>> OGNL started out as a way to set up associations between UI components

>> Today OGNL is maintained by Lukasz Lenart.

>> Background
>> OGNL is a long living project born in the 1997 thanks to Drew Davidson

>> Rationale
>> OGNL stands for Object Graph Navigation Language. It is an expression

>> Many people have asked exactly what OGNL is good for. Several of the

>>
>> * A binding language between GUI elements (textfield, combobox, etc.)
>> to model objects. Transformations are made easier by OGNL's
>> TypeConverter mechanism to convert values from one type to another
>> (String to numeric types, for example).
>> * A data source language to map between table columns and a Swing TableModel.
>> * A binding language between web components and the underlying model
>> objects (WebOGNL, Tapestry, WebWork, WebObjects).
>> * A more expressive replacement for the property-getting language
>> used by the Apache Commons BeanUtils package or JSTL's EL (which only
>> allow simple property navigation and rudimentary indexed properties).
