text: **3.7 SPARQL Manager**
  
  The SPARQL Manager provides a graphical user interface (GUI) for sending user defined queries to 
  the Virtuoso SPARQL query engine. 
  
  The powerful SPARQL Protocol and RDF Query Language are primarily aimed at professionals for 
  querying metadata as Linked Data. A basic knowledge of the DCAT-AP specification is highly 
  recommended. 
  
  In the future, users of the SPARQL Manager will be able to save their queries for scheduled 
  execution. Additionally a notification will be send to the user when a result has changed. 
  
  Clicking the info icon in the upper right corner will display a step-by-step walkthrough of all 
  components with a short info about their function. 
  
  This is possible in both of modes of the SPARQL Manager, the search and the assistant mode, which 
  will be described in the following sections.
