YASGUI is a user-friendly interface to query any SPARQL endpoint. YASGUI codebase was started in two main parts: the quey editor and visualization SPARQL results. Recently the author of the tool - Laurens Rietveld announced two additional libraries - YASUE (Yet another SPARQL Query Editor) and YASR (Yet Another SPARQL Resultset GUI). Both libraries are completely client-side, and are customizable and extendable.

YASQE Features

• Syntax highlighting and checking 
• Prefix autocompletion (using prefix.cc), and property/class autocompletion (using the lov API).
• You can configure YASQE to use other completions as well. 
• Supports executing queries via ajax requests 
• Share your query with others 
• Use keyboard shortcuts

YASR Features

• Handles any SPARQL resultset (XML/JSON/CSV/TSV) 
• Automatically fetch URI labels (shown when you hover over URIs), using the preflabel.org API Plugin-based: Add your own visualizations to YASR (ot even better: submit a pull request in order to incorporate it in YASR)

Combining YASQUE and YASR is straight forward, as this show
