13.1.6 WFS-G: Update WFS-G Best Practices for WFS 2.0

It is recommended that the WFS-G BP document is updated for WFS 2.0 and the Filter Encoding Specification 2.0, both of which were released in 2009. This would allow WFS-G services to take advantage of WFS 2.0 features such as stored queries. The PropertyContains operator described in 8.2.3 is an extension of the Filter Encoding Specification 2.0 and would not be available for WFS 1.1 services.

13.1.7 Semantic Gazetteer Ontology and API

We propose to semantically-enable existing gazetteers by defining a new linked data REST API and GeoSPARQL based on the Testbed-10 Geospatial Ontology. The Geospatial Ontology will provide a solid foundation for defining a gazetteer ontology describing places of interest, toponyms and geospatial-temporal location. The gazetteer ontology should accommodate historical gazetteers, multiple geometries, multilingual requirements and different taxonomies for place types. The model will be designed to meet minimum-essential place information exchange requirements, while accommodating custom extensions using built-in extension mechanisms provided by RDFS and OWL. Places and Locations will be returned in RDF-compatible Linked Data formats RDFXML, Turtle, JSON-LD, NTriples. This will also support the linking of place instances to other relevantrelated information DBPedia, Geonames, Social Media, etc. by leveraging standard Semantic Web technologies RDF, HTTP, URLS. The testbed should demonstrate the feasibility and robustness of the resulting Semantic Gazetteer and candidate specification by testing one or more implementations.

13.1.8 Standardization of the core geospatial ontologies

Core geospatial ontologies should be standardized, so people can use them to expressed their geographic data as linked data.

13.1.9 Best practices to publish geospatial linked data

Best practices to publish geospatial linked data use of GeoSPARQL, RDF, OWL, Linked Data Best practices should be defined.

13.1.10 Cleanup of the GeoSPARQL standard
