Application scenarios for UML are clearly endless. I just discovered this old UML poems contest (similar to the UML Jokes contest in 2008, a summary here since it seems that the original site has now disappeared 🙁 ).
Some of the poems are linked here so take a look!. It shouldn’t come as a surprise that the “poem models” are very difficult to understand (and I would’nt say they follow a very normative UML syntax and semantics either), after all they are poems!. Interesting to see that the author of this UML-based interpretation of the Fire and Ice poem by Robert Frost is surprised to see that some people are actually able to read his/her diagram.
Remember that you can find more software/modeling humor articles in this page.
