I have what I think may be a common problem and am looking for suggested
patterns and anti-patterns for a solution.
For the sake of this example let's assume that the system described creates
FOAF records.
== PROBLEM
Backend:
The backend system generates FOAF records but does not have any information
about where they will be stored/deployed. So it generates records like
<urn:mysystem:foaf1> a foaf:Person ;
foaf:name "Jimmy Wales" ;
foaf:mbox <mailto:[email protected]> ;
foaf:homepage <http://www.jimmywales.com> ;
foaf:nick "Jimbo" ;
foaf:depiction <http://www.jimmywales.com/aus_img_small.jpg> ;
foaf:interest <http://www.wikimedia.org> ;
foaf:knows <urn:mysystem:foaf2> .
<urn:mysystem:foaf2> a foaf:Person ;
foaf:name "Angela Beesley" .
This data is stored in a Fuseki based server.
Frontend 1:
The front end should take replace the <urn:mysystem> based URIs with http
based URIs that point to the frontend. So assuming the frontend is at
http://frontend:8080 and has a method to return RDF in turtle format the
RDF should look like
<http://frontend:8080/foaf1> a foaf:Person ;
foaf:name "Jimmy Wales" ;
foaf:mbox <mailto:[email protected]> ;
foaf:homepage <http://www.jimmywales.com> ;
foaf:nick "Jimbo" ;
foaf:depiction <http://www.jimmywales.com/aus_img_small.jpg> ;
foaf:interest <http://www.wikimedia.org> ;
foaf:knows <http://frontend:8080/foaf2> .
<http://frontend:8080/foaf2> a foaf:Person ;
foaf:name "Angela Beesley" .
Frontend 2:
There is a second frontend with a different URL. http://frontend2:8080,
frontend 1 and frontend 2. Frontend 2 does not have access to frontend 1
(assume that there is a firewall that prohibits the access). Frontend2
should produce RDF like:
<http://frontend2:8080/foaf1> a foaf:Person ;
foaf:name "Jimmy Wales" ;
foaf:mbox <mailto:[email protected]> ;
foaf:homepage <http://www.jimmywales.com> ;
foaf:nick "Jimbo" ;
foaf:depiction <http://www.jimmywales.com/aus_img_small.jpg> ;
foaf:interest <http://www.wikimedia.org> ;
foaf:knows <http://frontend2:8080/foaf2> .
<http://frontend2:8080/foaf2> a foaf:Person ;
foaf:name "Angela Beesley" .
== Question
How can I setup a system that will automatically convert one URI to another
without storing multiple copies of the data (e.g. not multiple datasets).
I have thought about using owl:sameAs and am wondering if there is a
reasoner that will process it.
Anyway, has anyone else come across this problem (I figure so) and does
anyone have a possible solution?
Thx,
Claude
