Ask HN: Is anyone using UML in their work?

2 points by khaled_ismaeel ↗ HN
I'm very curious to know about the real-life applicability of UML.

All examples I have seen so far are the shape-rectangle-circle kind of examples. Besides, I have been browsing around open source projects a lot recently and none of them had a design document or similar.

Sequence diagrams, in particular, yes.

I do these with PlantUML in Gitlab Issues (which has in-built support for PlantUML)

Can you provide some links?

If you google `PlantUML Gitlab` you should find some blog posts and docs, but if you are don't fancy reading this, try pasting this into a Gitlab Issue body

   ```plantuml
   Alice -> Bob: Authentication Request
   Bob --> Alice: Authentication Response
   
   Alice -> Bob: Another authentication Request
   Alice <-- Bob: Another authentication Response
   ```
I believe Github has similar support also.

See this for a whole lot more about PlantUML: https://plantuml.com/sequence-diagram

I meant links to instances where you used UML diagrams in an active issue. I'm more interested in seeing how people use it rather than how to make it.

Sorry, it's a private gitlab instance.
