Data Management meeting held the 24/11/2003

Present: C.Cioffi, J.Closier, M.Frank, G.Kutznetsov, F.Loverre, 
         S.Ponce, A.Soroko, A.Tsaragorotzev


Status reports:

Bookkeeping (S.Ponce)
=====================
A new version of the bookkeeping web interface is released.
The bookkeeping interface should now be able to handle
arbitrary processing steps.
The Ganga interface to access the bookkeeping information is
under development.

Ganga (A.Soroko)
================
Alexander contacted a collegue from ATLAS to see if a common 
effort on the job options editor is possible. Alexander is
now concentrating to connect Ganga to the DIRAC job submission
interface, determine the necessary parameters and manage the
output delivery. 

POOL integration (M.Frank)
==========================
Technically the problems to read a standard oodst file and
write it in POOL format are solved. The process is now going
into a second iteration to identify existing deficiencies
in the Gaudi object description and to complete the xml description
files.
Carmine reported, that the EventSelector implementation for
POOL is ready and he also adopted the interface for the generic Gaudi
event selector. The next step is to convert the event selector
from the GaudiDb package, read an oodst file and write it using the
full machinery.

File Catalog (A.Tsaragorotzev)
==============================
Developments currently stalled. For the time being a storage element
is mounted to lbnts2 for I/O sandboxes.
Since the ARDA file catalogue may come later than expected, it will
be necessary to provide slices either a POOL based catalogue or/and
from the bookkeeping database. CMS apparently have a tool to create
XML catalogues from their bookkeeping database.

Production tools and DIRAC (G.Kutznetsov, A.Tsaragorotzev)
==========================================================
Gennady reported, that he is now focussing on the job submission
to Dirac. Markus had some concerns, that the job information is
purely stored in XML. This may be problematic for large scale 
productions.
Andrei mentioned, that for the GRID some BBFTP problems are solved,
BBFTP now works with purely outgoing connections which are expected
to be availible on GRID worker nodes. Some job monitoring
(See also extra meeting: http://agenda.cern.ch/fullAgenda.php?ida=a036380#2003-11-26 )
is included in the workload management system, where the monitoring 
information will be stored in the connected database.
