Declarative User Interfaces
DNAOS offer integrated declarative XML-based development environment where complex forms, wizards and workflows can be declared simply and where the environments can easily be expanded. Environments also provide web based interfaces to manage operations and build portal pages and portlets.

When developing for DNAOS, there is no need for JSPs, taglibs, Struts, Cocoon, or XForms, but they are all supported by DNAOS where they can be used as usual. Declarative XML is all that is really required as DNAOS offer an integrated set of services, including workflow with session history and automation, as well as advanced validation, security, and pipeline configuration.
