A Federated Approach for Array and Entity Environmental Linked Data
This paper discusses the main challenges that arise during the design and implementation of a federated solution for entity and array based environmental linked data. The proposed solution enables the integrated querying of geospatial relational databases, large scientific arrays of spatio-temporal dimensions and linked data sources with GeoSPARQL. To achieve this, a query decomposition algorithm and two new operators have to be incorporated in an already existing SPARQL query engine.
