Description

This branch produces a local semantic web application. Currently, you are able to query library dataset that is persistent on Apache Jena Fuseki's local server. And using postman's get/post request for a specific string input, we are able to view the data via D3.js.

Environment Setup

• verify that your environment is set to run on java 8
• need to have your own local Apache Jena Fuseki with dataset name ds and upload file strict_query_fixed.jsonld seen under folder data

How to run Program

• clone the repo
• set up Apache Jena Fuseki, create dataset name ds, upload .jsonld files into Fuseki's UI. You can access their UI via localhost:3030
• cd into TripleDataProcessor folder and run mvn package then mvn tomcat:run. Make sure you're running java 8.
• go to a browser and type http://localhost:8080/TripleDataProcessor/webapi/search for search UI, which will redirect to /myresource to display D3
• http://localhost:8080/TripleDataProcessor/webapi/myresource for raw triples of returned query
• http://localhost:8080/TripleDataProcessor/webapi/myresource for D3 display
• If error 500 (Server issue), run mvn install then mvn clean to download all dependencies

Expected Output

• should see D3 display based on user given input in search bar

In Progress

• We are working to get the project running on library server.
• querying external SPARQL endpoints
