OptiSparql 🐿️

Testsuite for SPARQL OPTIMAL queries

Installing and running the testsuite

1. Download and install Node.js. Make sure the install wizard downloads NPM as well (it does per default).
2. Clone this repository using Git: git clone https://github.com/ifis-tu-bs/optisparql.git OR download the repository using the browser and unzip it.
3. Navigate to the testsuite directory inside the project using your shell (or the Node.js Bash shell on Windows).
4. (Optional) Install the dependencies by running npm install
5. You can now start the application by running npm start

3. Copy the selected variables from orig.ql into the Selection input field
4. Copy the header information from orig.ql into the Headers textarea
5. Copy the entire content from optimal.json into the main JSON query representation textarea
6. Click Generate SPARQL Queries to create OPTIMAL encodings for your query
7. Click Test generated SPARQL queries to run the performance test
8. If everything worked out, the text above the encodings should now indicate the queries' execution times
