There are certain things which need to be sorted out with respect to Ajax and one of them is with respect to interoperability issues. The OpenAjax Alliance is now working towards dealing with interoperability issues related to Ajax development environments along with creation of secure mashups.

The OpenAjax Alliance has worked towards creation of draft for increasing interoperability of Ajax and securing mashup creation apart from making widgets interoperable for use in mashups.

The problem lies with respect to AJAX tool kit documenting widgets and APIs in its own manner and the group plans to take care of these problems with new set of specifications dubbed as OpenAjax Metadata for AJAX Libraries which makes possible delivery of industry standard XML for JavaScript APIs and user interface controls. So you will see a visual design with the help of widgets from Ajax libraries and intelligent code assist for APIs across diverse AJAX libraries.
