[jira] [Created] (MARMOTTA-541) KiWi SPARQL: support for MINUS

Sebastian Schaffert created MARMOTTA-541:
--------------------------------------------

             Summary: KiWi SPARQL: support for MINUS
                 Key: MARMOTTA-541
                 URL: https://issues.apache.org/jira/browse/MARMOTTA-541
             Project: Marmotta
          Issue Type: Sub-task
          Components: KiWi Triple Store
            Reporter: Sebastian Schaffert
            Assignee: Sebastian Schaffert
             Fix For: 3.3.0


Support the SPARQL MINUS construct (opposite of UNION). In SQL, the equivalent is EXCEPT, so it could probably be implemented like UNION.
