Note about geographic data

[nichtich]

Geographic data is included in JSKOS via location. A place or region can be expressed as resource with location or the location can directly be attached to another resource with field location. JSKOS references GeoJSON for details, this is most practical in web application. For RDF or similar applications, geographical data may needed to be transformed from GeoJSON to other forms.

• Map to RDF property geo:asGeoJSON as specified in context.json. All data is and keep JSON
• Use GeoJSON-LD to map to GeoJSON ontology
• Map to other RDF forms by other means, e.g. plain WGS85 properties for points with latitude and longitude. GeoSPARQL should help here as well.

In summary this is all beyond specification of JSKOS but some notes and guidelines may help for interoperability still. I think for reuse of RDF data from JSKOS it would be more convenient to convert GeoJSON to WKT and provide both geo:asGeoJSON and geo:asWKT.
