- GraphDB doesn't support GeoJSON. Please use WKT.
I am not sure how much WKT is used in the Geospartial comunity. The thiniking is that the GeoJSON data is generated from a GIS. Until GraphDB support GeoJSON, I do not see a big issue in converting the GeoJSON to WKT.

I am not sure how much WKT is used in the Geospartial comunity.
Is this comment based on some observations?
Here are some facts:
Hi @Sveino!
Investigate the possibility to use GeoJSON(-LD) as a replacement for GeographicalLocationProfile described in IEC 61968-13:2021.
We would to use JSON-LD since this could be the first step to create IEC 61970-553 that describe how JSON-LD should be used for exchanging RDFS based profiles (IEC 61970-450-series and IEC 61968-13).
We would also like to be complaint with the latest version of GeoSparql v1.1: https://opengeospatial.github.io/ogc-geosparql/geosparql11/spec.html Relevant issue: https://github.com/opengeospatial/ogc-geosparql/issues/1 https://www.ogc.org/standards/geosparql
