mining is {countryName:CF:Country.name}
If the mineral Quartz is selected, then the custom form displaying the
country list should only display Quartz-producting countries. For this,
the fact that mineral type Quartz was selected would need to be passed to
the custom form. Is that possible?

Re: [rules-users] Cutom Attributes in Drools
I would not store the result of the (missed) activation of a rule in a
rule
attribute, anyway. Can't you just use a dedicated fact(s) for that?
I face a similar issue where the target audience are business users i.e
users that dont really understanding or wish to get into logic. I am
finding myself having to resort to all sorts of tricks (using
categories/packages/standlone rule editor) to allow business users to
easily specify which rules are for what purposes and when they should
fire. I just cant rely on them using facts correctly to disable rules that
should not fire. In fact, I am now down to using only the standalone
editor and saving the rule xml in my tables (not guvnor) so that i have
full control over itemized rule display, rule search, knowledgebase
creation for different execution profiles, etc.
Overall, I increasingly tend to think rules for business users is a myth.
The business users wants rule-driven systems, yet they dont want to learn
drools. And drools DSL just doesnt cut it.

You can add any metadata using the format @name( value ) or @name(
key=value ). You can then look them up using rule.getMetaData().
Please notice that there's a bug (solved by an open pull request) that
does
not let you write just @name.
In order to use those attributes to control whether a rule fires or not,
you
can use the declarative agenda, i.e. add meta-rules to your knowledge
base
such as:
rule Meta
@activationListener('direct')
when
// assuming the attribute is @region( [value] )
$a : Activation( rule.metaData[ name ] != MyDesiredRegion, $objs :
objects )
// any condition on the tuple here, if needed
then
drools.cancelActivation( $a );
end
notice that you'll have to enable the corresponding option first:
KnowledgeBaseConfiguration kconf =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
kconf.setOption( DeclarativeAgendaOption.ENABLED );
KnowledgeBase kb = KnowledgeBaseFactory.newKnowledgeBase( kconf );
If you want to have rules override each other, watch out for an upcoming
feature, Defeasible logic.

Re: [rules-users] Is there a faster way of doing this in Drools ?
so you are using drools to build on-the-fly queries based on user input.
You could probably do this via static rules. Since you basically have 4
variables (price, avg_user_rating, num_ratings, category), you could write
4 rules, one each that filters based on one of the 4 variables and then
chain the execution through salience:
rule price:
salience 1
when
$p: Product(price in param)
then
add $p to result
rule avg_user_rating:
salience 2
when
$p: Product(avg_user_rating param)
then
add $p to result
and so on

Users changing rules IS the correct use-case of drools (I would even say
that if rules never change, drools is likely to be worse than pure
java).
What others said is changing the rules at each request by regenerating
and recompiling is not.
I can't imagine that users may change rules at each request, so you must
have, at least for some time (thus a lot of requests), a stable rule
base.
What is costly is to compile rules, but you already know that.
So the idea is to keep in some kind of cache the actual rules, and only
recompile them when they change.
The source of rules does not matter : you can generate the DRL according
to your configuration, or make you users directly write rules (with
guvnor, which will fits well if your rules are only basic filters).
The optimisation you have to do is to keep your compiled rules somewhere
(by serializing your KnowlegdePackages or simply keep it in a kind of
map), and reuse it until your source change : you have to find a way to
detect that rules (or the config that is used to generate them) have
changed, and then recompile a new up-to-date KnowledgePackage.
Thank you for your insights.
At this point I'm designing for the worst case i.e., I'm assuming the
rules
with change with every request.
Moreover, this can happen on a regular basis in the system I'm trying to
design.
Product
{
price
ave_user_rating
num_ratings
category
}
User wants to see Product with with the following rules
at t=t_1 : If product.category in {A,B}.
at t=t_2 : If product.category in {A,B} AND price 100
at t=t_3 : If product.category in {A,B} AND price 100 AND num_ratings
100
You can imagine the user changing these rules in a span of less than a
minute.
I understand that Drools is designed for cases when rules changes often.
But
can it support something like the one I described above where rules are
changing at a much faster rate?
Thanks.

document and use then, on the caveat that they understand they may
change on any release. It's not that I don't think it's a legitimate
request, I think it's perfectly valid. It's simply that we cannot be
tied down to an internal model, we need to be free to change that.
However users who code against those internal models will cry havoc if
we change them, if the think they are public apis.

Re: [rules-users] Building our own UI for Drools
On hosted mode: I have the same requirement i.e hosted site with lots of external clients using the same site, it is indeed impractical to deploy a guvnor instance for each client. Overall, from what I have researched, there are two things available to segregate rules by external client: categories and packages, but I decided against using them to achieve client segregation. The approach I have arrived on is to launch the guvnor standalone editor from my website, store the brl in my tables (the standalone editor provides javascript hooks to allow retrieving the rule brl/drl once the rule has been written). Effectively, the only thing stored in the guvnor repository will be the model to enable rule authoring. Originally, I was planning on storing the rules in the guvnor repository and using the rest api to list rule packages (prefixed by clientId) in my site. Since I am able to retrieve the brl/drl anyways (via standalone editor javascript hook, or if that feature were not available, then vi! a rest call immediately after rule has been authored), I decided to store the brl/drl in my app db. Since the rules are stored in my tables, I will have full control over client segregation. I have done a mini-POC to prove that this will work and it seems like it will, unless an expert on this mailing list can point out showstoppers/potential flaws/shortcomings of this approach. Hope this helps others who are faced with similar situations. Thanks G.

What we are looking for is, be able to share a common collection of ruleset and at the same time, be able to define their custom rules with their customization. At the moment, it is possible to achieve this by using role-based-authorization in Guvnor. I.e., you create some common packages that are designed to be shared by everyone. You assign package-readonly permissions to everyone so that they have read-only access to these common packages. You can also use Global Area to achieve same effect. Essentially Global area is a special package that can be shared by all packages. Then each user has package-admin permission for their own packages. The Workspace as I mentioned early will provide a more completely isolated environment for each user when multiple users are sharing one instance of Guvnor.

Re: [rules-users] Building our own UI for Drools
For #1 and #2, I am planning on using DSL that uses a separate model, built specifically for rule writing, that wraps around the actual application domain model. DSL sentences are not quite as user friendly, the rule writer has to pick from a huge list of DSL sentences as opposed to incremental condition phrase building available from the native rule editor, but there is no other way, short of building your own rule editor. The common rulesets, due to their very nature, I am not exposing to the clients for editing, they are internal. The KnowledgeBuilder api can load common rules (which could be in .drl files) in addition to guvnor rules.

Re: [rules-users] Data Modeling for medical expert system
I am in the same situation (and I suspect a lot of people with complex domain models are), which is: how do I let the user easily navigate my domain model while writing a rule. There is support for providing a custom form within a popup when a fact constraint needs to be specified. You can present it to the user whenever a fact constraint needs to be supplied to the rule. Since you are providing the contents of the custom form, you can represent your domain however you wish to, navigate it perhaps using a tree, or even let the user perform a mini search to get to the MeSH category. The custom form does not currently work with DSLs though, if you are planning on using DSL sentences. But you can write your own DSL widget that does (not too difficult, if you know GWT). For my project, the biggest utility value of drools is the standalone editor, the Guvnor rest api and the fact that it is opensource (so that I can customize it for my very complex needs) Thanks G. Patel From: Bruno Freudensprung bruno.freudenspr...@temis.com To: Rules Users List rules-users@lists.jboss.org Date: 11/08/2011 10:49 AM Subject:Re: [rules-users] Data Modeling for medical expert system Sent by:rules-users-boun...@lists.jboss.org Hi Dirk, Good to see that I am not the only one fighting with that question :-). I guess the general answer is: it depends on how large your enums might grow. For instance if your application is eventually supposed to help diagnosing (say) all MeSH diseases based on all MeSH symptoms, then an approach where every symptom and disease is a Java class is not an option; this would lead to so many classes that I doubt Drools user interface will handle that, or will be useful anyway (drop-down lists with thousands of items). The opposite approach consists in creating a few root Java classes like (say) Disease and Symptom and to store the MeSH hierarchy into a name attribute. The obvious drawback of the approach is that when your end-users will have to write the rules, they will be left with problems like: when Symptom(name == well... what's the name of this MeSH category??) then Disease(name == hmmm... can't remember the exact name of the disease as normalized in MeSH...) end I've posted a message on this topic (subject: Thoughts about rule authoring) and Michael Anstis kindly suggested a technical answer. I am afraid it did not fit my needs, but it could fit yours :-). For the moment I have no solution (like an intermediate approach) to my problem: I am stuck with approach #2. I have the impression that my problem requires a very tight integration between my database (MeSH) and the Drools suggestion engine. If you have another approach, I would love to know it ;-).

You'll need to raise a JIRA for an enhancement.
Dependent enumerations are currently only designed to operate between
enumerations.

2011/10/28 gpa...@tsys.com
I am trying to use data enumerations and running into a problem. Following
the Vehicle engineType/fuelType data enumeration example in the Guvnor
manual, I created the following enumeration list and it works:
'Vehicle.engineType' : (new test.VehicleHelper()).getEngineTypes()
'Vehicle.fuelType[engineType]' : '(new
test.VehicleHelper()).getFuelTypes(@{engineType})'
VehicleHelper:
public class VehicleHelper {
public ListString getEngineTypes(){
ListString engineTypes = new ArrayListString();
engineTypes.add(Petrol);
engineTypes.add(Diesel);
return engineTypes;
}
public ListString getFuelTypes(String engineType){
ListString fuelTypes = new ArrayListString();
if(Petrol.equalsIgnoreCase(engineType)){
fuelTypes.add(ULP);
fuelTypes.add(PULP);
}
else if(Diesel.equalsIgnoreCase(engineType)){
fuelTypes.add(BIO);
fuelTypes.add(NORMAL);
}
else{
fuelTypes.add(Default Fuel 1);
fuelTypes.add(Default Fuel 2);
}
return fuelTypes;
}
}
Above works as expected.
Problem:
I want to only have an enumeration on Vehicle.fuelType that depends on the
value of engineType, without specifying an enumeration on engineType. So,
I took out the first line in my enumeration list so that it is now:
'Vehicle.fuelType[engineType]' : '(new
test.VehicleHelper()).getFuelTypes(@{engineType})'
But that does not work. When I create a rule, VehicleHelper.getFuelTypes
does not get called and the dropdown for fuelType is not a list.
How do I get this working?
Thanks

Define FraudResultsDTO as a global. That way, you don't have to specify it in

Subject: [rules-users] Preventing re-evaluation on modification of 'output'
fact
We're building a fraud detection application that uses rules to analyze
orders and the buyers and recipients on those orders. As rules fire, they
modify an 'output' fact, which is an object whose only intent is to record
the results as rules fire. It's not used in the LHS of any rules other than
to get a handle to it, e.g.:
rule Rule 001 - Operator Flagged
enabled (FraudRuleEvaluationHelper.isRuleEnabled(Rule 001 - Operator
Flagged))
ruleflow-group orderAnalysis
lock-on-active
when
$order: OrderFact(operatorFlagged==true)
$results: FraudResultsDTO()
then
modify($results) {
addOrderSuspectReason(O)
};
FraudRuleConsequenceHelper.logRuleFiring($order.getOrderId(),
001);
end
We're finding that as the number of facts increases, the processing team
increases dramatically and I'm wondering if modifying the output fact the
way we do causes the rules to get re-evaluated to see if any activations
should be created or cancelled. Would removing the modify block help
anything? Should we be thinking about this in some other way?

Hi Ghanshyam,
Once the new JAX-RS based REST interface is in place (its not there yet,
but will come in soon), you can use following ways to retrieve rules
under a category. For example:
A HTTP GET request to URL http://host:portnumber/repository/categories
with Accept=application/atom+xml returns a list of categories in the
repository in Atom Feed format.
A HTTP GET request to URL
http://host:portnumber/repository/categories/testCategory1/assets with
Accept=application/atom+xml returns a list of assets under the
testCategory1 in the repository in Atom feed format.
A GET request to
http://host:portnumber/repository/categories/testCategory1/assets/testAsset1
with Accept=application/atom+xml returns an atom entry which is a
summary info of that asset as well as its meta data.
A GET request to
http://host:portnumber/repository/categories/testCategory1/assets/testAsset1
with Accept=application/octet-stream returns a binary attachment (if
that asset has a binary attachment as content).
A GET request to
http://host:portnumber/repository/packages/testPackage1/assets/testAsset1
with Accept=application/source returns the asset source in text format
(if that asset has a content in text format).
A GET request to
http://host:portnumber/repository/packages/testPackage1/assets/testAsset1
with Accept=application/json returns a json object which is the
summary info of that asset as well as its meta data.
Will this meet your requirement?
Thanks,
Jervis

Sent by:rules-users-boun...@lists.jboss.org
Hi Dirk,
You could also try using the existing remote API with Guvnor to push up
new content to the server.
Try:
1. GET
http://servername:port//org.drools.guvnor.Guvnor/api/packages/{packageName}
To pull the list of assets from the Guvnor API for a specific package.
2. You can POST a DRL using the existing rest api like so.
A) Create a post request to
http://servername:port//org.drools.guvnor.Guvnor/api/packages/{YourPackageName}/{YourAssetName}
e.g., POST h
ttp://servername:port//org.drools.guvnor.Guvnor/api/packages/{YourPackageName}/{YourAssetName}
B) Append your file data to the POST request as part of the request (as
you would with a POST'ed file upload).
REST based calls are handled through two classes:
org.drools.guvnor.server.filesRestAPIServlet
(in the drools-guvnor module)
and
org.drools.repository.remoteapi.RestAPI
(in the drools-repository module).
3. PUT calls handle updates to existing resources on the server, in a
similar way, with DELETE allowing removal of resources.
4. In terms of WebDAV, JCR also has a nice WEBDAV client implementation
available that extends Apache's httpclient, but with some WEBDAV specific
support built in.
The RestAPI class in Drools-Repository has some very good detail on how
this process works, and I'd suggest looking there if you have questions
(on the REST API side).
There is some discussion about REST, as well, currently on the dev mailing
list if you search Nabble.
A few ideas,
Andrew

Hi!
I would like to accomplish the same thing. Is there really no programmatic
way to do this?
I noticed that the files are uploaded through the eclipse-plugin using
webdav. Is it documented
what has to be done in order to install/update a drl using webdav?
Thx,
Dirk

[rules-users] Rule project referencing
Hello I am looking for a comparable feature in drools that works similar to rule project inheritance in ILOG JRules. In JRules, one can define a rule project A that contains all the base-level rules. Then, a new rule project B can be defined that references rule project A. This automatically makes all the rules defined in rule project A available in project B. One can then add to that set of rules by defining new rules in project B or override specific rules in project A. This feature is very handy for setting up client-specific rules. You can start out with a vanilla set of rules specified in project A. If a particular client wants additional rules (or wants to override the default functionality), a new rule project B can be created for that client that references project A and has the additional rules. No need to copy-paste all the rules from A to B. That way, if a rule is fixed in A, all referencing child projects instantly benefit from the update. Is there a similar feature in drools or a way to achieve the same functionality?
