Websites become more often based on data warehouse architectures. Our group uses the website modeling language SiteLang [TD01]. This language has reached a maturity that allows simple application and goes far beyond what other approaches can handle: It is powerful, consistent, has a well-developed theory fundament [Tha00a,Tha00b], does not allow to create confusing specifications, uses a powerful methodology [ST00,Tha03] applied in three dozen projects, and has a playout and layout specification supporting database-backed generation of websites.
