1. A system for determining context comprising: a processor; and one or more computer-readable media encoded with: a first hierarchical tree structure having multiple nodes associated with a first context, wherein the first hierarchical tree structure resides on the one or more computer-readable storage media and the first hierarchical tree structure comprises a standardized view of the Earth and a plurality of attributes, one of which comprising information that pertains to the tree with which the node is associated; a second hierarchical tree structure having multiple nodes associated with a second context, wherein the second hierarchical tree structure resides on the one or more computer-readable storage media and the at least one second hierarchical tree structure comprises a plurality of attributes, one of which comprising information that pertains to the tree with which the node is associated and an organization-specific view of a portion of the Earth, the organization-specific view comprising a physical/logical entity that links into specific portions of the Earth and the organization-specific view has no context outside of the organization, wherein the second hierarchical tree structures comprise a plurality of nodes, wherein each node is assigned an organization-specific proprietary identifier; and one node from the second hierarchical tree structure being linked with one node on the first hierarchical tree structure by a link that is configured to enable a complete context to be derived from the first and second contexts, individual nodes having unique IDs that serve as a basis by which attributes are assigned to goods or services, wherein attributes assigned to goods or services comprise a relative importance that identifies geographic importance relative to a region; said multiple nodes comprising parent and children nodes, wherein some of the parent nodes and their associated children nodes having IDs that are unique for the associated node.
