Abstract
Different strategies can be adopted in order to enable new ways of searching geospatial resources, leveraging the Semantic Web and Web 2.0 technologies. The authors propose a Discovery Augmentation Methodology which is essentially driven by the idea of enriching the searchable information that is associated with geospatial resources. They describe and discuss three different high-level approaches for discovery augmentation: Provider-based, User-based, and Third-party based. From the analysis of these approaches, the authors suggest that, due to their flexibility and extensibility, the user-based and the third-party based approaches result more appropriate for heterogeneous and changing environments such as the SDI one. For the user-based approach, they describe a conceptual architecture and the main components centered on the integration of user-generated content in SDIs. For the third-party approach, the authors describe an architecture enabling semantics-based searches in SDIs.
