RDF::RDB2RDF::R2RML - map relational database to RDF using R2RML
my $mapper = RDF::RDB2RDF->new('R2RML', $r2rml); print $mapper->process_turtle($dbh);
This class offers support for W3C R2RML, based on the 29 May 2012 working draft. See the COMPLIANCE AND COMPATIBILITY section below for a list on unimplemented areas.
This is a subclass of RDF::RDB2RDF::Simple. Differences noted below...
A single parameter is expected, this can either be an R2RML document as a Turtle string, or an RDF::Trine::Model containing R2RML data. If a Turtle string, then the namespaces from it are also kept.
The mapping is included as an R2RML comment at the top of the Turtle. Passing
no_r2rml => 1 can disable that feature.
This implementation should be mostly compliant with the Direct Mapping specification, with the following provisos:
Other quirks are database-specific:
