Great!
I hope it will work for you. Please tell us if anything new happens: The previous thread has shown that this issue has been faced only a few times, any experience report is welcome!

Btw if that does not require too much work it would be also useful to generate owl:sameAs statements, so that Hugh can feed them into sameAs.org. Maybe the Library of Congress would also be happy to ingest them too, so that the clients which come from your URIs get the link in RDF between these URIs they were searching for, and the new ones.

> 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 your lead and have t4gm.info <http://t4gm.info> instead respond with a 301 redirection to the equivalent id.loc.gov <http://id.loc.gov> resource when that exists, else respond with a 410 error. - regards, BPA

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 data. That has long since been rectified by the LoC. So t4gm.info <http://t4gm.info> <http://t4gm.info> is at best redundant and at worst potentially confusing.

But there doesn't seem to be much if any best practice around doing that, especially when the site by virtue of its listing with CKAN is part of the LOD Cloud diagram. What I want to do is 1) delist it from CKAN, and then 2) shut the site down, perhaps replacing it with a simple web service returning a 410 status code per RFC 2616. I assume it will be removed from the LOD cloud diagram when that is next updated from the CKAN data.
