MapView seems not working for relations

[sun-geo]

Based on example:
https://wiki.openstreetmap.org/wiki/SPARQL_vs_Overpass_QL_examples#Nodes_and_ways_with_a_given_key
i did modify the query a bit to find relations with key educational=* (wiki):

MapView seems not working, see:

As comparison Sophox works well:

it maybe doesn't work for WKT literals of type GEOMETRYCOLLECTION yet?
@patrickbr or @hannahbast ?

[patrickbr]

Indeed, GEOMETRYCOLLECTIONs are not supported so far. We are working on it :)

@LorenzBuehmann Can you post the corresponding query for sophox.org?

Hi Hannah and Patrick!

Well, it's not my query, but the Sophos link above leads to standard Blazegraph UI. On the right-hand side of that UI there will popup some overlay menu, when you click on "Edit code" there, you'll get to the query editor:

So the query in Sophox will be

#defaultView:Map
SELECT * WHERE {
  VALUES ?types { "r" }
  ?osmId osmm:type ?types;
         osmt:educational ?key;
         osmm:loc ?loc.
}

Ok, so it sounds like an "easy" to fix limitation somehow? Not sure, you probably already cover LINESTRING and POINT and POLYGON? What about the MULTI* representations of those? I mean those are simply containers of each type, so a bit more restrictive than the GEOMETRYCOLLECTION.
