ISSUE-22 (vendor specific SQL): Support for database vendor specific SQL statements. [R2RML] http://www.w3.org/2001/sw/rdb2rdf/track/issues/22 Raised by: David McNeil On product: R2RML Allow database vendor specific SQL statements to be embedded in R2RML mappings. For example, this is needed if a mapping needs to use an Oracle specific statement that cannot be parsed as standard SQL. A possible solution is to allow SQL statements to be flagged as "opaque". This would indicate that the statements are not to be parsed by the mapping tool, but simply passed down to the underlying database. I interpret this statement in section 1.3 of the R2RML spec to preclude the use of vendor specific SQL: "In places where SQL expressions are allowed, these *MUST* conform to Core SQL 2008."
