Notice that the metadata annotations must precede 'when', not 'then'.

rule x

@Purpose( "purpose of x" )

You may use more than one such metadata, e.g.,

rule x

@Purpose( "purpose of x" )

@Rulename( "this rule is called 'x'" )

when

hi Laun,
   I tries with your solutions but i couldn't find the way to configure the meta - data part in rule file to read.
   I came across with following issues when trying to read it from a given code.

[12,2]: [ERR 102] Line 12:2 mismatched input 'AT' expecting 'then' in rule "create new Instance"
   Exception in thread "main" java.lang.IllegalArgumentException: Could not parse knowledge.

i think this might be a issue with a @ sign in the rule file but i think i this kinda of annotations will help to specify the
main rule name. Or is there any way to identify or filter out the main rule name from file.

BTW your this solution help me a lot.
thanks

You might use the API to retrieve all rules in your KnowledgeBase

KnowledgeBase kBase = ...;

for( KnowledgePackage kp: kBase.getKnowledgePackages() ){
    for( Rule r: kp.getRules() ){
            String name = r.getName();
            String purpose = r.getMetaAttribute( "Purpose" ); // or similar - see below
            System.out.println( "Rule " + name + ", purpose: " + purpose );
      }
}

Rule names may not provide sufficient information. You could add arbitrary metadata to your rules, e.g.,

rule "pqx"
   @Purpose( "locates very interesting facts" )
   when
   ...
end
