About YASQE

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'));

Features

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 prefix.cc)
• 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.

Download the latest release

We provide a bundled release containing all external dependencies, and we provide a release containing just the YASQE core. If you choose to use the regular release, make sure to include jQuery and CodeMirror in your page as well.

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, a lightweight Linked Data server and proxy

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

Forked by

Forks of YASQE have been developed:

• YATE for the RDF 1.1 Turtle syntax.
• YASQE for SPARQL-Generate for the SPARQL-Generate language, an extension of SPARQL 1.1 for querying not only RDF datasets but also documents in arbitrary formats.

Thanks!

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 Prefix.cc service, which I use for autocompleting prefixes.
