Hi Richard
Did another couple of tests and the problem is not really related to
SERVICE.
This time, I issued the following query directly to D2R-Server:
SELECT * WHERE { ?document <
http://www.cipe.accamargo.org.br/ontologias/h2tc.owl#documentAuthor>
?author . } limit 5
The results for ?author are still hex-coded. However, take a look on
map:documentAuthor:
map:documentAuthor a d2rq:PropertyBridge;
d2rq:belongsToClassMap map:Document;
d2rq:property :documentAuthor;
#d2rq:refersToClassMap map:User;
d2rq:join "documents.responsible = users.user_id";
d2rq:uriSqlExpression "CONCAT('
http://www.cipe.accamargo.org.br/ontologias/h2tc.owl#users',if(
users.universal_id is null, concat('EHR',users.user_id),
concat('UNIV',users.universal_id) ) )";
.
Does this point to something?
thanks!
