Re: Question on "moving" linked data sets

Hello Antoine

My take on this would be to use dcterms:isReplacedBy links rather than
owl:sameAs
Description of the concepts by BNF might change in the future and although
the original identifier is the same, the description might be out of sync
at some point.
