jQuery plugin for parsing metadata from elements

Sets the type of metadata to use. Metadata is encoded in JSON, and each property in the JSON will become a property of the element itself.

There are three supported types of metadata storage:

  attr:  Inside an attribute. The name parameter indicates *which* attribute.

  class: Inside the class attribute, wrapped in curly braces: { }

  elem:  Inside a child element (e.g. a script tag). The name parameter
         indicates *which* element.

The metadata for an element is loaded the first time the element is accessed via jQuery.

As a result, you can define the metadata type, use $(expr) to load the metadata into the elements matched by expr, then redefine the metadata type and run another $(expr) for other elements.
