I like the sound of this, like an object graph of data from OSM. > I am not sure how well this type of system could work in open street map. Is it too rigid? Or would there be too much proliferation of types? Classification is always hard and I am not sure people have solved that problem in any large context. Ontologies are well-researched. Unfortunately they're not my area of expertise as I turned away from doing a PhD in them and went into business. I have been playing with a controlled vocabulary since Christmas for a personal project and the complexity of definition has made me think this is why Google et al have gone for a more flexible, machine-learned typing, and why the types for schema.org are so broad. Having been negative, I think this is exactly what OSM needs to organise the world's objects.
