Aufbau einer verteilten digitalen Bibliothek für nichttextuelle Dokumente - Ansatz und Erfahrungen des PROBADO Projekts

The PROBADO project is a collaborative research effort aiming at prototypical development and operation of a distributed digital library system for heterogeneous, nontextual documents. The project considers all steps of the processing chain in libraries ranging from repository compilation, semi-automatic, content-based indexing, to visual-interactive search and presentation, and operational aspects. In this paper, we describe the chosen approach, specifically detailing on experiences and lessons learned up to now in the course of this project.
