document: visKQWL , a visual renderer for a semantic web query language KiWi is a semantic Wiki that combines the Wiki philosophy of collaborative content creation with the methods of the Semantic Web in order to enable effective knowledge management . Querying a Wiki must be simple enough for beginning users , yet powerful enough to accommodate experienced users . To this end , the keyword-based KiWi query language ( KWQL ) supports queries ranging from simple lists of keywords to expressive rules for selecting and reshaping Wiki ( meta - ) data . In this demo , we showcase visKWQL , a visual interface for the KWQL language aimed at supporting users in the query construction process . visKWQL and its editor are described , and their functionality is illustrated using example queries . visKWQL 's editor provides guidance throughout the query construction process through hints , warnings and highlighting of syntactic errors . The editor enables round-tripping between the twin languages KWQL and visKWQL , meaning that users can switch freely between the textual and visual form when constructing or editing a query . It is implemented using HTML , JavaScript , and CSS , and can thus be used in ( almost ) any web browser without any additional software .
