   Does Jena support GeoSPARQL 1.1?
   I've looked at docs and javadocs (but not the source!) and they suggest it 
supports 1.0 but not 1.1:
   - https://jena.apache.org/documentation/geosparql "An RDF/XML schema has 
been published for the GeoSPARQL v1.0 standard"
   - 
https://jena.apache.org/documentation/javadoc/geosparql/org.apache.jena.geosparql/module-summary.html
 shows 1.0 terms (eg WKT, KML) but not 1.1 terms (eg KML).
   - It shows GeoJSON (which is 1.1) but that is listed in 
https://jena.apache.org/documentation/geosparql/#future-work
   - 
https://jena.apache.org/documentation/javadoc/geosparql/org.apache.jena.geosparql/org/apache/jena/geosparql/geof/nontopological/filter_functions/package-summary.html
 doesn't show the standard functions, eg `area` (1.0), `metricArea` (1.1). But 
search eg for "distance", there are many non-standard functions
   - https://jena.apache.org/documentation/geosparql/#units-uri is good 
documentation (the OGC spec didn't even list what . But 1.1 added "metric" 
functions (where the unit is fixed to meters, and are guaranteed to work for 
metric CRS @MathiasVDA ) and I think this section should mention them
   
   I also looked at existing issues:
   - https://github.com/apache/jena/issues/3593 doesn't mention that
   - https://github.com/apache/jena/issues/3717 is not it
   
   Even if Jena has partial support for 1.1, it'd be extremely valuable to 
document exactly which .1 features it supports
   - it seems to me that https://jena.apache.org/documentation/geosparql needs 
to be updated.
   - this can also be stated in RDF, let me know and I'll dig out the OGC 
conformance turtles

   @situx what is the status of https://github.com/i3mainz/jena-geo? 
   - It's 6y old, does it implement GeoSPARQL 1.1?
   - Are there plans to merge it into Jena?
   
   Thanks for any info!
