AskOmics need the Virtuoso triplestore to work.

Compile virtuoso

or install via docker

docker pull askomics/virtuoso

docker run --name my-virtuoso \                                                                                                                              
    -p 8890:8890 -p 1111:1111 \
    -e SPARQL_UPDATE=true \ 
    -v /tmp/virtuoso_data:/data \         
    -d askomics/virtuoso
