Hi Kjetil

You might be interested by what has been done for lingvoj.org language URIs
(which you have used in a project if I remember well) redirected now to
lexvo.org. See http://www.lingvoj.org/

There are not many explanations of the rationale and method, but your
message reminds me it's on my to-do list to document it further.

At http://www.lingvoj.org/lingvo/fr.rdf you get the following descriptions

    <rdf:Description rdf:about="http://www.lingvoj.org/lingvo/fr.rdf">
        <dcterms:isReplacedBy rdf:resource="
http://www.lexvo.org/data/iso639-3/fra"/>
    </rdf:Description>

Provides the RDF document replacing the current one

    <lingvoj:Lingvo rdf:about="http://www.lingvoj.org/lang/fr">
        <rdfs:isDefinedBy rdf:resource="
http://www.lexvo.org/data/iso639-3/fra"/>
        <owl:sameAs rdf:resource="http://lexvo.org/id/iso639-3/fra"/>
    </lingvoj:Lingvo>

Provides the new URI and the new document where it is defined.

Re. conneg, I've set up a simple redirect for the html pages.

I of course welcome any feedback about this method.

Best

Bernard
