The document discusses the Eclipse Rich Ajax Platform (RAP) and its development as part of the Eclipse ecosystem, outlining its capabilities and limitations in comparison to Rich Client Platform (RCP) applications. It highlights features such as compatibility with RCP APIs, the ability to migrate existing applications, and the deployment of RAP as OSGi bundles. Additionally, the document addresses the challenges faced when adapting RCP to web applications and presents resources for further information and learning about RAP.
