What is "webml"

WebML (Web Modeling Language) is a visual notation and a methodology for designing complex data-intensive Web applications. It provides graphical, yet formal, specifications, embodied in a complete design process, which can be assisted by visual design tools.

In 2013 WebML has been extended to cover a wider spectrum of front-end interfaces, thus resulting in the Interaction Flow Modeling Language ( IFML), adopted as a standard by the Object Management Group (OMG).

This method has five models: structure, derivation, composition, navigation and presentation. These models are developed in an iterative process.
