<DIV></DIV>as soon as MVEL is ready we'll do an M1, but the ruleflow part is
not exposed to thte drl language yet, that will take a few more

do have AgendaGroups which can provide a form of rule flow, just that

defnite yet.<BR><BR>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.<BR><BR>The guided gui builder is

<P><FONT face=Arial size=2>JBoss Rules today swung into pole

<P><FONT face=Arial size=2>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!</FONT></P>
<UL>
<LI><FONT face=Arial size=2>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.</FONT> <BR>
<LI><FONT face=Arial size=2>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?</FONT> <BR>
<LI><FONT face=Arial size=2>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?</FONT> <BR></LI></UL>
