Chris,

I just wanted to let you know that the Parliament [1] triple store (a =
triple store that is built with a Jena interface) has a mostly complete =
implementation of GeoSPARQL.  We have implemented the property functions =
and filter functions for GeoSPARQL on top of our existing spatial index. =
 For more info, you can check out [2]. =20
