2 years ago Hi @bfrichet3
W3C DCAT v2 states the following (https://www.w3.org/TR/vocab-dcat-2/#Class:Location)
- For an extensive geometry (i.e., a set of coordinates denoting the vertices of the relevant geographic area), the property locn:geometry [LOCN] SHOULD be used.
- For a geographic bounding box delimiting a spatial area the property dcat:bbox SHOULD be used.
So IMHO loc:geometry should not be used for bounding box, only for the exact geometry (which is most likely not a box...)
I'd prefer to use WKT as recommended format (IIRC GeoJSON is limited to WGS84 only), not sure if we should explicitly exclude GML
Dear @barthanssens
I hope you are all right. I have a question about the attributes of the dct:Location class. As far as I know there are no specifications about that in the DCAT AP documents.
I noticed Flemish region seems to use loc:geometry in order to specify the bouding box of the descirbed resource. I noticed that other people use dcat:bbox too. Do you have any preferences or do you suggest us to use them both. Moreover in both cases I noticed that bouding boxes were specified by their expression in GML/WKT/GeoJSON. All these formats were identified by their opengis ID except GeoJSON which was identified by his IANA ID. Which ID would you suggest?
