Concept hierarchies greatly help in the organization and reuse of information. Multidimensional, hierarchy-organized data are widely used in a variety of applications, such as data warehousing, mining network data, etc. In the HiPPIS (Hierarchical Peer-to-Peer Indexing System) project, we investigate methods for efficiently storing and querying multidimensional data organized into concept hierarchies and dispersed over a network.
