Well... I do not find GeoSPARQL (in toto) very useful to me. However "Simple Features" (http://schemas.opengis.net/sf/1.0/simple_features_geometries.rdf#) is. I'll reuse sf:Polygon and sf:Line.
Problems: 1. I miss "Circle". 2. WKT is not very attractive :-( 3. I need "elevation" for the points (surfaces on slope). Besides, I expect schema.org to be more popular in the next years :-) Dan PS.
