| Definitionskos:definition | This OGC Testbed 11 Engineering Report provides a comprehensive review and comparison in terms of architecture, functionality, and usability of the OGC catalogue service standards CSW 2.0.2 and CSW 3.0. We are especially interested in how well the two standards provide support for open searches and federated distributed searches in current distributed computing paradigms. We also evaluated the support of semantic searches using different strategies, including (1) semantic mediation, a.k.a. ontology-based query expansion (Li et al. 2008; Li et al. 2011), (2) semantic association, which enables current catalogue information models to support semantic search (Li et al. 2014; Li et al. 2015), and (3) complete renovation of the CSW information model to be a triple store and utilize Semantic Web technology (Berner-Lee 2001) to support semantic query and data retrieval. Scenarios to search for hydrological data are developed to evaluate the performance of catalogue searching using the above strategies. Recommendations for adoption of CSW standards as well as tasks in advancing catalogue search and data discovery in future testbeds is also discussed. |
