I’ve had an initial stab at encoding the RCC8 spatial relations as an ontology. This is probably actually more RCC6 as I collapsed the TPP/NTPP and TPPi/NTPPi relations down to simpler properties. The ontology here is an extension of the spatial relations ontology I wrote for work. I’ve tried to capture as many property compositions as possible using OWL. Here is an example including the data for Hampshire to show some of the reasoning in action. As with the Allen Interval algebra ontology this is not a complete axiomatisation of the RCC8 relationships (not possible in OWL), but hopefully has some use. Again feedback appreciated…

I could add there are a few RCC8 reasoners (including http://pypi.python.org/pypi/PyRCC8/ http://clarkparsia.com/pellet/spatial/ http://www.racer-systems.com/products/racerpro/features.phtml) that do RCC8 out of the box, but I thought it would at least be an interesting exercise to see how much could be captured in OWL.
