This site is devoted to the development of the concept of intelligent Metadata Management, particularly in the library environment. The main thrust of this work is developing management systems to support the aggregation of non-heterogeneous record-oriented, item-level metadata from diverse collections via OAI; normalizing it, augmenting it, and generally improving the quality; then re-serving the resulting resource-oriented, item-level, aggregated metadata from a central metadata repository for use in building resource-discovery services.
