Richard, how complete now is the D2RQ implementation of R2RML 'execution' (enactment?) ?

You may have caught MusicBrainz' announcement of RDF/SPARQL support at: http://linkedbrainz.org/

This mapping is effected using R2RML: https://github.com/LinkedBrainz/MusicBrainz-R2RML
and more than one RDB-mapping implementation is using these definitions for test, including Ultrawrap (used at MusicBrainz to produce the LinkedBrainz dump) and OBDA Semantika (see the latest 1.1.5 release notes).

I'd be very keen to try out the mappings using D2RQ if this is now feasible..

Cheers,

Barry

Hi Katerin,

The unreleased R2RML-compatible version of D2RQ can generate R2RML mappings from the schema of an existing database.

You can find it as "d2rq-r2rml-preview-v4" here: http://download.d2rq.org

Use it like this:

    ./generate-mapping --r2rml -u user -p password jdbc:mysql://localhost/mydatabase

There is (currently incomplete) documentation in the /doc directory of the download.

The *very* latest version of that code, which may have more recent bugfixes, is available in the project's "develop" branch on GitHub: https://github.com/d2rq/d2rq

Hope that helps,
Richard
