Abstract

A computer environment includes an editor application enabling generation of a specification (e.g. a graphic description) defining attributes of a navigable semantic network. An example navigable semantic network as defined by the specification can include multiple resource nodes and corresponding links defining relationships amongst the resource nodes. In addition to defining nodes and relationships, the specification can define display rules, navigation rules, etc. associated with the navigable semantic network. The computer environment can further include a compiler, a view instantiation engine, and a presentation engine. The compiler compiles the specification into a semantic network model. The view instantiation engine instantiates different portions of a semantic network as defined by the semantic network model. The presentation engine initiates display of the instantiated portion of the semantic network. Based on navigation input, the view instantiation engine updates an instantiated portion of the semantic network for presentation by the presentation engine.
