Your suggested implementation looks excellent, and will work well for us.
I have made some changes to the apache configuration for bbc-programmes.dyndns.org, so it now behaves like this.
Although I still need to sort out the Content-Location and Vary: Accept headers.

The RDF views are not intended to expose exactly the same as the HTML views.
The RDF views and URIs are much closer to how the data is modelled in the database.

I have added a foaf:primaryTopic triple.

Thanks for your feedback :)

Nicholas,

I think it would be best to implement the mechanism described here:
http://www.w3.org/TR/cooluris/#hashuri

This would mean:
<b00b07kw#episode> is the thing
<b00b07kw.rdf> is the RDF variant
<b00b07kw.html> is the HTML variant
<b00b07kw> is a generic, content-negotiated document; it serves the  
right variant directly, without any redirect, and gives the URI of the  
selected variant in the Content-Location header.

It appears that the HTML version provides much more information than  
the very brief RDF version, or am I just not finding most of the RDF?

Other minor things:

<bb0b07kw> should have a "Vary: Accept" header to indicate that the  
resource is subject to content negotiation; otherwise caches can  
become confused

A triple "<bb0b07kw> foaf:primaryTopic <bb0b07kw#episode>" would be  
very helpful for RDF browsers.

Best,
Richard
