GeoSpatialLiteralExtension.java supports storing coordinates as http://www.bigdata.com/rdf/geospatial#geoSpatialLiteral type. We want to create an extension to store them from the format described in https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format#Globe_coordinate, e.g. "Point(12.93 35.3)"^^geo:wktLiteral
This extension would support converting these literals into internal indexable format and back.
