To create a database:

4s-backend-setup test

To start a database backend:

4s-backend test

To start a SPARQL HTTP server:

4s-httpd test

Now you can import data with:

curl -T {file} 'http://localhost:8080/data/{uri}'

{uri} should really be a URI-Escaped URI for the graph to store the data under, but you can often get away without escaping it.

And try queries at http://localhost:8080/test/. The SPARQL endpoint is at http://localhost:8080/sparql/.
