UML Sequence Diagram headers

I love sequence diagrams to explain how a client/server request is handled. UML is natively pretty weak on client/server and even more on P2P.

Here is a notation which I’m not sure is official but helps a lot (see the “Sequence Diagram Header Elements” sub-section):

I’m currently using manual drawing to do that, just feels weird.

Hello Wernight,

Thanks for your message. Some of the notation in the link you provided are really non-standard in UML 2.x specification. But the major usage of modeling is for documentation and communication, so it is fine to draw it manually.

Best regards,
