Abstract. A methodology based on Semantic Web Initiative standards and technologies in order to improve rational use of urban, rural and semi-natural global cultural landscape resources in periurban fringe ex- pansion areas and in riconnection and ecological rebalancing green ar- eas, is proposed. This paper aims at showing how the need of advanced cooperative annotations and information exchange can be addressed us- ing a paradigm called “Interconnected Geo Semantic Web Communi- ties”. Furthermore we aim at designing the bases to implement a Deci- sion Support System to rationally manage resources which makes use of both geographical information advanced technologies such as remote sensing and Geographic Information Systems technique and semantic rules acting on ontologies. Based on the DBin platform a specific environment has been built to manage interoperable data arising from dedicated specific communities annotations and survey campaigns. The system features “collaborative annotations” and “intelligent” data structures which can be easily per- sonalized easily.

Introduction In order to adhere to the European Charter for the Sustainable Tourism, differ- ent stakeholders, belonging to thirteen municipalities of the “Comunità Montana delle Alpi Lepontine” (Cmal) in Northern Italy, cooperated using an advanced tool for Se- mantic Web communities, provided with geographical plug-ins which enable a real- time interaction with systems as Google Earth and Google Maps supported by spe- cific ontologies to edit, visualize and share information. 100 2nd Workshop COST Action C21 - Towntology
