The article starts with a definition of what localisation is and where it stands in respect to internationalisation, globalisation, and translation before analysing the nature and sequence of tasks and instruments involved in the localiser's standard activities--cloning or pseudo-cloning a Web site, localising software packages or video games and their accompanying documentation. Once the contents of the services performed by the localiser have been ascertained, a profile emerges for that particular species of translators: that of the 'ultimate translator' in terms of domain specialisation, writing and rewriting skills, control of ergonomics, quality management abilities, project management skills, project team management know-how, and naturally enough, mastery of anything that has to do with computer science, computer technologies and computer-assisted whatnots. The author thinks that translator profiles should be upgraded in such a way that all translators become able to grab chunks of the new localisation markets. His choice would be to give the new translators all of the skills and competencies required of some kind of 'engineer (ingenieur) in multilingual and multimedia communication', whose abilities and markets would include all forms of what, under the name of localisation, is but a thrice specialised and better paid variant of translation. The emergence of localisation as a collection of new markets, a set of not so new skills, and a new frontier is the time for translators to decide where they stand and how much they are prepared to change, and for training institutions to adapt to the new challenges. That means that institutions must teach localisations as a matter of course but also reposition themselves more radically as schools of multilingual, multimedia engineering so that their trainees may keep abreast of changes that are already reshaping demand by work providers.
