Towards Semantic Spatial Data Infrastructures : A framework for sustainable development

Next generations of SDI should be oriented to semantics in order to deal with user’s languages and requirements in a maximum level possible. Based on a new vision called “The Semantic Web”, inspired in the past decade by Tim Berners-Lee, inventor of the Web and current director of the World Wide Web Consortium (W3C), this paper defines Semantic Spatial Data Infrastructures (SSDI) by describing their main components and principles. SSDI services should be equipped to enable a machine to understand human language, but to reach this state, it is necessary to create not only suitable semantic services, but also user domains ontology into a general semantic oriented SDI framework. This paper demonstrates that in the user-driven SDI, beyond the need for a service-oriented infrastructure, there is a need to describe user context/domains (domain ontologies) and to translate them into logical ones, in order to match appropriately with the required services. This paper presents a Semantic SDI Framework for sustainable development as part of an ongoing research into the CYTED-project “Evaluating and strengthening Spatial Data Infrastructures for sustainable development in Latin-America and the Caribbean” (IDEDES-606PI0294). The Semantic SDI framework for sustainable development includes social, economic and environmental dimensions expressed by means of domain ontologies and conceptual maps. The DF-P-S-I-R framework, used in the Global Environmental Outlook (GEO) by UNEP, the ecosystem approach and other international sustainable development reference models were premises to conceptualize the SSDI framework for sustainable development. Finally, some more detailed ontological components of an environmental dimension are shown, as well as, a semantic services perspective proposal, necessary in a Semantic Spatial Data Infrastructure.
