Object-oriented modeling, querying, and indexing for multi-structured hypermedia document database

The hypermedia document is also a kind of structured document. However more factors should be considered in handling hypermedia documents because they contain multimedia data and also have multiple complex structures such as hyperlink networks and spatial/temporal layout structures as well as logical structures. We propose an object-oriented model for multi-structured hypermedia documents and multimedia data, and a query language for retrieving hypermedia document elements based on the content and multiple complex structures. By using an indexing scheme which exploits multiple structures, we can process queries efficiently with minimal storage overhead
