objects in a semantic network stored in a digital storage medium, which consists of nodes and edges, whereby the nodes represent information objects and the edges represent semantic relations, wherein a) users or user groups are stored as nodes in said semantic network, wherein b) users or user groups can be set in relationship with other information objects, c) access rights are configured and stored in the form of a searchable set of access rules, d) requests to the access right system are described by the requesting user (u), the semantic object the user requests to access (t), and the operation (op) the user requests to perform on t e) access permissions are computed dynamically on demand.
