Abstract :
Discusses how to use an object-oriented (OO) query language for designing some features of hypermedia applications. We show that it allows designers to define navigational contexts by retrieving instances related by special relationships (one-to-many or aggregation relationships) specified in the conceptual model or as a set of a arbitrary instances where a condition holds. We first describe an OO hypermedia design model, supporting nodes, links and their anchors and perspectives. We then present the query language and give some examples showing our strategy to define navigational contexts.
