Generating metadata in different RDF format

[AurisAudentis]

When specifying both a metadata file (-e option) and a format option (-s) the application crashes.

The following command works:
java -jar rmlmapper-4.8.0-r247.jar -m mapping.rml.ttl -s turtle

The following command does not work:
java -jar rmlmapper-4.8.0-r247.jar -m mapping.rml.ttl -s turtle -l triple -e metadata.turtle
and instead outputs:

Exception in thread "main" java.lang.Error: Serialization turtle not supported at be.ugent.rml.store.SimpleQuadStore.write(SimpleQuadStore.java:97)  
at be.ugent.rml.cli.Main.writeOutputUncompressed(Main.java:413)

I was able to work around this issue by changing the used store of the MetadataGenerator to RDF4JStore here:

rmlmapper-java/src/main/java/be/ugent/rml/metadata/MetadataGenerator.java

Line 54 in fb2d8d7

mdStore = new SimpleQuadStore();

Thanks! Will have a look at it.
