  The development process of web information systems is often tedious, error
prone and usually involves redundant steps of work. Therefore, it is rather
e_x000E_fficient to employ a modeldriven approach for the systematic aspects
that comprise such a system. This involves models for the data structure that
shall be handled by the system (here: class diagrams), various editable and
read-only presentations (views) on combinations and extractions of the
underlying data (here: a special view language) and ways to connect these views
and define data flow between them (here: activity diagrams). In this paper, we
present the MontiWeb approach to model and generate these aspects in a modular
manner by incorperating the MontiCore framework. Therefor we shortly introduce
the infrastructure that helps to develop modular systems. This involves the
whole development process from defining the modeling languages to final code
generation as well as all steps in between. We present the text-based class and
activity diagram languages as well as a view language that are used to model
our system.
