The document discusses EMF Forms, a framework for building advanced editors on top of models. It provides an overview of key EMF Forms concepts like the editor, pages, master/detail blocks, and data binding. It also discusses related Eclipse modeling technologies like editing domains, undo/redo, and model validation. The document concludes with a demo of the Declarative Services tooling which uses these modeling components.
