I've recently started studying the Unified Modeling Language.
I'm currently using an exam book as a study guide, because it presents features without holding back on information-representation at all. Afterward, I will study the book made by the first 3 who started developing UML (since OOPSLA/OOSE I believe, though I could be off by a few years >_<).
But, as I started learning the features in the UML, I realized that UML itself is a language O_O
Some of you may laugh at this, but I didn't at first think of UML as its own language. I thought that UML was a model with specific features for describing things, though this example is probably still not a convincing defense.
I realized that it has such a defined set a features for organizing information (not just data, but practical things too) that it is probably the most portable concept across different languages and design-ideas.
This makes me curious, though. If this language is so versatile and variable, why is there no forum dedicated to design-ideas and refinement of UML? Is the UML too easy to be placed in a forum (because, to me it "looks" easy, but understanding the fundamentals of UML and improving organization skills and data-representation isn't quite as easy)? Is it too broad?
