This paper proposes a visualization scheme for large-scale collections of documents organized hierarchically. The scheme provides a concise and customizable view of OAI-PMH records. We assume that records are classified with a hierarchical algorithm or taxonomy. As a way of illustration, we chose the 1998 ACM Computing Classification System. A two-dimensional interface maps record attributes to visual elements: X- and Y-axes. Color, size, place and shape in the interface have a predefined intention. The scheme implementation is based of SVG charts. Users can explore data, metadata and to know the relationships between the records derived from the classification scheme. A collection of documents of the Universidad Politécnica de Puebla (UPPuebla) is used as a test bed for the proposed scheme. The paper reports preliminary results of out prototype version.
