Handle inverse expressions? #8

Open patrickwestphal opened 10 years ago

patrickwestphal commented 10 years ago

Currently rr:inverseExpressions are not considered during R2RML-to-SML conversion. Do they need consideration at all? How can they be translated?

Aklakan commented 10 years ago

Inverse expressions are not yet part of SML. We could do something like

    ?s = uri(?col) with inverses
        ?foo As "split(?col, '---')[0]", ?bar As "split(?col, '---')[1]"

Note that ?foo = "..." would conflict with ordinary var definitions.
