A simple endpoint to expose RDF4J SPARQL repository without to much hustle
SSE allows you to deploy a RDF4J SPARQL repository using either native RDF data or a relational database and Ontop.
Build with maven
maven package
java -jar target/sse-1.0.jar file.properties
An es of properties file for the native mode is
server.name=lite
server.port=8080
base.url=http://example.org/base
file.location=src/main/resources/data.lite.ttl
file.format=ttl
named.graph=default
java -jar target/sse-1.0.jar --virtual file.properties
The virtual mode requires to point the properties file required by Ontop.
server.name=lite
server.port=8080
base.url=http://example.org/base
ontop.properties=src/main/resources/postgres.properties
ontop.owl=src/main/resources/citybench.owl
ontop.obda=src/main/resources/citybench-traffic.obda
docker build -t sse .
docker run -p —name sse-running 8080:8080 sse
I tested the service with sparql-client and SPARQLWrapper.
To run the javascript tests NPM is requried
npm install sparql-client
node app.js
To run the python test using python 3
pip install SPARQLWrapper, rdflib-jsonld
python SPARQLWrapperTestSelect.py
python SPARQLWrapperTestConstruct.py
