Overview
It is essentially just a strongly typed dictionary (See COType.h for the mapping between possible COType values and the corresponding permissible Objective-C classes). Note that COItem only contains "value" obects (or possibly, sets/arrays of value objects). So, for example, references to other inner objects are stored as ETUUID instances. COItem acts as an intermediate layer during serialization or deserialization - the binary and JSON formats are both straightforward mappings of COItem to a byte stream.
COItem helps decouple object graph concerns (which are handled by COObjectGraphContext) from the details of actual serialization (handled by COItem(Binary) and COItem(JSON), and COItem also defines the abstract storage model (independent of a particular serialization format like binary or JSON) that CoreObject uses.
