 ==== Queries ====
-In GroIMP the project graph is considered to hold almost all information on the simulation. Therefore it can also be seen as a knowledge graph. To retrieve this knowledge rgg uses the [[tutorials:common_graph_queries|XL query system]]. To use this queries in a java block they have to be framed by ''(*...*)'' as shown in the examples below. In that way they return a collection object, which then can be like other java objects. Moreover GroIMP comes with a set of predefined  [[:15_cheatsheet:operators|Analytical methods]] to analyze this collections.

 As shown in the example below in ''%%count((*M*))%%'' this queries work with the concept of java objects. Therefore ''(*M*)'' is selecting all instances of Branch because Branch extends M. This also works with interfaces.

 The concept of an replacement rule in XL follows the 'Lindenmayer-form' where basically all parts of the project string that are similar to the left part (before ''%%==>%%'') are replaced by the right part ( behind ''%%==>%%'').
-The left part can thereby be any [[tutorials:common_graph_queries|xl-query]].
+The left part can thereby be any [[02_user_tutorials:15_rules:01_xl-queries-and-operators|xl-query]].
 The right part (the production) is a collection of Nodes ( instances of either turtle commands, 3d objects or modules) which are linked by different edges. In the example below only successor- and branch-edges are used. A node that is separated to its predecessor by only a white space is added as a sucessor to the predecessor. A Node or a set of nodes framed by square brackets in that is added to the predecessor with a branch-edge.
