Hi Sandro,

UC&R is very important and should be published. It shows use cases and code
examples for RIF and its (future) dialects. The requirements are important
for the development of future RIF extensions. 

A lot changed in the document since the last draft. I also started to give
examples formalizations (using BLD).

Sandro,

Looks like a good plan, but whether 1 year is enough depends on the speed
of the progress.  As you know, sometimes we hit unexpected snags.

I have some questions/comments:

1.  You wrote:
        - BLD, DTB, and SWC  -- finish up what're working on now;

    Was the omission of FLD intentional?  Did you mean BLD/FLD?
    What about UC&R?

2.  When you are talking about 1 year, do you mean May 2009?
    Is it a kind of 2nd phase?

3.  Getting LP + FOL + PRD dialects to the last call in < 1 year is very
    ambitious, but I assume that we can get an extension on that.
    (In fact, LP and FOL are mainly done as part of FLD, but significant
    work is still ahead.)
