About

See the Data2Services documentation to run RdfUpload as part of workflows to generate RDF knowledge graph from structured data.

This project uploads a RDF file into a specified SPARQL endpoint. It is possible to optionally define username and password.

Docker

Build

docker build -t rdf-upload .

Usage

docker run -it --rm rdf-upload -?

Usage: rdfupload [-?] [-ep=<endpoint>] -if=<inputFile> [-pw=<passWord>]
                 -rep=<repository> [-uep=<updateEndpoint>] [-un=<userName>]
                 -url=<url>
  -?, --help   display a help message
      -if, --inputFile=<inputFile>
               RDF file path
      -pw, --password=<passWord>
               Password used for authentication
      -rep, --repositoryId=<repository>
               Repository ID
      -un, --username=<userName>
               Username userd for authentication
      -url, --database-url=<uri>
               URL to access GraphDB (e.g.: http://localhost:7200)

Run

  • Linux / OSX
# RDF4J server URL + repository ID
docker run -it --rm -v /data/rdfu:/data rdf-upload -if "/data/rdf_output.ttl" -url "http://localhost:7200" -rep "test" -un USERNAME -pw PASSWORD

# Upload multiple files with full SPARQL endpoint URL 
docker run -it --rm -v /data/rdfu:/data rdf-upload -if "/data/*.ttl" -url "http://localhost:7200/repositories/test" -un USERNAME -pw PASSWORD
  • Windows
docker run -it --rm -v c:/data/rdfu:/data rdf-upload -if "/data/rdf_output.ttl" -url "http://localhost:7200" -rep "test" -un USERNAME -pw PASSWORD

Preload

docker run -d --rm --name graphdb -p 7200:7200 \
  -v /data/graphdb:/opt/graphdb/home \
  -v /data/graphdb-import:/root/graphdb-import \
  graphdb

Issue: GraphDB needs to be stopped when running the load tool. Killing the java process stop the container

Try without the --rm flag

/opt/graphdb/dist/bin/preload -f -i <repo-name> <RDF data file(s)>

preload -f -i test /data/graphdb-preload/biogrid_dataset.ttl


docker run -it -v /data/graphdb:/opt/graphdb/home -v /data/graphdb-import:/root/graphdb-import --entrypoint "/opt/graphdb/dist/bin/preload -f -i test /opt/graphdb/home/data/rdf_output.nq" graphdb

# Not failing, but nothing load when docker start graphdb
docker run -it -v /data/graphdb:/opt/graphdb/home -v /data/graphdb-import:/root/graphdb-import --entrypoint /opt/graphdb/dist/bin/preload graphdb -c /root/graphdb-import/repo-config.ttl /opt/graphdb/home/data/rdf_output.nq

# Create repo test using config file. Works but GraphDB should not run
docker exec -it graphdb /opt/graphdb/dist/bin/preload -c "/root/graphdb-import/repo-config.ttl" "/opt/graphdb/home/data/rdf_output.nq"
# Use existing test repo
docker exec -it graphdb /opt/graphdb/dist/bin/preload -f -i test "/opt/graphdb/home/data/rdf_output.nq"
