Ontology for spatial referencing by geographic identifiers #447

Open MortenBorrebaek opened 2 years ago

MortenBorrebaek commented 2 years ago

n the AHG on e-Government recommendations were made for the future revision of ISO standards and new standard projects: -ISO/TC 211 should continue to derive RDF/OWL from the harmonised UML models in the ISO/TC 211 standards. Existing activities on revising mapping rules from UML to OWL/RDF will improve the ontology and mapping rules should be an ongoing activity, according to experience from the communities. In addition, ISO/TC 211 should link to existing vocabularies and extend other vocabularies applied in e-Government with our spatial extensions where needed.

-In the revision cycles of ISO/TC 211 standards, focus should be given to investigate if there are other and more generic IT standards which it would be relevant to build geospatial extensions on top of. Of particular focus are standards from ISO/IEC JTC1 and W3C, which are most focused in e-Government communities. This comes as an extension to the cooperative work between ISO/TC 211 and OGC .

For ISO 19112 the following was discussed: Geographic identifiers are an essential element in many e-Government datasets.

ISO 19112 specifies the transition from geographic identifiers to precise coordinates. The question is how to resolve this transition in the e-government domain, where these data are available as vocabularies?

Consider if there is a need for an annex in ISO 19112 describing how to use OWL/RDF and ontologies in relation to 19112.

Transition from identifiers to coordinates is indeed the subject of ISO 19112, perhaps most obviously as a 'gazetteer' (a register of locations). I don't see that ISO 19112 provides any "platform specific" implementation of that - would it be helpful to standardise how to publish a gazetteer on RDF? We haven't provided any 'how to publish a gazetteer' standard before.

At a more abstract level, there is some call from OGC/W3C SDWWG to have a formal OWL statement of things like "the relation between a location & its representative position in coordinates" - but in that case, an ISO 19112 Location is no different from any other ISO/OGC Feature instance- it "has a representative geometry" (in a CRS)
