Hi,
I'm evaluating BRMS's for a new project at work.
JBoss Rules today swung into pole position however I am unclear on a
number of features. I wonder whether this user-group can help?
I list a number of aspects I "think" are currently missing in JBoss
Rules together with my thoughts: If anybody can clarify the position,
provide alternatives or help push JBoss Rules I'd be pleased to hear!
* We require ruleflow (where rules run sequentially; like
"identify all machines X" then "calculate prices" - not perhaps a
good
illustration as this could be written as one rule "calculate all prices
using machine XXX"!!!). Ideally "dynamic" ruleflow is required too -
where the next rule in a sequence is determined by the outcome of a
preceding rule (I have seen dynamic achieved with "trigger" Facts
asserted as the RHS of rules however our "Business Users" cannot be
expected to author rules following this design pattern. I have also seen
static implemented with salience). Is ruleflow (static or dynamic) part
of 3.2 - otherwise we'll need to categorise rules having different types
fired throughout a "coded" process in Java.
* A J2EE runtime to provide scalability of the RETE engine. We
need to have the engine being shared across sessions on a web-server.
What experiences have others had? Do you simply provide a working memory
instance per session (how does this scale horizontally?). I also read
that an Application Server runtime would be part of 3.2, is this true?
* A rule authoring environment for end-users. I read on Mark
Proctor's blogg that this is in development but is it set for inclusion
in 3.2 and does it handle DSL too; otherwise we'd have to write out own?
With kind regards,
Michael Anstis

Anstis,
We don't have ruleflow, but we do have AgendaGroups which can provide a
form of rule flow, just that its actually stack based. I'm working on a
more general ruleflow idea at the moment, it may make it into the end of
Q1 release, but its not defnite yet.
Normally you cache the rulebase in a singleton and then just creating
working memory instances as and when you need to - creating a working
memory is light.
The guided gui builder is for 3.2, it's web only based on GWT, I believe
that it will also do DSLs (Mic will have to confirm that).
