This paper is dealing with a new web interface to display linguistic data on the web. This new web interface is a general proposal for the web. Its present name is Alexandria. Alexandria is an amazing tool that can be downloaded free of charge, under certain conditions. Although the initial idea was hatched six or seven years ago, its technical realization has only been feasible for the past two years. If you want to read the HTML page, for instance http://www.memodata.com, double click on any word at random and you'll see a window open with a definition of the word followed by a list of synonyms and expressions using the word. If not, your browser is not in French. Then, you have to use the menu to modify the target language and choice the French between 22 languages.
