<p class=MsoNormal style='margin-left:36.0pt'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>Talking about new features to be
included in the new release, I think the most compelling might be the ability
to use Maps as facts (ie, from the point of view of a complete DROOLS newbie).
Technically POJO is a Map with some restricted functionality (can’t count
properties, check for property existence, etc). Is it really a big change? The
rule formulation will remain the same from what I understand and the LHS like<o:p></o:p></span></font></p>
<p class=MsoNormal style='margin-left:36.0pt'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal style='margin-left:36.0pt'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>
Map(name == ‘myName’)<o:p></o:p></span></font></p>
<p class=MsoNormal style='margin-left:36.0pt'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal style='margin-left:36.0pt'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>Will simply mean any map object
which has a key ‘name’ and value for the key is
‘myName’. The ‘type matching’ feature would be kind of
less useful in case Map fact is used, but this can probably solved through
introducing some default ‘type’ key which Map object should have
and in a very simplistic implementation just include ‘type’ as a
constraint.<o:p></o:p></span></font></p>
<p class=MsoNormal style='margin-left:36.0pt'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal style='margin-left:36.0pt'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>Another alternative (which might
probably be more ‘backward compatible’ with existing implementation)
is to dynamically generate POJOs from Map definition. ‘type’ or
‘class’ key will correspond to a full qualified class name, all
other keys found in the map – POJOs properties. Or ‘type’ can
stay ‘anonymous’ – might be useful in some cases as well….<o:p></o:p></span></font></p>
<p class=MsoNormal style='margin-left:36.0pt'><font size=2 face=Arial><span

<p class=MsoNormal style='margin-left:36.0pt'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>The ‘weakly defined’
fact objects might be quite useful in some cases, eg when rules ‘cross
cut’ business domain. Kind of ‘dynamic rules’ </span></font><font
