Dear all, here come my comments about the GeoSPARQL specification.

There is a typo in item which described LineString class, there 
is the name Curve instead of LineString in the URI identifying the resource

In t he SimpleFeature object from OGC we came up with the following 
questions: to what is referring the ArcString class, is the same class 
than SimpleFeature in OGC? Wht there is no class LinearRing in the 
model? Why compose relations such TIN which is composed by triangles or 
MultiPoint are not taken into account? Why envelope and boundary 
attributes are taken into account as filter function and not as class 

In general this model is widely used, Virtuoso and other implementations 
(like geometry2rdf) in general follow the same approach than the one 
described in the specification.
