Choosing a XML vocabulary today is a very challenging task quite similar to finding a web page before the development of the big web search engines and directories on which we rely today, the main difference being that it is much more dangerous to choose a "wrong" vocabulary than a "wrong" page!

If the bad news is that none of the tools which would help are available, the good news is that most if not all the information I need is available somewhere on the web and the purpose of this project is to propose a solution to retrieve and present this information.
