JavaScript Persistent Object Notation (JPON)

JavaScript Persistent Object Notation (JSPON) is a data-interchange format with the goal of simply being a defined usage of JavaScript Object Notation (JSON, see www.json.org) to facilitate JavaScript objects that are intended to persist by defining a scheme to provide the necessary semantics needed for efficient and meaningful persistent objects. JSPON is pure JSON and maintains the same simplicity of JSON, and establishes a format for serializing and referring to objects to enable the persistence of JavaScript objects and object graphs by defining a set of fields for identification, deferred value loading, decentralized object creation, and primitive value, function and array object augmentation.

JSON provides simple straightforward mechanism for serialization of objects that can efficiently and easily be read by humans and machines. JSON can be adequate for the persistence of simple small objects. However applications that have large complex object graphs and sets of data generally require the exchange of smaller subsets of the data/object graph to be transferred and persisted at a time rather than requiring an entire object graph to be treated as whole, as well as allow objects to be referred from multiple fiels. Such operations on subsets of data entail identifying objects within a graph and allowing for transfers of subsections of object graphs (and not just end point subsets). JSPON provides the common language so that objects can be passed with proper identification and reference information. This also allows objects to be referred to more than once (not possible within a normal JSON object graph). Standard JSPON simply defines several fields that can be added to JSON object to assist in data description.
