SPARQL Trainer: learn to query the semantic web

The SparqlTrainer is an e-learning tool to practice SPARQL interactively. With the help of self-developed tests, consisting of individual questions, it is possible to train the different query forms (SELECT, CONSTRUCT, ASK and DESCRIBE). After entering a solution the learner will immediately see an evaluation of the request with the corresponding result. Due to different features, like password protection of tests and E-mail notification, an usage in support of courses is also possible.
