Trying to support the presentation of large amounts of heterogeneous data on the World-Wide Web normally results in relocating and restructuring the original data. Our approach avoids these disadvantages by generating metadata imposing an arbitrary logical structure on existing and new data. This paper proposes a new high-level visual language as a userfriendly means to control the process of generating metadata, i.e., information repositories. The language has been designed to be useful even for unexperienced users. Its applicability is demonstrated by a real example, creating a repository of judicial opinions from publicly available raw data.
