Event Data Model Status for the
                     February 1999 CDF Collaboration Meeting
                                   12-Feb-1999
                     RDK, to be presented by Liz Buckley-Geer


1) EDM work: a backwards-compatible upgrade to improve robustness of Offline and
productivity of Offline developers. Not holding up Offline development.

2) February: Generate and critize an EDM proposal with a transition plan
from current state to new model described in proposal.

3) March: Finalize and approve EDM proposal. Some slippage in schedule due to
constraints on such a high-impact infrastructure issue. Implement in April.

4) New model will be much more C++-oriented. Trybos used to shield users from
changes. Existing Banks classes will still work, for instance.

5) Continued F77 support at current levels for most important F77 software, eg.
BLOCAT(), BMAKE(), etc.

6) StorableObjects, more general and convenient than YBOS Banks, can be stored
in an event. Once stored, StorableObjects become read-only. StorableCollections
can also be stored directly in an event.
