All: We are using Drools to detect specific events/conditions in our system. In the 'then' condition of Drools rule, we would like to persist the "Rule Id" of the rule that created the specific event/condition This is because all our reporting is based on "rules" as filters, where users can look at exceptions by specific rules. Is there a suggestion or sample as how can the "Rule Id" be persisted or indicated in the then condition that is immutable or can be long-lived. The current approach of using Rule Name itself as the ID is brittle as this can be changed and suddenly all reports would break. If we assign ID's to rules, where do we keep the mapping of RULE ID to Rules. If we store rules in GUVRNOR is there a way we can get Rule Id's for Rules?

Is the reply correct?

There are obvious mechanisms to create metadata on the object model in Drools and while there are data structures in the rules to store metadata setting user-defined metadata on rules does not seem to have supporting predicates.

I would be interested in seeing a rule metadata example.

Thanks everyone for the replies. Wolfgang, as a note - in JavaDocs the method getMetaData("attribute") is deprecated http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/apidocs/index.html Does anyone-know why?

Hopefully - getMetaData() would be here to stay!

I think the suggestion to use ID meta-data attribute on rule is the best and most stable!!

is there a way to maintain an ID ? Thanks, Abhinay -- View this message in context: http://drools.46999.n3.nabble.com/Rule-Id-for-a-Drools-Rule-tp2914385p402...

I wasn't aware of the fact that people use something else other than nabble. Will keep in mind from next time and put my question more clearly. My question is, I know there is a UUID for everything that is created in guvnor. But, is the UUID, created duration an asset creation, unique, and does the value of UUID change when any change is brought to the package or asset (i have checked with renaming a rule and the value doesnt change). Does the UUID depend on asset name and package ? i.e. if i have two rule in two different packages with same name, then is there any change that their UUID may match ? Will the UUID remain same if i export the package and import it somewhere else ? Basically, i need a Unique Identifier for all my assets in Guvnor and i guess UUID can help me out.

hi mike, Here is a scenario, Lets say I have rules named "rule1", "rule2" inside guvnor. I am extracting the rule names using REST api, pointing to some url http://../package/packageName/assets. I need the rule names in my application, so I have kept the rule names in my DB. If tomorrow I need to change the rule name of "rule1" to "xyz", how does my application keep a track of which rule name has been changed out of the two and update the same in my DB. For the time being, I am using the UUID, and its doing the job very well. But, if it becomes obsolete in the future, is there a replacement to it ?
