Description
We report on the software for Object-oriented Reconstruction for CMS
Analysis, ORCA. It is based on the Coherent Object-oriented Base for
Reconstruction, Analysis and simulation (COBRA) and used for
digitization and reconstruction of simulated Monte-Carlo events as
well as testbeam data.
For the 2004 data challenge the functionality of the software has
been extended to store collections of reconstructed objects (DST) as
well as the previously storable quantities (Digis) in multiple,
parallel streams.
We describe the structure of the DST, the way to ensure and store
the configuration of reconstruction algorithms that fill the
collections of reconstructed objects as well as the relations
between them. Also the handling of multiple streams to store parts
of selected events is discussed. The experience from the
implementation used early 2004 and the modifications for future
optimization of reconstruction and analysis are presented.
