    7  * === How  to connect multiple semantic systems, some using [http://www4.wiwiss.fu-berlin.de/bizer/D2RQ/spec/#specification D2R] and some purely semantic : ===
    8 
    9    * learn basics of D2RQ mapping language, modify the mapping file that you probably created using generate-[[BR]]mapping.  This is probably the file that lives in molgenis_distro (generated by d2rq) : WebContent/WEB-INF/molgenis-rdf-mapping.n3

    67    * Instead of mapping the column to a literal with !d2rq:column, use a !d2rq:uriPattern that produces URIs that match the URIs in the other dataset.
