Object Identity As A Query Language Primitive

Summary: Object identities (oids) serve as a query-language primitive for a general object-based data model that permits sharing and cycles. IQL leverages oids to represent structures, manipulate sets, and express any computable query; it is statically type-checked, bottom-up evaluable, and extendable to inheritance, with a parallel value-based infinite-tree model.
