Abstract:

While exploring the options for traversing JSON, I discovered that there is no official W3C documentation, or even a draft. As a subset of the ECMAScript language specification, it will probably remain under the governance of ECMA International. So unlike XPath, which is a commonly accepted language for traversing XML, JSON must rely on JavaScript’s object notation.
