Hi,

Could you please explain the use of XML and word docs uploaded , some 
examples ,can I refer these files in the rules which I write in Guvnor .

Hi,

When you upload files to Guvnor XML and .properties files are stored 
under XML, properties and everything else for example Word files or PDF 
files go to Other assets, documentation.

Hi All,

Can we have a dynamic declarative model build in Drools Guvnor. 
For example if I have certain tables in database say employee, company, 
address ,can we have a drop down for these tables so that end user can 
select any one one and  based on that selection model in Guvnor is 
created.
At present we specify the names of the model say employee and then add 
fields into it. say employee ID etc.

Many Thanks,

Nilima

The following code generates NPE in ReteTuple.java 

rule 
                 when
              Membership ( $regDate : regDate)
              Segment ( startDate < $regDate || startDate > endDate )
        then
                      System.err.print(?Invalid start date?);
end

I am new in Drools and don?t know much about DRL scripting. It works fine 
I
use && operator instead.

Can you please explain the use of "XML,properties" and "Other assets 
,documentation" links available in Guvnor.

I think though that the majority of uses for a rules engine is in a 
business
context, where they don't use astronomical time. 

If the doctor's orders are:
"You cannot get out of bed for 2 months"

This means 59 days if he told you February 1st, and it means 62 days if he
told you July 1st.

So at least for me, I am going to have to work out a plan that involves
GregorianCalendar.

This is a particularly bad example, because doctors can't say that - at
least not one I'd trust ;-)

I'm arguing that you cannot expect a computer program to relieve you from
the burden of defining what you mean by a "duration of one year" (or 
month).
Some legal rules require a person to have a certain age, and it is (for
humans)
more convenient to decide this on a person's birthday YMD plus an 
increment
in the Y number. If  your application requires you to use an increment in
the year
component of the YMDhms representation of a point in time, then you are
indeed stuck with Calendar and the resulting overhead. (Memoizing
the results of YMDhms +/- n years might speed things up, for the usual
price.)

But many applications would be satisfied with using a fixed duration for
a year in terms of 365 or 365.25 or some such value. If, for instance, you
have a  library, and you must decide to move a book into deep storage
"if it has  not been requested for more than a year" you might calculate
this (faster) by adding 356*24*60*60 to the clock value of the last 
return.

Hi All,

As you might have understood with my so many questions :) I am looking at
the capabilities of Drools and our team is looking at a comparitive 
analysis
between Drools and ILOG
One of the feature which is greatly desired is natural language editor. So 
I
am planning to create my own DSL creator "Poor man's version" which will
introspect the class and generate some DSLs for our need.
An old Blog
http://blog.athico.com/2007/03/standards-based-approach-to-natural.html 
points
to an interesting article. Does anybody knows where this item is in the
roadmap.

Another suggestion I had was on the Roles and Permissions for the users.
There is a option in drools to permit access for a user to a package and
category. It would be good to add Status to the mix so that the novide 
user
is prevented from moving rules to production. Small change.. big gain :)

Does anybody has a pointer to a demo of drools showing its capabilities. 
Or
a comparitive analysis with ILOG.

We are able to show lot of good use for the tool.. but the data model we
have is causing us big headaches in writing easily understandable rules.
The scenario is that we have a "lot" of attributes of a fact. And as part 
of
model extension lot of attributes are constantly added to the fact.
To make this easier so that we do not have to update the model - we have 
put
a (key value pair) for the attributes.

So the model structure is

MainFact
   mainAttr1 String
   mainAttr2 String
   List additionalAttrs<AdditionalAttributes> = new
ArrayList<AdditionalAttributes>();

AdditionalAttributes
   attrName String
   attrValue String

So now in guided editor or DSl editor it becomes a nightmare to write a
rule.. and our rule writers will beat us up if we ask them to write a rule
like
aa: AdditionalAttributes (attrName == "var1", val : attrValue)
a: MainFact (mainAttr1 == "mainVal", additionalAttrs contains aa)

Any easy solution for this :)

Thanks,
Amit

Try to do this in bank application. People come 1 hour after they date
expired and try to charge them for sooner withdrawal because you
calculate with 365.25 not 365 days. You will be kicked, believe me.
