SPARQL Playground: A Block Programming Tool to Experiment with SPARQL.
Paolo Bottoni, Miguel Ceriani · IRIS Research product catalog (Sapienza University of Rome) · 2015
SPARQL is a powerful query language for SemanticWeb data sources but one which is quite complex to master. As the block programming paradigm has been succesfully used to teach programming skills, we propose a tool that allows users to build and run SPARQL queries on an endpoint without previous knowledge of the syntax of SPARQL and the model of the data in the endpoint (vocabularies and semantics). This user interface attempts to close the gap between tools for the lay user that do not allow to express complex queries and overtly complex technical tools.
