[EN] A rule-based topology software system providing a highly flexible and fast procedure to enforce integrity in spatial relationships among datasets is presented. This improved topology rule system is built over the spatial extension Jaspa. Both projects are open source, freely available software developed by the corresponding author of this paper. Currently, there is no spatial DBMS that implements a rule-based topology engine (considering that the topology rules are designed and performed in the spatial backend). If the topology rules are applied in the frontend (as in many GIS desktop programs), ArcGIS is the most advanced solution. The system presented in this paper has several major advantages over the ArcGIS approach: it can be extended with new topology rules, it has a much wider set of rules, and it can mix feature attributes with topology rules as filters. In addition, the topology rule system can work with various DBMSs, including PostgreSQL, H2 or Oracle, and the logic is performed in the spatial backend. The proposed topology system allows users to check the complex spatial relationships among features (from one or several spatial layers) that require some complex cartographic datasets, such as the data specifications proposed by INSPIRE in Europe and the Land Administration Domain Model (LADM) for Cadastral data ; This work has been partially supported by the research project "Creation and cartographic feeding of spatial data Infrastructures in the local government by means of a data model that integrates cadastre, planning and cultural heritage", CSO2008-04808 from the Spanish Government (CICYT) and the European Union Funds. ; Martínez Llario, JC.; Coll-Aliaga, E.; Nuñez-Andres, M.; Femenia-Ribera, C.

International audience ; The XIth region (Aysen del General Carlos Ibañez del Campo) is in Chile a space in a relative geographical isolation : the traditional communications (roads, airports) are little developed and in structuralization. The modern communication tools (telephone, internet) are still in the embryonic state. In this context, the isolation is lived as a major constraint the effects of which affect all the fields of the economic, social and environmental reality. The current population is concentrated essentially in some urban poles which gather 80% of the population. The remaining 20% live in even more remote areas, mountain valleys and islands. The isolation in these sites is even more obvious. The inhabitants develop, there, activities connected essentially to fishing and to extensive breeding. At stakes for these populations are the vital questions of the preservation of their activities and the recognition of their specificities, which certainly depend on a regional recognition and new means of communications.The subject of this research is to study the question of the isolation in the most geographically remote sectors (fjords, islands and mountain valleys) through the analysis of the perception of these remote population and public and political actors in Aysen. The study analyzes the assets and constraints associated with remoteness, and concludes on the stakes and perspectives of these peripheral areas and their population. ; Au Chili, la XIème région (Aysen del General Carlos Ibañez del Campo) est un espace relativement isolé géographiquement.
