Questions/issues with metadata file #261

Description

@frmichel

When using options --metadatafile metadata.ttl --metadataDetailLevel dataset I get a description like the one below.

2 things puzzle me:

  • the description is about metadata.ttl, the is the metadata file, whereas I would expect it to be about the generated dataset, not just the metadata about which I don't care so much.
  • there is no count of triples generated with void:triples. This would be very useful, otherwise I have no way to know that information.
    Actually I can know it in verbose mode with the following trace:
    13:21:32.680 [main] INFO be.ugent.rml.cli.Main .writeOutputUncompressed(648) - Writing quads to output.ttl...
    However the log is very verbose (DEBUG mode) and I have no way to change the log level to INFO.
