[{TableOfContents }]


!!! Definition

The sparql markup allows to execute a query on the ontology repository. The result of the query will be rendered into the wiki page (instead of the query).

{{{
%%sparql...
}}}

After the SPARQL statement the following annotations can be inserted:

|| Annotation	|| Description	
|  @name	|  Gives the SPARQL the specified name. The name can be used as reference in other markups (like [InlineSparql|Doc InlineSparql])	
|  @zebramode	|  Renders the result table in zebra-style (gray/white).	
|  @border	|  A visual border is painted around the result table cells.	
|  @rawOutput	|  No abbreviations are used in the result table, but the full content (of literals for example) is printed.	
|  @showQuery	|  Besides the results of the query, also the query is shown in the view mode of the wiki.	
|  @sorting	|  The result table is sorted.	
|   	|   	



!!! Example

The sparql markup allows full support of the SPARQL 1.1. query language specification, which can be found here: [http://www.w3.org/TR/sparql11-query/]

The following simple example shows a query selecting all instances of the class Person:

{{{
%%sparql
SELECT ?x  
WHERE {
  ?x rdf:type lns:Person .
}
@name: exampleQuery
@zebramode: true
@border: true 
%
}}}

In the view mode the results of the query are shown.


!!! Hierarchy Table Example

[Demo - Simpsons]

{{{
SELECT (SAMPLE(?sub) as ?sub) (SAMPLE(?par) as ?par) (SAMPLE(?name) as ?name) ?concept
WHERE {
  {
    # bind si:abraham as root node
    BIND (si:abraham as ?sub) .  
  }
  UNION
  {
    # collect all parent child relations (will be conntected automagically to si:abraham)
    ?sub si:parent ?par ;
  }
  # display name and concept as table columns
  ?sub  rdfs:label ?name .
  BIND (?sub as ?concept) .
} GROUP BY ?concept
}}}
