class=Apple-style-span style="FONT-SIZE: 13px">While I agree with Edward on the
value of an open relational schema for reporting and similar tools, I think the
choosen path is more valuable. If you have needs for an open schema, you'll
almost always better served if you design it yourself. With some interceptors in
the right places (jBPM4 seems to have the right hooks to plug them in) you can
keep your report schema aligned with the engine's data, without disturbing it
too much. Even jBPM3's very open and flexible schema is not good enough with
some kind of processes (I have some 150+ nodes, 200+ variables, very long
financial processes to manage), so you'll end up with something custom anyway.
If you design it flexible enough, however, you could come up with an interesting
extension.</SPAN></SPAN></FONT></DIV></FONT></DIV>
