Can one specify the source from outside the RML document? #180

RML describes a map of a schema of data to RDF. As such it should not be required that the mapping point to the data that needs to be mapped. It should be possible to do it from the command line tool., from headers (as in csv served over the web), etc... That would make it easier to re-use the same mapping file for dataset instances.

I find this useful using csv2rdf 

csv2rdf -t all_data.very_short.csv \
    -u all_data.csv-meta.json -m minimal

Perhaps that is possible, but I could not find it explained.

Hi @bblfish,

This seems like a duplicate of https://github.com/RMLio/rmlmapper-java/issues/161 Can you check the answer to that issue?
