What you can model
Profile diagrams show how UML is extended: stereotypes, tagged values, and constraints for a domain such as persistence or messaging. They keep custom modeling rules consistent across teams.
How to use this maker
Name the metaclasses you extend, add stereotypes, document tagged values, preview the relationships, then export into modeling guidelines.
Notation that matters
Stereotypes extend metaclasses. Tagged values record properties of the stereotype. Constraints state rules the model must obey. Keep the profile small so toolchains stay practical.
Keep the diagram readable
Most product teams do not need a profile. Everyday class and sequence diagrams cover day-to-day design. Use a profile only when you maintain a shared custom modeling language.
