Thanks for the kind words, Tim.
I wasn't aware of the  <http://liris.cnrs.fr/~sbimonte/view.pdf>
http://liris.cnrs.fr/~sbimonte/view.pdf presentation. Thanks for mentioning
it. It's a little out of date (2006), but it has a fair amount of depth, and
I recommend it to anyone wanting a crash-course in mondrian's architecture.
By the way I just checked in a fix for the "MMM" bug. Change 11647, will be
in mondrian-3.1.

Hi, Julian... 
I just subscribed to this list, hoping to catch these kinds of great tips.
I didn't expect them so fast though!  GREAT WORK!
My history with OLAP so far is that I got the JPivot/Mondrian example at
http://liris.cnrs.fr/~sbimonte/view.pdf working under Eclipse/Tomcat, and I
started adding new Mondrian schemas and new databases within this app (2 so
far, with probably 10-12 more on the horizon).  I can't say there were no
struggles, because there were multiple new-things-to-learn, but I was able
to quickly prove that these two tools can accomplish what I needed, and now
my app continues to grow.    
My heartfelt thanks to everyone who has given of themselves to create a
fantastic product that lets me impress my new boss (with relative ease).  I
hope to be able to contribute back someday soon!

I think the example had extra '\'s because it was taken from Java code
(inside java strings, " and \ need to be escaped). That's why it worked for
you to change '\\.' to '\.'.
If you had changed '\"Time\"' to '"Time"' it would probably have worked too.
It worked without Time because dimension names are optional - although I
recommend using dimension names, because it makes your code clearer and
reduces the amount of searching mondrian has to do.
I also see that you changed MMM to mmm. I'm guessing that in your dimension
months look like 'jan' rather than 'JAN'.
Thanks for letting us know what works.

Finally got this working..

Interesting that it works without [\"Time\"]?

CurrentDateMember([Time], '[yyyy]\.[mmm]').Lag(12) :
CurrentDateMember([Time], '[yyyy]\.[mmm]')
