Further, we implement a suite of tools for automatically transforming \INSPIRE\ data and metadata into \RDF\ triples with geometries. The compiled geographic and thematic information can then be loaded into semantic repositories for querying or interlinked with other data. Our open-source solutions essentially repurpose existing \INSPIRE\ SDIs, so as to promote uptake and facilitate their reuse in practice. Finally, as a case study, we report our experience in validating this approach on a real-world \SDI\ with publicly available data for Greece in order to expose its contents through (Geo)SPARQL endpoints.
