Navigating a collection of nodes by selecting a first node, generating a context list, and displaying the first node and list are discussed. Each context of a context collection includes a second node essentially referencing the first node. Another aspect includes a method of generating an address from a collection of contexts containing steps of receiving a selected attribute collection and generating the address. Another aspect includes a method of navigating a hypergraph including at least one context list containing at least one context including a node. The method includes steps of selecting a first context list of the context lists, selecting a first context of the first context list, and displaying the node of the first context of the first context list. Aspects also include computer programs implemented on computer readable media.
