+Extending JAXB - Representing Metadata as JSON
+==============================================
+
+This is the complete source code for the following blog post:
+
+* http://blog.bdoughan.com/2012/04/extending-jaxb-representing-metadata-as.html
+
+Summary
+-------
+
+In EclipseLink 2.4 the MOXY component includes support for representing the mapping metadata as JSON.  Now you can have a binding file like:
+
+    {
+       "package-name" : "blog.bindingfile",
+       "xml-schema" : {
+          "element-form-default" : "QUALIFIED",
+          "namespace" : "http://www.example.com/customer"
+       },
+       "java-types" : {
+          "java-type" : [ {
+             "name" : "Customer",
+             "xml-type" : {
+                "prop-order" : "firstName lastName address phoneNumbers"
+             },
+             "xml-root-element" : {},
+             "java-attributes" : {
+                "xml-element" : [ 
+                    {"java-attribute" : "firstName","name" : "first-name"}, 
+                    {"java-attribute" : "lastName", "name" : "last-name"}, 
+                    {"java-attribute" : "phoneNumbers","name" : "phone-number"}
+                ]
+             }
+          }, {
+             "name" : "PhoneNumber",
+             "java-attributes" : {
+                "xml-attribute" : [ 
+                    {"java-attribute" : "type"}
+                ],
+                "xml-value" : [ 
+                    {"java-attribute" : "number"}
+                ]
+             }
+          } ]
+       }
+    }
+
