Clone the project from github and execute:
cd intermine-R2RML-mapping
./gradlew install
./gradlew -q run > mapping.ttl # Silence gradle or it will corrupt the mapping file
This mapping.ttl file can then be used by R2RML implementations such as ontop.
If one wants to use ontop
mkdir ontop-cli
cd ontop-cli
wget "https://github.com/ontop/ontop/releases/download/ontop-4.0.3/ontop-cli-4.0.3.zip"
unzip ontop-cli-4.0.3.zip
# intermine uses postgresql so get the JDBC driver
cd jdbc
wget "https://jdbc.postgresql.org/download/postgresql-42.2.18.jar"
#make a file db.properties
jdbc.url=jdbc:postgresql://localhost:5432/biotestmine #Change to your settinggs
jdbc.user=${YOUR_PGSQL_USERNAME}
jdbc.password=${YOUR_PGSQL_PASSWORD}
#Then one can use
./ontop query -m ../mapping.ttl -p db.properties -q ../queries/proteins.rq
