LD-VOWL (LinkedDataVOWL) extracts ontology information out of arbitrary SPARQL endpoints and shows the extracted information in an overview visualization using the VOWL notation (with minor modifications).


LD-VOWL requires Node.js to be built.


  1. Download and install Node.js.
  2. Clone this repository running git clone
  3. Run npm install in the root directory of LD-VOWL to install the dependencies.
  4. Run npm run-script start to start a local webpack development server on port 8080 or run npm run-script deploy for a production build.


To get a production build, run npm run-script deploy. After the build is finished, the results will be inside the dist directory.


In order to run the unit tests, run npm run-script test.
