Folks- FWIW, I have now reimplemented and relaunched http://www.t4gm.infoas an unpublished linked data resource, with its behavior largely consistent with the discussion on this thread. The new site links to a Github repository https://github.com/bradleypallen/t4gm-unpublished, and the CKAN Data

Tim- OK, I'm game. I am in the process of hacking together a small redirect server that would replace the existing site, and can easily incorporate the ability to return something like the following on a request for the root resource: @prefix rdf: http://www.w3.org/1999/02/22-rdf-syntax-ns# .

Antoine- Thanks for the pointer to the previous discussion, which I regret to say I had missed; the use case is almost the same and it is an approach that yields a softer landing in those cases where people/agents have been dependent on the resources being sunsetted. So I'm going to instead follow

Back in 2009, as an experiment in working with RDFa and linked data, I created t4gm.info. It is based solely on US Library of Congress library linked data (specifically, the Thesaurus for Graphical Materials), which at the time I created the site didn't have any equivalently accessible linked

Basically what you are saying is: if I have a single URI that responds to an HTTP GET with (X)HTML+RDFa by default, and supports other RDF serializations through content negotiation, then all of that can be done without recourse to a 303 redirect and should be perfectly compatible with linked data
