The new address for the Event Model documentation is:
https://twiki.cern.ch/twiki/bin/view/LHCb/LHCbEventModel
The LHCb Event Model describes the event data classes and their
relationships. An introduction can be found in the
Event Model
Tutorial.
The model was developed during late 2001 and early 2002 (see
minutes of Event Model and related meetings) using the conventions described
in LHCb 2001-142 (also in .doc
format). This glossary of data types may be
useful in understanding the document. Other
presentations describing
aspects of the LHCb Event Model are available. A
review of the event model took place in summer 2005 - the review documents are
in the review TWiki.
All event model classes must be defined in XML, which is then parsed by the Gaudi
Object Description package to produce C++ header files and the
dictionaries required for persistency. Every event
model class must have a unique Class ID, allocated by the
Event Model Coordinator. The currently defined Event classes and Class IDs
are listed here (also in .xls
format).
Changes to the event model are recorded in the
LHCbSys release notes.
The Event Model is implemented in the packages shown below.
