Additionally to this, it concerns the ability to take
into account the new evolution situations. The
originality of the presented approach is the fact that
it is based on the IS component concepts and IS
components recovering. These components have to
be expressed regarding to an efficient and unique
semantic for a group of actors within the
organization. In the other side, we introduced the use
of the cognitive space, applied in the case of an
institutional IS, which allows the expression of the
links between the "legal texts" and the IS. Finally,
the exploitation of such space allows the
identification invariants concepts that constitute the
core of the new IS.
