The emerging Model-Driven Engineering paradigm advocates the use of models as first-class citizens in the software development process, while artifacts such as documentation and source-code can be quickly produced from those models by using automated transformations. One of the many types of deployment platforms that can potentially benefit from such model-driven approaches are Content Management Systems, as these approaches can significantly accelerate the development of new web-applications and features, as well as simplify their maintenance. This work proposes the creation of a model-driven approach for the development of web-applications based on Content Management Systems. This approach is based on the creation of two modeling languages (which are situated at different f abstraction, and are used to both quickly model a web-application and provide a common ground for the creation of additional languages), and a mechanism for the processing of models specified using those languages...
