International audienceThis paper deals with the processing of a formal electronic dictionary of French centered around the description of semantic derivations and collocations. The purpose of our project was to obtain a more flexible format for this dictionnary, the DiCo, which has a traditional structure. By compiling the DiCo, we get an object model which, in turn, can be stored in an SQL database. We show how the object model allows us to more easily access the data and gives us a new perspective on the structure of dictionary. This latter can be completly reorganized following new axes like lexical function links
