As already reported by Pasha, the web page for the LCB meeting in
Marseilles
is at the URL: http://marcpl2.in2p3.fr/LCB/
This was, I think, a very interesting meeting, the 3rd LCB workshop
following previous meetings in Padova in 1996 and Barcelona last year.
In the introduction, the chairman said:
  " We are now at a turning point"
Effectively the first and second workshop were totally unproductive.
At the time, the majority agreed that the proposed LCB line
(Objectivity,
LHC++) was the way to go. Since one year, things have considerably
changed:
  - the LHC++ project has been recognized to be not the way to go.
    This project was based on commercial components and these components
    did not correspond to what physicists want to see.

  - The Objectivity line has serious problems (to phrase it
positively!).
   The number of experiments planning to use Objectivity is now quickly
   approaching the absolute 0 (just wait for the next workshop).
   Many experiments are showing interest to the combination of Root
   for the Event store and RDBMS solutions like MySQL or Oracle
   for the Event catalog.

  - As a consequence, Root is seen as the emerging solution.
    In particular, it is now clear that nobody is interested by these
    grandiose projects consuming a lot of manpower to collect the
    "so-called" user requirements and implement unrealistic prototypes
    not faced to the reality of the experiments and users.
