UML Resources

The web is a place where you can find almost everything, the problem is the ability to find what you are really looking for. If you type "UML" in a search engine you will find pages and pages that will meet this word. Here I have tried to list the most interesting links that in my experience I have found useful and I still use it every time I need.

This is the OMG website that standardized UML
This is the Rational website, where it is possible to find useful material: from specification, examples, and the leading software that use UML: Rational Rose. But I suggest to take a look at Rational RSA
This is one of the best link I have found dealing with UML: it contains useful links to papers, tutorials, presentation and much more
This is another useful links that deals a lot of information on UML: from software to developing tools
This last link that I put here compares different softwares that all implement UML as a modeling language
