Re: Question on "moving" linked data sets

In fact it seems that the dcterms:replaces option considers two resources

Indeed. The "bnf" resource replaces, by all means of the term, the "stitch"
one.

There I don't follow you. Let's say I have both URIs stitch:x and bnf:y.
They both identify resources, which happen to be instances of skos:Concept.
When I read   stitch:x  dcterms:isReplacedBy   bnf:y
I understand : Whenever you used the resource stitch:x (in your linked
data, vocabularies, index ...), please now use bnf:y.
That does not mean only change dumbly the URI in your application, but it
means also that if you want to figure the current definition of the
concept, trust what you'll find when you dereference bnf:y. It might be
strictly the same description as was once found at stitch:x, or it might
have changed (for example this concept has been moved in the RAMEAU
hierarchy, or its label or definition slightly modified etc). And since
from stitch side you don't know about it, you can't assert any owl:sameAs
for sure. BNF description can keep owl:sameAs links to assert that indeed
for this very concept, the semantics has not changed since stitch, and get
rid of this sameAs if ever the concept changes.
Actually, quite a lot of RAMEAU concepts have changed since stitch
publication. Maybe (certainly) some concepts present in stitch are not
present any more in RAMEAU. In that case the bnf:y would be 404 and it's
OK. It means stitch:x has been replaced by nothing in bnf namespace.
Of course, this does not look as a good practice, but I'm afraid it justs
shows the plain fact that RAMEAU has not (yet) a clean depreciation
mechanism, unless I miss recent developments (Romain can correct me if I am
wrong). I'm sure it will have some day soon :)
