OKH RDF tripple-store tester

This contains instructions and scripts to help you easily test the OKH data with the Apache Jena triple-store.

In short, it:

1. Downloads the required software (to ~/.local/opt/apache-jena-*)
2. (backend) Creates a directory (./rdf_db/) to use as the tripple-store
3. Loads the OKH ontology and all the crawled hardware projects into the tripple-store
4. (frontend) Starts a local web-interface that allows you to run SPARQL queries on the data

Usage

# Gets this project onto your computer.
git clone "https://github.com/OPEN-NEXT/LOSH-RDF-DB-tester.git" "OKH-DB-tester"
cd "OKH-DB-tester"

# Creates the DB and fills it with the data
# (See the output for instructions
# of how to run SPARQL querries on the command-line).
# NOTE This might take quite a while to finish
./fill-db

# Starts the web-interface
# (see the output for the URL
# you will have to open in your browser)
./web-ui

The web-UI will then (probably) be available at:

http://localhost:3030/#/dataset/okh/query

You can now try your first sample query on the OKH data.
