Linking Information with Distributed Objects
Digital libraries can be viewed as managed and organized information spaces. In building and using these information spaces there is a need for technology to express, navigate and manage relationships. This paper presents the DL-LinkService, an object-oriented solution for structuring information in digital libraries where the relationships are implemented as distributed objects. The service is inspired by the CORBA Relationship Service, but our contribution is more flexible because the typing of relationships is independent of the implementation of the service. This paper describes the DL-LinkService and its possible use in three scenarios. A prototype is developed and our experience with the DL-LinkService is that this is a promising solution for expressing and navigating the structural information of digital libraries.
