In this project, an integrated hypertext and retrieval system for XML documents is being developed, suitable for a distributed, heterogeneous environment. The system will support a number of search and browsing strategies. It will allow for searching both in the metadata and in the fulltext. The system maintains a central database of metadata records and an index for retrieval and navigation, whereas fulltext documents are stored at their original location. In order to fill the database, a gathering component will access relevant sites in order to return new documents and/or metadata records. Documents are passed to the summarizer in order to generate metadata records automatically.
