ABSTRACT:
A network site often provides multiple offerings, each having their own context. The complete context for one of the offerings is stored. That complete context represents a root node in a hierarchical tree of context nodes, each node representing the context information for one or more of the offerings. Each node in the tree includes a reference to its parent node, and then a description of incremental changes to the context information as compared to the context information from the parent node. Accordingly, the context information for a particular node in the tree may be obtained by combining the complete context for the root node offering with incremental changes described in other nodes in the ancestral chain that leads from the particular offering to the root offering.
