    Is SPARQL "OPTIONAL" supported in SEM_MATCH?

    655977
      I am using 11g and have some SPARQL statements that use FILTER and OPTIONAL clauses. I see SEM_MATCH can take filter. Does SEM_MATCH support OPTIONAL? The Jena adapter example (jenadrv_ex.java) has the SPARQL with FILTER and OPTIONAL.

      Is the Jena adaptor api implemented on top of SEM_MATCH api or SEM_MATCH on top of jena adaptor api?

      Thank you.
