SPARQL2Spark 0.0.5

SPARQL Result to Spark

This is a simple module that allows developer to query SPARQL endpoints and analyze the results with Apache Spark. In particular, if a SELECT query is used, a DataFrame is returned, while if a CONSTRUCT query is used, a GraphFrame is returned. You can find the documentation here.

Build

To generate a .whl file just type make build, and the file will be generated under dist folder.

Test

To properly test the library a SPARQL endpoint is needed. Navigate to deplyoment folder and start a Jena-Fuseky component with the command docker-compose up -d. A simple, hand made, FOAF ontology with few individuals is loaded in Jena-Fuseki. You are encouraged to experiment with the SPARQL endpoint availabe at localhost.

After starting Jena-Fuseki, navigate back to the main folder, and type make docker-test to start the test phase.
