Analogous to the home model, sub-models can be created for further lines of business. These line-specific sub-models generally have no dependencies on each other, so they can be developed independently. To keep them cleanly separated in configuration management as well, a separate project is created for each sub-model. By splitting them into different projects, individual lines of business can be developed, versioned, and released independently of one another.

Furthermore, it has proven helpful not to manage the model and the product data in a single Eclipse project, but in two separate projects. In this way, a business department can define the product data independently of application development.

Overall, this results in the following example project structure:
