You could also abuse Python's namespaces:

    def rdf_model(...):
        ...

    globals()['rdf-model'] = rdf_model

Using _q_lookup is probably the cleanest.  Something like:

    def _q_lookup(request, component):
        if component == 'rdf-model':
            return ModelDispatch(...)
        ...

If you don't want to treat some names specially, you could have a
standard pattern:

    def rdf_model(...):
        ...

    ...

    exports = {
        'rdf-model': rdf_model,
        'hello_world': hello_world,
        ...
    }

    def _q_lookup(request, component):
        return exports.get(component)

That last bit is untestest but should work.  Returning None from
_q_lookup signals a non-existent component, if I recall correctly.
