Javascript and Python

pat = Human()
rover = Dog() = "Pat Smith" = "Rover" = rover

We can begin to consider cardinality:

pat = Human()
rover = Dog()"Pat Smith")"Rover")

But to be more complete, we need something like this which loses the simplicity of the built-in model:

pat = Resource()
rover = Resource()
pat.addProperty(  ns.rdf.type,
pat.addProperty(, "Pat Smith")
rover.addProperty(, "Rover")
pat.addProperty(  ns.perpet, rover)
