Yet Another Sparql Query Editor

Funded by


YASQE is part of the regular YASGUI web application. YASQE provides a simple syntax highlighted text area, bundled with features such as autocompletion, and the option to query SPARQL endpoints.
var yasqe = YASQE(document.getElementById("showcase"));
(or, if you would like to instantiate YASQE from an existing text area, use var yasqe = YASQE.fromTextArea(document.getElementById('textAreaItem'));


YASQE features:
  • Completely client-side
  • SPARQL syntax highlighting and error checking
  • Extremely customizable: All functions and handlers from the CodeMirror library are accessible
  • Persistent values (optional): your query is stored for easier reuse between browser sessions
  • Prefix autocompletion (using
  • Property and class autocompletion (using the Linked Open Vocabularies API)
  • Easily add your own property and class autocompletions if you have them
  • Handy keyboard shortcuts
  • Possible to execute the query directly
Combining YASQE with the YASR library (which visualizes SPARQL results) is easy: all you need to do is define YASR as a handler to the YASQE query method. See this example gist.

Used by

YASGUI (or one of its components, YASQE/YASR) is integrated in common triple-stores such as Apache Jena , OpenRDF Sesame and ClioPatria.

It has seen uptake in Linked Data tools as well, including

  • Gosparqled (demo), an extension of YASQE providing context-dependent property and class autocompletions
  • Snapper (demo), a browser based Turtle editor
  • Visu (demo), the first library to extend YASR with Google Chart functionality
  • Brwsr, a Linked Data browser
  • Trifid-LD, a lightweight Linked Data server and proxy

Publishers are using as well, such as , the Smithsonian American Art museum ,the German National Library of Economics (ZWB) , Linked Open Vocabularies , the LOD Laundromat , MetaLex , linkedArc and the CEDAR project.


A big thanks goes out to:
  • The people behind the Flint SPARQL editor for publishing the javascript SPARQL grammar
  • Marijn Haverbeke for his great work on the CodeMirror library syntax highlighting library
  • Pierre-Yves Vandenbussche and Bernard Vatant for their useful Linked Open Vocabularies service, of which I use the API to autocomplete properties and classes
  • Richard Cyganiak for his simple but effective service, which I use for autocompleting prefixes.
