Is there any resource that summarizes geospatial capabilities in modern Triplestore implementations? In particular, I'm looking for a Triplestore that:
- Supports the import of geometrics in some standard format (preferably Well-Known Text [1]) - Supports RDF data types corresponding to OpenGIS Simple Features [2] (including lines, polygons, and multipolygons—not just points) - Provides SPARQL extensions for geospatial operations I'm aware of support for subsets of these capabilities in particular triplestore implementations ([3], [4]). But so far I have not found a triplestore implementation that fully meet these needs. Thanks, Jamey 1: http://en.wikipedia.org/wiki/Well-known_text 2: http://en.wikipedia.org/wiki/Simple_Features 3: http://www.openlinksw.com/dataspace/oerling/weblog/Orri%20Erling%27s%20Blog/1587 4: http://www.ontotext.com/owlim/geo.html
