There were more "bugs" on these two slides (which are hopefully fixed
in the next draft). The syntax for item identifiers and subject
identifiers is thought to work exactly like in CTM.

Currently, they're only user-defined axes, they allow to return bags
only. And it's all WIP, as always.

There was no mind-shift, there was a people-shift.

It was stated before (writing this mail, maybe not publicly before
your's), but to be sure, I'll write it again: The basis we're working
on is http://isotopicmaps.org/tmql/tmql.html (2008-07-15) and the
current implementation of TMQL4J (http://code.google.com/p/tmql/)
