These SPARQL CONSTRUCT queries are meant to contain rules for inferring additional triples. RDF repositories can execute these SPARQL queries and add resulting triples as inferred triples, effectively creating a light-weight rule framework. By default, each SPARQL query should only be executed once. 

Other types of queries (SELECT, ASK, INSERT, DELETE) are not allowed. Implementations of Simple SPARQL Rules should take care that INSERT and DELETE queries are not executed, as this could lead to unforseen behaviour and security issues."""@en ;

If there is a set of queries that have the same number, then the sequence of execution of these queries in this set is arbitrary. 
Queries without numbers should be executed before queries with numbers.

Numbers need to be integers. A query can have only one number."""@en ;
