In French society, many aids are proposed for each kind of population. In the particular case of disabled persons, it is quite difficult to deal with all the different information coming from heterogeneous contexts. Such different knowledge cannot be directly integrated, so we propose to build ontologies for each aspect. Then, we manage the cooperation of these distributed ontologies through a relational structure. Finally, to ensure the representation of the guid-ance interactive process, we model a workflow to follow through the successive steps of an individual file. This file will go with the disabled person, first with its own information, then with some administrative information and lastly with ser-vice propositions. The process is recursive allowing a better long-term assistance monitoring.
