Hi Adrian, The Virtuoso DEFINE input:same-as “yes” pragma can be use for the owl:sameAs relation ie
DEFINE input:same-as "yes" DESCRIBE
<http://lod.opentransportdata.swiss/didok/BSGB>
as detailed at:
http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtSpongerLinkedDataHooksIntoSPARQL#SQL
Pragmas
<http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtSpongerLinkedDataHooksIntoSPARQL#SQL%20Pragmas>
Which gives:
http://lindas-data.ch/sparql?default-graph-uri=&qtxt=DEFINE+input%3Asame-as+%22yes%22%0D%0A%0D%0ADESCRIBE+%3Chttp%3A%2F%2Flod.opentransportdata.swiss%2Fdidok%2FBSGB%3E&should-sponge=&format=text%2Fhtml&timeout=0&debug=on
