The paper deals with the possibility of creating a topic map based system where different sectors of cultural heritage would interact with users, by monitoring the navigation histories of users and the statistics on the searches, in order to authorize variant form of names. The problem of managing different sectors and harmonizing them both from a structural and a semantic view point, by using topic maps, is also discussed. With regards to this, we are introducing two projects, which are largely based on the above mention use of topic maps.
