Sparnatural is a visual SPARQL query builder written in javascript.
It supports the creation of basic graph patterns with the selection of values with autocomplete search or dropdown lists. It can be configured through a JSON-LD or OWL configuration file (that can be edited in Protégé) that defines the classes and properties to be presented in the component.
You can play with online demos at http://sparnatural.eu/#demos.
This is a fork of the main repository. The changes made are mainly about using the MatVoc vocabulary on a GraphDB store.
