Sharing knowledge

We split the application apart into multiple sub-applications of the sub-domains, we do this to increase the size of the team and enable better cooperation between them.

The domain language is an important part of our design and we invested some time into building it throughout the development so far. We can draw on this and make this language available for other developers. The language, as we have seen it, slightly adjusts for each module and is a working document that needs to be kept up to date, and that means we need to find a way to keep it published.
