sparqlmap seems to bloat generated turtle file (action=dump)

[k00ni]

Version: https://github.com/tomatophantastico/sparqlmap/releases/tag/v0.7.5-SNAPSHOT-2

Input CSV: https://github.com/AKSW/transform-bvl-pages-to-csv-file/blob/master/le-online-extracted-places.csv

Mapping: https://github.com/AKSW/transform-bvl-pages-to-csv-file/blob/master/r2rml-mapping.ttl

The TTL output file is about 60 MB.

But after running

rapper -i turtle -o turtle ~/Docker-Containers/sparqlmap/data/output.ttl >! ~/Downloads/output.ttl
rapper: Parsing URI file:///home/k00ni/Docker-Containers/sparqlmap/data/output.ttl with parser turtle
rapper: Serializing with serializer turtle
rapper: Parsing returned 402426 triples

the output file shrinks to about 9 MB. File seems to have way less triples as the one generated by sparqlmap.

rapper -i turtle -c ~/Downloads/output.ttl                            
rapper: Parsing URI file:///home/k00ni/Downloads/output.ttl with parser turtle
rapper: Parsing returned 67071 triples

I reproduced the behavior of rapper with CMEM from eccenca. Uploaded the 60 MB turtle file as a new graph, but downloading it resulted in a file around 9 MB.

Any idea?
