In a matching system one or more related techniques use correlators to match entities and to look up metadata. Correlators are names that enable the matching system to associate entities with other entities. Attributes comprised of name/value pairs are used by the matching system to determine if two entities match. When two entities match, a process associated with an entity may be executed using the data associated with one or both of the matching entities. If the matching system is unable to determine a best match, all matching entities are provided to another process or human for further review. The matching system provides for the injection of new entities or correlators, to dynamically change the behavior of the system. Entities can be defined using a hierarchy, so that some of the entity properties are defined through an inheritance relationship with parent entities.
