Sport Ontology Diagram

When I was working on the BBC semantic publishing platform I was involved in the design of the BBC Sport Ontology. This has subsequently been accepted into the Linked Open Vocabularies (LOV). I thought it would be useful to draw up a full data model diagram of the ontology so it can be visualized in all its glory (it links to a big version). The diagram should be accurate with respect to the ontology RDF - if anyone spots any obvious mistakes - let me know and I will correct :)
