I thought that a lot of the functional requirement were actually common with
FRBR and FRAD : they are broad, but they do exist. Am I mistaken ? Or do we
need to declare something more specific ?

Then, we would need to add things like requirements for authorized access
point, variant access points, statements, core elements, and other such
basic concepts underlying RDA.

Another lightening talk for the joint meeting in DC2010 ? If we don't start
with that kind of stuff, it will be difficult to define what are the
community needs in terms of patterns definition.
