mapping URIs
I have a case where data are generated in a backend system that is not
publicly accessible and has no idea where the data are going to be served
from.
The backend system generates URNs like "<urn:foo:bar:yeehaw>"
What I think I want to do is on the fuseki server be able to configure
"urn:foo:bar" as a place holder for "http://server:8080/yeehaw".
Now, I know I can add this as part of an OWL:sameValue but I would like to
see Fuseki do that.
In this way when the data are hosted on another system the resolution can
be adjusted appropriately.
Perhaps this does not make sense. Perhaps there is a way to do this
already. Perhaps this is a really bad idea. So I am throwing it out there
to see if there are any comments.
Thx,
Claude

Another use case is where an endpoint is known to have moved. So that if
the user attempts to resolve the data they are correctly redirected to the
new location.

actually, I want the urn:foo:bar: prefixed URLs in Jena to be converted to
http://server:8080/ on the way out so that all urn:foo:bar prefixed URNs
are resolvable by the browser.
I would then add a script at http:server:8080/ to take the path and make a
call back to fuseki to resolve the item.
However if URNs are mapped on the way out they would need to be mapped on
the way back in unelss they are simply mapped by using Owl:sameValue

<urn:foo:bar:yeehaw> -------------> <http://server:8080/yeehaw>

Claude, are you saying you want people to be able to query Fuseki using urn:foo:bar:yeehaw and get back answers using http://server:8080/yeehaw?
Otherwise, I'm guessing I'm missing something, but why wouldn't you do the substitutions on the way from the backend to Fuseki?
