Dear list,

I would like to ask your feedback on the use of GeoJSON as an RDF
literal in GeoDCAT-AP, a metadata profile based on and compliant with
the W3C Data Catalog Vocabulary, meant to define RDF bindings for
INSPIRE / ISO 19115 metadata.

Now, the XSLT implementing the current GeoDCAT-AP specification maps
the bounding box in the original ISO 19139 record to multiple
encodings - namely, WKT, GML and GeoJSON - specified as RDF literals
with property locn:geometry [1].

To type these literals, we use the datatypes defined in GeoSPARQL for
WKT and GML. However, as far as I know, there's no RDF/XML datatype
for GeoJSON. So, for the moment the adopted solution is to use for
this purpose the GeoJSON IANA media type.

You can find a detailed example in the XSLT documentation (Section:
"Geographic bounding box"):

https://webgate.ec.europa.eu/CITnet/stash/projects/ODCKAN/repos/iso-19139-to-dcat-ap/browse/documentation/Mappings.md#mapping-bbox

Could you please provide your advise?

BTW, GeoDCAT-AP is currently available for public review until the end
of August:

Your feedback would be more than welcome!

Thanks!

Andrea
