PowerBookmarks: an advanced Web bookmark database system and its information sharing and management

Bookmarks in existing Internet browsers only provide limited functionalities: storing URLs, titles, and organizing folders for manual categorization of URLs. We extend the notion of bookmarks by introducing the concepts and functionalities of databases, such as query, re-organization, information sharing, view, and access control. We have developed an advanced Web bookmark system, PowerBookmarks, which allows users to select URLs of their interests to construct their bookmark databases for subsequent querying. PowerBookmarks supports organization of bookmark URLs as an hierarchical structure. Users can also set the access control for sharing their bookmark databases with other users.
