1) The document discusses Domain Specific Modeling Languages (DSMLs) and their use for enterprises. DSMLs are modeling languages tailored for specific domains that offer gains in expressiveness and ease of use compared to general modeling languages. 2) Metadone is introduced as a tool for creating DSMLs through a graphical modeling environment without programming. It allows customizing existing modeling languages or creating new ones for specific domains. 3) Examples of potential DSMLs are given for various domains like logistics, heating systems, automotive entertainment systems, medical devices, and IoT systems to demonstrate how DSMLs can be customized for different application areas of enterprises.
