1.4 Future work
Future work in envisioned as follows:
1.4.1 Ontology development
The core geospatial ontologies have been result of eight years of Research and Development at Image Matters in the domain of geospatial semantic. Image Matters
decided to release these ontologies for the broad community seeking to facilitate semantic interoperability between systems using geospatial information. The logical next steps are
a critical review of the provided ontologies and the application of necessary refinements and extensions to achieve a comprehensive set of base ontologies. To favor the adoption
of the geospatial ontologies, improve the robustness and completeness of the microtheories, we suggest for the next testbed exercising the ontologies by converting
existing geospatial data into geospatial knowledge, creating catalogs for unit of measures, CRSs and feature types for gazetteers. The ontologies can also be exercised by creating
ontologies for more specialized domain that leverage the core geospatial ontologies, as it was done for this testbed for EDM. The result of these activities should lead to
identifying best practices and provides a rich set of examples how geospatial ontologies could be used for different vertical communities and be queried using open linked data
standards and protocols Linked Data Platform, GeoSPARQL.
1.4.2 GeoSPARQL 2.0
Based on feedback from the OGC Geospatial Semantic WG and lessons learned from Testbed-10, there is a need to modularize and simplify GeoSPARQL specification. The
Testbed-10 geospatial ontologies address many of these aspects for example modularization of spatial relations, and could be used as a starting point.
The next testbed should demonstrate the feasibility and robustness of the approach by implementing the specifications.
