−	In this example Wandora user sends Bob's query to Europeana's SPARQL endpoint. Query returns quartets of ''creator'', ''mediaURL'', ''source'' and ''title''. Wandora transforms each quartet into an association, and each association player into a topic. MediaURL topics include the audio url as a subject identifier.

 Addition to a general SPARQL knowledge, user should also know what kind of queries can be sent to the SPARQL endpoint. As a thumb rule, Wandora user should consult the documentation for the SPARQL endpoint. It usually explains what kind of information is stored in the database, which are base classes in information, etc. Also, usually documentation shows some example queries which help the user to start.

 In this rather long example Wandora user first send a query to DBPedia and receives a list of French movies. Then user enriches one of the created movie topics using Wandora's DBPedia extractor. First user starts the SPARQL extractor as shown below

 In this example Wandora user sends a query to Helsinki Region Infoshare's SPARQL endpoint and receives regional information about Helsinki's suburbs and population centers. Information includes geographical coordinates and polygons of city regions, hierarchy of regions and sometimes a description of a region. Wandora user builds up an occurrence of one region description and translates it to English and Swedish using Google translate feature.
