Well spotted. Since the WHERE keyword is optional in SPARQL queries, and ?zWHERE is a perfectly valid variable name, you wouldn't get only two bindings but your third column would be empty.
Can you please check this, Carlo? Barry On 13/03/13 20:17, Jacek Malec wrote:
Hello! Maybe I miss something but I don't see the trailing space after ?z in the query (yielding effectively ?zWHERE ...). Can this be the reason for such behaviour?

Since you don't seem to intend to reload your data every time you run your code, however, it seems that what you wanted was the 'connect to remote repository' part of that code rather than the 'create a new in process repository' part. I'd suggest to create a repository under Tomcat, convince yourself of the query results (using the Workbench, or using GNU tool and scripting as I did), then debug your Java. Your Java is simply using the Sesame API (nothing OWLIM specific) to talk to OWLIM over the same HTTP API that I'm using. Barry On 13/03/13 19:12, Carlo Allocca wrote:Yes of course I do believe.

Based on (unzipped) Tomcat 7 and OWLIM 5.3.5853, and creating Carlo.ttl based on editing getting-started/owlim.ttl (I simply set the repositoryID to "Carlo"), this is all I did: $ cp owlim-se-5.3.5853/sesame_owlim/*.war apache-tomcat-7.0.22/webapps/ $ apache-tomcat-7.0.22/bin/startup.sh $ curl -T Carlo.ttl -H "Content-Type:text/turtle" localhost:8080/openrdf-sesame/repositories/SYSTEM/rdf-graphs/service?graph=http://example.com/Carlo $ curl -T WoRMS.nt -H "Content-Type:text/plain" localhost:8080/openrdf-sesame/repositories/Carlo/statements $ diff \<(curl -sH "Accept:text/csv" -d "query=SELECT ?z {<WoRMS:159343/Thunnus_atlanticus> a ?z}" localhost:8080/openrdf-sesame/repositories/Carlo) \ <(curl -sH "Accept:text/csv" -d "query=SELECT * {<WoRMS:159343/Thunnus_atlanticus> a ?z}" localhost:8080/openrdf-sesame/repositories/Carlo)Conclusion: There's no difference between those two queries.

One can either instantiate a repository these with using GettingStarted.jar (which will also help you load ontologies and data), or can push it directly to your live Sesame endpoint over its HTTP interface with curl (my preference).BarryOn 07/03/2013 13:33, Carlo Allocca wrote:DearAll,it is again me.
