URL-Encoding Methodology

##### General methodology:

Java type | JSON equivalent | UON
--- | --- | ---
Maps/beans | OBJECT | a1=(b1=x1, b2=x2) a1=(b1=(c1=x1, c2=x2))
Collections/arrays | ARRAY | a1=@(x1, x2) a1=@(@(x1, x2),@(x3, x4)) a1=@((b1=x1, b2=x2),(c1=x1, c2=x2))
Booleans | BOOLEAN | a1=true&a2=false
int/float/double/... | NUMBER | a1=123&a2=1.23e1
null | NULL | a1=null
String | STRING | a1=foobar a1='true' a1='null' a1='123' a1=' string with whitespace ' a1='string with ~'escaped~' quotes'

Refer to the UON specification for a complete set of syntax rules.
