Now D supports semantic Web (RDF and SPARQL particularly):

I've created a D wrapper around C semantic Web library librdf.

Here is the code (it also supports several other programming languages, particularly I did also Ada2012 wrapper, the Ada wrapper is however somehow not stable):

https://github.com/vporton/redland-bindings

See also https://codereview.stackexchange.com/q/212017/189213 about some future plans and probable some future API incompatibility.

Please participate in code review and adding more unittests.
