SPARQL Endpoint

• Goal :

  How to create a SPARQL enpoint using Apache Jena Fuseki & Heroku
  

  ---

• Prerequistes:- Basic understanding of Git, Heroku & command line or powershell or terminal

• Step 1:- Clone this repo in your local system using command

  git clone https://github.com/swinton/fuseki-heroku
  

  (make sure to install git in your system from here )

• Step 2:- Copy your RDF / Knowledge graph in the /Data/ folder (make sure to delete all other extra RDFs from that folder) for reference check below screenshot, I have added product.ttl file into the /Data/ folder.

• Step 3:- Download Procfile from the current report and delete the old Procfile from the fuseki-heroku folder and replace it with the one I have provided.

• Step 4:- Open Procfile using any text editor and make changes according to your rdf file. As in below screenshot you can see my file name is product.ttl make sure to changes according to your rdf file name.
  

• Example of Procfile:- Let's say your rdf name is record.ttl then your required Procfile will be

web: ./fuseki-server --update --port=$PORT  --file=Data/record.ttl /record 
private: ./fuseki-server --port=56276 --file=Data/record.ttl /record

• Step 5:- Create a new account (If you haven't already) on Heroku & create a new app with any name you want, for this tutorial I've used procut-sparql

• Step 6:- Install Heroku Cli in your system from this link

• Step 7:- Now open terminal / Powershell / command Line in fuseki-heroku folder and type command

  heroku login
  

  (make sure to add heroku in your system varaible) & login with your account.

• Step 8:- Now be in the same folder fuseki-heroku and type

  heroku git:remote -a your-app-name
  

  make sure to change your-app-name to your app's name. Example - Since my app name is product-sparql the required command will be

  heroku git:remote -a product-sparql
  

• Step 9:- Now run these command one by one in your terminal

```
git add .
git commit -am "make it better"
git push heroku master
```

Now, open your app like this https://your-app-name.herokuapp.com/.

In my case it's https://product-sparql.herokuapp.com/

Now go to control panel and select your rdf name and run sparql query.
