For example, the subject of a node may be determined by its situation as a role player in a single assertion, even though it is also a role player in many others. For another example, the subject may be collectively determined by multiple assertions, perhaps by virtue of playing a role type or set of role types in a set of assertions, or perhaps by playing a role in an assertion in which another roleplayer's subject is collectively determined.

Misplaced, this is still inventory of nodes.
