Abstract: A method for processing and accessing data objects including a step (II) of gathering collected data objects (D) into groups of objects (DP1, DP2, DPM) associated with respective geographical areas (P1, P2, PM), a step (III) of classifying each object according to several categories of objects (DB1, DR1, DN1), a first step (IV) of classifying the objects into at least one of the object categories (DB1) according to an index common to all the object groups (DP1, DP2, DPM), and a second step (V) of classifying a part of the collected objects forming a particular group of objects (CR1, CR2, CRM) according to a second so-called hierarchical classification scheme (PH) common to all the object groups (DP1, DP2, DPM). The method further includes a step of navigating through selected geographical areas via either of the first and second classification schemes (PT, PH). The method is particularly useful for distributing and accessing documents on medical and pharmaceutical regulations.
