The document discusses the OpenAjax Alliance's efforts to promote interoperability between Ajax tools through the development of OpenAjax Metadata specifications. It describes how OpenAjax Metadata can be used to standardize documentation of Ajax library APIs and widget properties in a format readable by IDEs and other tools, addressing prior interoperability issues caused by each toolkit documenting in its own way. Examples of OpenAjax Metadata for JavaScript methods and widgets are provided to illustrate the standard elements and attributes.
