Because RDF statements exist in an Open World, there is nothing stopping those two statements from existing at the same time. This is because the web doesn't prohibit any particular assertion. On the web, it can be said that I'm a dog and a man. :) Having said that, I've gotten around this problem in my applications by moving my application context from one graph to another. If I decide that John's height is now 70, I assert that in a new graph, and then move my application to that one. Not pretty. This might be solved a little nicer when people start working on trust mechanisms for RDF. SethReceived on Wednesday, 25 June 2003 11:00:42 GMT
