This project has been superceded by the Java-based CLAS12 analysis package "COAT."

• John T. Goetz goetz@jlab.org

The CLAS12 Detector Geometry Library (CDGL) consists of a single core library which is used by three provided interfaces:

• Command-line query tool (clas12geom),
• GEMC (Geant4 Monte Carlo) simulator plugin,
• Clara (CLAS Reconstruction and Analysis Framework) service.

The underlying database uses the CCDB scheme borrowed (unchanged) from the Glue-X software project. A minimal set of parameters describing the detector is stored in the database, along with misalignment and warping parameters. These are read in by the CDGL which calculates the requested values (drift-chamber wire end-points for example) and returns these in different formats depending on the receiver: XML for command-line and Clara, in-memory volume map for GEMC.
