WEBGIS and BLOG allow to promote a spread of spatial data knowledge, to consult planning documents in the Internet, increasing transparency level of programming choices and involving different stakeholders participation. The ontology is intended as an in progress powerful tool, increasing knowledge rationality. Ontologies can help the community by defining and explicating a shared language and strengthening the efficacy of direct interactions.
