How to

1- Create a 4store dump

sudo 4s-dump http://localhost:8081/sparql/ -a -o ./data

2- Convert the 4store dump to Virtuoso dump

./4s-to-virtuoso.sh ./data .

3- Import the Virtuoso dump

./import_to_virtuoso.sh <virtuoso_user> <virtuoso_pwd> "./processed_files"

4- Check if the triple count corresponds to the count in the dump files

ruby compare_counts.rb

will generate a csv called graph_comparaison.csv
